On 2 Aug 2018, 2 cases of rabies in cattle were recorded in Orkhon
soum (administrative subdivision) in the northern Darkhan-Uul aimag
(province). Samples from the sick animals were submitted to the
aimag's Veterinary Hygiene Center laboratory, where rabies was
confirmed on 6 Aug 2018.
The Orkhon Soum Emergency Commission was convened to establish a
restrictive regime, in prescribed areas, under the auspices of the
Ministry of Food and Agriculture. Mr Gankhuu, deputy director of the
provincial police office, said that the animals were killed and
disinfected. He warns herders to make sure they refrain from
approaching potential rabid animals, such as dogs, wolves, [red]
foxes, and corsac foxes.
The Aimag Professional Inspection Agency is responsible for providing
herders and citizens with advice, warnings, handouts, and inspections
of business entities and individuals who are selling raw materials of
animal origin. Within this framework, a team of doctors and
specialists from the Zoonoses Disease Research Center of Selenge aimag
(province) collected samples from animal products and raw materials
from 67 enterprises including food shops and sausage shops. The
Aimag's Professional Inspection Agency warns that the origin of animal
products must be certified [see comments].

[A different interpretation of the above information was published on
9 Aug 2018 by Xinhuanet News under the title "Mongolia reports two
cases of mad cow disease"
(<http://www.xinhuanet.com/english/2018-08/09/c_137378541.htm>). The
report says: "Two cases of mad cow disease were found in Mongolia,
local media reported on Thursday" [8 Aug 2018]. In view of the
significant public health hazard and international trade impact of
bovine spongiform encephalopathy (BSE), the issue that, most probably,
reflects a translational error is to be addressed in some detail.
Allegedly citing the country's Ministry of Food, Agriculture and Light
Industry and local media, the Xinhua report says, "The ministry found
the 2 cases of bovine spongiform encephalopathy or mad cow disease in
Orkhon soum (administrative subdivision) in the northern Darkhan-Uul
Province on Monday [6 Aug 2018].
"Mad cow disease causes a degeneration of the brain and spinal cord in
cattle, which can be transmitted to humans through eating beef.
"With more than 66 million livestock animals, Mongolia aims to raise
meat exports tenfold in the coming years and to diversify its heavily
mining-dependent economy.
"But frequent outbreaks of livestock animal diseases such as mad cow
disease and the foot and mouth disease have taken a toll on its meat
exports. In mid May [2018], 15 cases of mad cow disease were reported
in the Must [Most] soum of Khovd aimag, in the west."
As informed by Mongolia's government agency, the recent 2 cases in
cattle were, in fact, caused by rabies, an endemic fatal zoonosis in
Mongolia; they were not cases of BSE ("mad cow disease"), a disease
hitherto not identified in Mongolia (and it is hoped never will be).
The 15 mentioned cases last May [2018] in the aimag Khovd were
probably rabies as well. In 2017, rabies was reported from 15 of
Mongolia's aimags, including Khovd. Of the total of 218 rabies cases
in animals reported by Mongolia for 2017, 72 were cattle. The other
rabid farm animals were 80 small ruminants (sheep and goats), 32
horses, and 5 camels. The disease was obviously recorded also in
vector animals: dogs (13) and fauna (16).
According to Mongolia's periodic reports to the OIE, rabies has not
been reported in recent years from the Darkhan-Uul aimag. It may be
assumed that its recent introduction into this region is behind the
special attention paid by the authorities to the described event in
cattle there.
It is foot and mouth disease, recently spreading westward in Mongolia,
not BSE, that may potentially adversely affect exports, unless it is
controlled soon.
The described effort by the Zoonoses Disease Research Center of
Selenge aimag to collect samples from animal products and raw
materials from 67 enterprises including food shops and sausage shops
is obviously commendable; its relation to the rabies event in northern
Darkhan-Uul aimag deserves to be explained. - Mod.AS

Abstract 

Classical bovine spongiform encephalopathy (c-BSE) is the only animal prion disease reputed to be zoonotic, causing variant Creutzfeldt-Jakob disease (vCJD) in humans and having guided protective measures for animal and human health against animal prion diseases. Recently, partial transmissions to humanized mice showed that the zoonotic potential of scrapie might be similar to c-BSE. We here report the direct transmission of a natural classical scrapie isolate to cynomolgus macaque, a highly relevant model for human prion diseases, after a 10-year silent incubation period, with features similar to those reported for human cases of sporadic CJD. Scrapie is thus actually transmissible to primates with incubation periods compatible with their life expectancy, although fourfold longer than BSE. Long-term experimental transmission studies are necessary to better assess the zoonotic potential of other prion diseases with high prevalence, notably Chronic Wasting Disease of deer and elk and atypical/Nor98 scrapie.

Discussion We describe the transmission of spongiform encephalopathy in a non-human primate inoculated 10 years earlier with a strain of sheep c-scrapie. Because of this extended incubation period in a facility in which other prion diseases are under study, we are obliged to consider two alternative possibilities that might explain its occurrence. We first considered the possibility of a sporadic origin (like CJD in humans). Such an event is extremely improbable because the inoculated animal was 14 years old when the clinical signs appeared, i.e. about 40% through the expected natural lifetime of this species, compared to a peak age incidence of 60–65 years in human sporadic CJD, or about 80% through their expected lifetimes. Moreover, sporadic disease has never been observed in breeding colonies or primate research laboratories, most notably among hundreds of animals over several decades of study at the National Institutes of Health25, and in nearly twenty older animals continuously housed in our own facility.

The second possibility is a laboratory cross-contamination. Three facts make this possibility equally unlikely. First, handling of specimens in our laboratory is performed with fastidious attention to the avoidance of any such cross-contamination. Second, no laboratory cross-contamination has ever been documented in other primate laboratories, including the NIH, even between infected and uninfected animals housed in the same or adjacent cages with daily intimate contact (P. Brown, personal communication). Third, the cerebral lesion profile is different from all the other prion diseases we have studied in this model19, with a correlation between cerebellar lesions (massive spongiform change of Purkinje cells, intense PrPres staining and reactive gliosis26) and ataxia. The iron deposits present in the globus pallidus are a non specific finding that have been reported previously in neurodegenerative diseases and aging27. Conversely, the thalamic lesion was reminiscent of a metabolic disease due to thiamine deficiency28 but blood thiamine levels were within normal limits (data not shown). The preferential distribution of spongiform change in cortex associated with a limited distribution in the brainstem is reminiscent of the lesion profile in MM2c and VV1 sCJD patients29, but interspecies comparison of lesion profiles should be interpreted with caution. It is of note that the same classical scrapie isolate induced TSE in C57Bl/6 mice with similar incubation periods and lesional profiles as a sample derived from a MM1 sCJD patient30.

We are therefore confident that the illness in this cynomolgus macaque represents a true transmission of a sheep c-scrapie isolate directly to an old-world monkey, which taxonomically resides in the primate subdivision (parvorder of catarrhini) that includes humans. With an homology of its PrP protein with humans of 96.4%31, cynomolgus macaque constitutes a highly relevant model for assessing zoonotic risk of prion diseases. Since our initial aim was to show the absence of transmission of scrapie to macaques in the worst-case scenario, we obtained materials from a flock of naturally-infected sheep, affecting animals with different genotypes32. This c-scrapie isolate exhibited complete transmission in ARQ/ARQ sheep (332 ± 56 days) and Tg338 transgenic mice expressing ovine VRQ/VRQ prion protein (220 ± 5 days) (O. Andreoletti, personal communication). From the standpoint of zoonotic risk, it is important to note that sheep with c-scrapie (including the isolate used in our study) have demonstrable infectivity throughout their lymphoreticular system early in the incubation period of the disease (3 months-old for all the lymphoid organs, and as early as 2 months-old in gut-associated lymph nodes)33. In addition, scrapie infectivity has been identified in blood34, milk35 and skeletal muscle36 from asymptomatic but scrapie infected small ruminants which implies a potential dietary exposure for consumers.

Two earlier studies have reported the occurrence of clinical TSE in cynomolgus macaques after exposures to scrapie isolates. In the first study, the “Compton” scrapie isolate (derived from an English sheep) and serially propagated for 9 passages in goats did not transmit TSE in cynomolgus macaque, rhesus macaque or chimpanzee within 7 years following intracerebral challenge1; conversely, after 8 supplementary passages in conventional mice, this “Compton” isolate induced TSE in a cynomolgus macaque 5 years after intracerebral challenge, but rhesus macaques and chimpanzee remained asymptomatic 8.5 years post-exposure8. However, multiple successive passages that are classically used to select laboratory-adapted prion strains can significantly modify the initial properties of a scrapie isolate, thus questioning the relevance of zoonotic potential for the initial sheep-derived isolate. The same isolate had also induced disease into squirrel monkeys (new-world monkey)9. A second historical observation reported that a cynomolgus macaque developed TSE 6 years post-inoculation with brain homogenate from a scrapie-infected Suffolk ewe (derived from USA), whereas a rhesus macaque and a chimpanzee exposed to the same inoculum remained healthy 9 years post-exposure1. This inoculum also induced TSE in squirrel monkeys after 4 passages in mice. Other scrapie transmission attempts in macaque failed but had more shorter periods of observation in comparison to the current study. Further, it is possible that there are differences in the zoonotic potential of different scrapie strains.

The most striking observation in our study is the extended incubation period of scrapie in the macaque model, which has several implications. Firstly, our observations constitute experimental evidence in favor of the zoonotic potential of c-scrapie, at least for this isolate that has been extensively studied32,33,34,35,36. The cross-species zoonotic ability of this isolate should be confirmed by performing duplicate intracerebral exposures and assessing the transmissibility by the oral route (a successful transmission of prion strains through the intracerebral route may not necessarily indicate the potential for oral transmission37). However, such confirmatory experiments may require more than one decade, which is hardly compatible with current general management and support of scientific projects; thus this study should be rather considered as a case report.

Secondly, transmission of c-BSE to primates occurred within 8 years post exposure for the lowest doses able to transmit the disease (the survival period after inoculation is inversely proportional to the initial amount of infectious inoculum). The occurrence of scrapie 10 years after exposure to a high dose (25 mg) of scrapie-infected sheep brain suggests that the macaque has a higher species barrier for sheep c-scrapie than c-BSE, although it is notable that previous studies based on in vitro conversion of PrP suggested that BSE and scrapie prions would have a similar conversion potential for human PrP38.

Thirdly, prion diseases typically have longer incubation periods after oral exposure than after intracerebral inoculations: since humans can develop Kuru 47 years after oral exposure39, an incubation time of several decades after oral exposure to scrapie would therefore be expected, leading the disease to occur in older adults, i.e. the peak age for cases considered to be sporadic disease, and making a distinction between scrapie-associated and truly sporadic disease extremely difficult to appreciate.

Fourthly, epidemiologic evidence is necessary to confirm the zoonotic potential of an animal disease suggested by experimental studies. A relatively short incubation period and a peculiar epidemiological situation (e.g., all the first vCJD cases occurring in the country with the most important ongoing c-BSE epizootic) led to a high degree of suspicion that c-BSE was the cause of vCJD. Sporadic CJD are considered spontaneous diseases with an almost stable and constant worldwide prevalence (0.5–2 cases per million inhabitants per year), and previous epidemiological studies were unable to draw a link between sCJD and classical scrapie6,7,40,41, even though external causes were hypothesized to explain the occurrence of some sCJD clusters42,43,44. However, extended incubation periods exceeding several decades would impair the predictive values of epidemiological surveillance for prion diseases, already weakened by a limited prevalence of prion diseases and the multiplicity of isolates gathered under the phenotypes of “scrapie” and “sporadic CJD”.

Fifthly, considering this 10 year-long incubation period, together with both laboratory and epidemiological evidence of decade or longer intervals between infection and clinical onset of disease, no premature conclusions should be drawn from negative transmission studies in cynomolgus macaques with less than a decade of observation, as in the aforementioned historical transmission studies of scrapie to primates1,8,9. Our observations and those of others45,46 to date are unable to provide definitive evidence regarding the zoonotic potential of CWD, atypical/Nor98 scrapie or H-type BSE. The extended incubation period of the scrapie-affected macaque in the current study also underscores the limitations of rodent models expressing human PrP for assessing the zoonotic potential of some prion diseases since their lifespan remains limited to approximately two years21,47,48. This point is illustrated by the fact that the recently reported transmission of scrapie to humanized mice was not associated with clinical signs for up to 750 days and occurred in an extreme minority of mice with only a marginal increase in attack rate upon second passage13. The low attack rate in these studies is certainly linked to the limited lifespan of mice compared to the very long periods of observation necessary to demonstrate the development of scrapie. Alternatively, one could estimate that a successful second passage is the result of strain adaptation to the species barrier, thus poorly relevant of the real zoonotic potential of the original scrapie isolate of sheep origin49. The development of scrapie in this primate after an incubation period compatible with its lifespan complements the study conducted in transgenic (humanized) mice; taken together these studies suggest that some isolates of sheep scrapie can promote misfolding of the human prion protein and that scrapie can develop within the lifespan of some primate species.

In addition to previous studies on scrapie transmission to primate1,8,9 and the recently published study on transgenic humanized mice13, our results constitute new evidence for recommending that the potential risk of scrapie for human health should not be dismissed. Indeed, human PrP transgenic mice and primates are the most relevant models for investigating the human transmission barrier. To what extent such models are informative for measuring the zoonotic potential of an animal TSE under field exposure conditions is unknown. During the past decades, many protective measures have been successfully implemented to protect cattle from the spread of c-BSE, and some of these measures have been extended to sheep and goats to protect from scrapie according to the principle of precaution. Since cases of c-BSE have greatly reduced in number, those protective measures are currently being challenged and relaxed in the absence of other known zoonotic animal prion disease. We recommend that risk managers should be aware of the long term potential risk to human health of at least certain scrapie isolates, notably for lymphotropic strains like the classical scrapie strain used in the current study. Relatively high amounts of infectivity in peripheral lymphoid organs in animals infected with these strains could lead to contamination of food products produced for human consumption. Efforts should also be maintained to further assess the zoonotic potential of other animal prion strains in long-term studies, notably lymphotropic strains with high prevalence like CWD, which is spreading across North America, and atypical/Nor98 scrapie (Nor98)50 that was first detected in the past two decades and now represents approximately half of all reported cases of prion diseases in small ruminants worldwide, including territories previously considered as scrapie free. Even if the prevailing view is that sporadic CJD is due to the spontaneous formation of CJD prions, it remains possible that its apparent sporadic nature may, at least in part, result from our limited capacity to identify an environmental origin.




O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations

Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods.

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD) disease in human. To date, BSE agent is the only recognized zoonotic prion. Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that have been circulating for centuries in farmed ruminants there is no apparent epidemiological link between exposure to ruminant products and the occurrence of other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD). However, the zoonotic potential of the diversity of circulating TSE agents has never been systematically assessed. The major issue in experimental assessment of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the biological phenomenon that limits TSE agents’ propagation from a species to another. In the last decade, mice genetically engineered to express normal forms of the human prion protein has proved essential in studying human prions pathogenesis and modeling the capacity of TSEs to cross the human species barrier.
To assess the zoonotic potential of prions circulating in farmed ruminants, we study their transmission ability in transgenic mice expressing human PrPC (HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC (129Met or 129Val) are used to determine the role of the Met129Val dimorphism in susceptibility/resistance to the different agents.
These transmission experiments confirm the ability of BSE prions to propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be susceptible to BSE in sheep or goat to a greater degree than the BSE agent in cattle and that these agents can convey molecular properties and neuropathological indistinguishable from vCJD. However homozygous 129V mice are resistant to all tested BSE derived prions independently of the originating species suggesting a higher transmission barrier for 129V-PrP variant.
Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice. 
Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion. 
These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions. 
 why do we not want to do TSE transmission studies on chimpanzees $
5. A positive result from a chimpanzee challenged severly would likely create alarm in some circles even if the result could not be interpreted for man. I have a view that all these agents could be transmitted provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to retain that hypothesis.

 Title: Transmission of scrapie prions to primate after an extended silent incubation period) 
*** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS. 
*** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated. 
*** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains.

Oral transmission of CWD into Cynomolgus macaques: signs of atypical disease, prion conversion and infectivity in macaques and bio-assayed transgenic mice 

Hermann M. Schatzl, Samia Hannaoui, Yo-Ching Cheng, Sabine Gilch (Calgary Prion Research Unit, University of Calgary, Calgary, Canada) Michael Beekes (RKI Berlin), Walter Schulz-Schaeffer (University of Homburg/Saar, Germany), Christiane Stahl-Hennig (German Primate Center) & Stefanie Czub (CFIA Lethbridge). 

To date, BSE is the only example of interspecies transmission of an animal prion disease into humans. The potential zoonotic transmission of CWD is an alarming issue and was addressed by many groups using a variety of in vitro and in vivo experimental systems. Evidence from these studies indicated a substantial, if not absolute, species barrier, aligning with the absence of epidemiological evidence suggesting transmission into humans. Studies in non-human primates were not conclusive so far, with oral transmission into new-world monkeys and no transmission into old-world monkeys. 

Our consortium has challenged 18 Cynomolgus macaques with characterized CWD material, focusing on oral transmission with muscle tissue. Some macaques have orally received a total of 5 kg of muscle material over a period of 2 years. After 5-7 years of incubation time some animals showed clinical symptoms indicative of prion disease, and prion neuropathology and PrPSc deposition were detected in spinal cord and brain of some euthanized animals. PrPSc in immunoblot was weakly detected in some spinal cord materials and various tissues tested positive in RT-QuIC, including lymph node and spleen homogenates. To prove prion infectivity in the macaque tissues, we have intracerebrally inoculated 2 lines of transgenic mice, expressing either elk or human PrP. At least 3 TgElk mice, receiving tissues from 2 different macaques, showed clinical signs of a progressive prion disease and brains were positive in immunoblot and RT-QuIC. Tissues (brain, spinal cord and spleen) from these and pre-clinical mice are currently tested using various read-outs and by second passage in mice. Transgenic mice expressing human PrP were so far negative for clear clinical prion disease (some mice >300 days p.i.). In parallel, the same macaque materials are inoculated into bank voles. 

Taken together, there is strong evidence of transmissibility of CWD orally into macaques and from macaque tissues into transgenic mouse models, although with an incomplete attack rate. The clinical and pathological presentation in macaques was mostly atypical, with a strong emphasis on spinal cord pathology. Our ongoing studies will show whether the transmission of CWD into macaques and passage in transgenic mice represents a form of non-adaptive prion amplification, and whether macaque-adapted prions have the potential to infect mice expressing human PrP. The notion that CWD can be transmitted orally into both new-world and old-world non-human primates asks for a careful reevaluation of the zoonotic risk of CWD.

This is a progress report of a project which started in 2009. 21 cynomolgus macaques were challenged with characterized CWD material from white-tailed deer (WTD) or elk by intracerebral (ic), oral, and skin exposure routes. Additional blood transfusion experiments are supposed to assess the CWD contamination risk of human blood product. Challenge materials originated from symptomatic cervids for ic, skin scarification and partially per oral routes (WTD brain). Challenge material for feeding of muscle derived from preclinical WTD and from preclinical macaques for blood transfusion experiments. We have confirmed that the CWD challenge material contained at least two different CWD agents (brain material) as well as CWD prions in muscle-associated nerves. Here we present first data on a group of animals either challenged ic with steel wires or per orally and sacrificed with incubation times ranging from 4.5 to 6.9 years at postmortem. Three animals displayed signs of mild clinical disease, including anxiety, apathy, ataxia and/or tremor. In four animals wasting was observed, two of those had confirmed diabetes. All animals have variable signs of prion neuropathology in spinal cords and brains and by supersensitive IHC, reaction was detected in spinal cord segments of all animals. Protein misfolding cyclic amplification (PMCA), real-time quaking-induced conversion (RT-QuiC) and PET-blot assays to further substantiate these findings are on the way, as well as bioassays in bank voles and transgenic mice. At present, a total of 10 animals are sacrificed and read-outs are ongoing. Preclinical incubation of the remaining macaques covers a range from 6.4 to 7.10 years. Based on the species barrier and an incubation time of > 5 years for BSE in macaques and about 10 years for scrapie in macaques, we expected an onset of clinical disease beyond 6 years post inoculation.

***We have concluded that the human protein has a region that confers unusual susceptibility to conversion by CWD prions. CWD is unique among prion diseases in its rapid spread in natural populations. BSE prions are essentially unaltered upon passage to a new species, while CWD adapts to the new species. This adaptation has consequences for surveillance of humans exposed to CWD.

CDC CWD 2018 TRANSMISSION 


*** The potential impact of prion diseases on human health was greatly magnified by the recognition that interspecies transfer of BSE to humans by beef ingestion resulted in vCJD. While changes in animal feed constituents and slaughter practices appear to have curtailed vCJD, there is concern that CWD of free-ranging deer and elk in the U.S. might also cross the species barrier. Thus, consuming venison could be a source of human prion disease. Whether BSE and CWD represent interspecies scrapie transfer or are newly arisen prion diseases is unknown. Therefore, the possibility of transmission of prion disease through other food animals cannot be ruled out. There is evidence that vCJD can be transmitted through blood transfusion. There is likely a pool of unknown size of asymptomatic individuals infected with vCJD, and there may be asymptomatic individuals infected with the CWD equivalent. These circumstances represent a potential threat to blood, blood products, and plasma supplies.

Cervid to human prion transmission

Kong, Qingzhong

Case Western Reserve University, Cleveland, OH, United States

Abstract

Prion disease is transmissible and invariably fatal. Chronic wasting disease (CWD) is the prion disease affecting deer, elk and moose, and it is a widespread and expanding epidemic affecting 22 US States and 2 Canadian provinces so far. CWD poses the most serious zoonotic prion transmission risks in North America because of huge venison consumption (>6 million deer/elk hunted and consumed annually in the USA alone), significant prion infectivity in muscles and other tissues/fluids from CWD-affected cervids, and usually high levels of individual exposure to CWD resulting from consumption of the affected animal among often just family and friends. However, we still do not know whether CWD prions can infect humans in the brain or peripheral tissues or whether clinical/asymptomatic CWD zoonosis has already occurred, and we have no essays to reliably detect CWD infection in humans. We hypothesize that:

(1) The classic CWD prion strain can infect humans at low levels in the brain and peripheral lymphoid tissues;

(2) The cervid-to-human transmission barrier is dependent on the cervid prion strain and influenced by the host (human) prion protein (PrP) primary sequence;

(3) Reliable essays can be established to detect CWD infection in humans;and 


*** (4) CWD transmission to humans has already occurred.

We will test these hypotheses in 4 Aims using transgenic (Tg) mouse models and complementary in vitro approaches.

Aim 1 will prove that the classical CWD strain may infect humans in brain or peripheral lymphoid tissues at low levels by conducting systemic bioassays in a set of "humanized" Tg mouse lines expressing common human PrP variants using a number of CWD isolates at varying doses and routes. Experimental "human CWD" samples will also be generated for Aim 3.

Aim 2 will test the hypothesis that the cervid-to-human prion transmission barrier is dependent on prion strain and influenced by the host (human) PrP sequence by examining and comparing the transmission efficiency and phenotypes of several atypical/unusual CWD isolates/strains as well as a few prion strains from other species that have adapted to cervid PrP sequence, utilizing the same panel of humanized Tg mouse lines as in Aim 1.
Aim 3 will establish reliable essays for detection and surveillance of CWD infection in humans by examining in details the clinical, pathological, biochemical and in vitro seeding properties of existing and future experimental "human CWD" samples generated from Aims 1-2 and compare them with those of common sporadic human Creutzfeldt-Jakob disease (sCJD) prions.

Aim 4 will attempt to detect clinical CWD-affected human cases by examining a significant number of brain samples from prion-affected human subjects in the USA and Canada who have consumed venison from CWD-endemic areas utilizing the criteria and essays established in Aim 3. The findings from this proposal will greatly advance our understandings on the potential and characteristics of cervid prion transmission in humans, establish reliable essays for CWD zoonosis and potentially discover the first case(s) of CWD infection in humans. 

Public Health Relevance There are significant and increasing human exposure to cervid prions because chronic wasting disease (CWD, a widespread and highly infectious prion disease among deer and elk in North America) continues spreading and consumption of venison remains popular, but our understanding on cervid-to-human prion transmission is still very limited, raising public health concerns. This proposal aims to define the zoonotic risks of cervid prions and set up and apply essays to detect CWD zoonosis using mouse models and in vitro methods. The findings will greatly expand our knowledge on the potentials and characteristics of cervid prion transmission in humans, establish reliable essays for such infections and may discover the first case(s) of CWD infection in humans.

 Prion Infectivity in Fat of Deer with Chronic Wasting Disease 
Brent Race#, Kimberly Meade-White#, Richard Race and Bruce Chesebro* + Author Affiliations
In mice, prion infectivity was recently detected in fat. Since ruminant fat is consumed by humans and fed to animals, we determined infectivity titers in fat from two CWD-infected deer. Deer fat devoid of muscle contained low levels of CWD infectivity and might be a risk factor for prion infection of other species.
Prions in Skeletal Muscles of Deer with Chronic Wasting Disease 
Here bioassays in transgenic mice expressing cervid prion protein revealed the presence of infectious prions in skeletal muscles of CWD-infected deer, demonstrating that humans consuming or handling meat from CWD-infected deer are at risk to prion exposure.

Dear Mr Elmhirst,

CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT

Thank you for your recent letter concerning the publication of the third annual report from the CJD Surveillance Unit. I am sorry that you are dissatisfied with the way in which this report was published.

The Surveillance Unit is a completely independant outside body and the Department of Health is committed to publishing their reports as soon as they become available. In the circumstances it is not the practice to circulate the report for comment since the findings of the report would not be amended. In future we can ensure that the British Deer Farmers Association receives a copy of the report in advance of publication.

The Chief Medical Officer has undertaken to keep the public fully informed of the results of any research in respect of CJD. This report was entirely the work of the unit and was produced completely independantly of the the Department.

The statistical results reqarding the consumption of venison was put into perspective in the body of the report and was not mentioned at all in the press release. Media attention regarding this report was low key but gave a realistic presentation of the statistical findings of the Unit. This approach to publication was successful in that consumption of venison was highlighted only once by the media ie. in the News at one television proqramme.

I believe that a further statement about the report, or indeed statistical links between CJD and consumption of venison, would increase, and quite possibly give damaging credence, to the whole issue. From the low key media reports of which I am aware it seems unlikely that venison consumption will suffer adversely, if at all.


*** The association between venison eating and risk of CJD shows similar pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK OF CJD (p = 0.04). ***

*** The association between venison eating and risk of CJD shows similar pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK OF CJD (p = 0.04). ***

*** The association between venison eating and risk of CJD shows similar pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK OF CJD (p = 0.04). ***

There is some evidence that risk of CJD INCREASES WITH INCREASING FREQUENCY OF LAMB EATING (p = 0.02).

The evidence for such an association between beef eating and CJD is weaker (p = 0.14). When only controls for whom a relative was interviewed are included, this evidence becomes a little STRONGER (p = 0.08).

snip...

It was found that when veal was included in the model with another exposure, the association between veal and CJD remained statistically significant (p = < 0.05 for all exposures), while the other exposures ceased to be statistically significant (p = > 0.05).

snip...

In conclusion, an analysis of dietary histories revealed statistical associations between various meats/animal products and INCREASED RISK OF CJD. When some account was taken of possible confounding, the association between VEAL EATING AND RISK OF CJD EMERGED AS THE STRONGEST OF THESE ASSOCIATIONS STATISTICALLY. ...

snip...

In the study in the USA, a range of foodstuffs were associated with an increased risk of CJD, including liver consumption which was associated with an apparent SIX-FOLD INCREASE IN THE RISK OF CJD. By comparing the data from 3 studies in relation to this particular dietary factor, the risk of liver consumption became non-significant with an odds ratio of 1.2 (PERSONAL COMMUNICATION, PROFESSOR A. HOFMAN. ERASMUS UNIVERSITY, ROTTERDAM). (???...TSS)

CHRONIC WASTING DISEASE CWD TSE PRION IS THE USA AND NORTH AMERICA'S MAD COW DISEASE.

BUT CWD TSE PRION IN CERVIDS IS A DIFFERENT BEAST, THE COVER UP THERE, USDA INC COULD NOT CONTAIN.

SPORADIC CJD IS 85%+ OF ALL HUMAN TSE PRION DISEASE.

SPORADIC CJD HAS NOW BEEN LINKED TO TYPICAL AND ATYPICAL BSE, SCRAPIE, AND CWD.

SPORADIC/SPONTANEOUS TSE HAS NEVER BEEN PROVEN.

***Moreover, sporadic disease has never been observed in breeding colonies or primate research laboratories, most notably among hundreds of animals over several decades of study at the National Institutes of Health25, and in nearly twenty older animals continuously housed in our own facility.***


CDC CWD TSE PRION UPDATE USA JANUARY 2018

As of January 2018, CWD in free-ranging deer, elk and/or moose has been reported in at least 22 states in the continental United States, as well as two provinces in Canada. In addition, CWD has been reported in reindeer and moose in Norway, and a small number of imported cases have been reported in South Korea. The disease has also been found in farmed deer and elk. CWD was first identified in captive deer in the late 1960s in Colorado and in wild deer in 1981. By the 1990s, it had been reported in surrounding areas in northern Colorado and southern Wyoming. Since 2000, the area known to be affected by CWD in free-ranging animals has increased to at least 22 states, including states in the Midwest, Southwest, and limited areas on the East Coast.. It is possible that CWD may also occur in other states without strong animal surveillance systems, but that cases haven’t been detected yet. Once CWD is established in an area, the risk can remain for a long time in the environment. The affected areas are likely to continue to expand. Nationwide, the overall occurrence of CWD in free-ranging deer and elk is relatively low. However, in several locations where the disease is established, infection rates may exceed 10 percent (1 in 10), and localized infection rates of more than 25 percent (1 in 4) have been reported. The infection rates among some captive deer can be much higher, with a rate of 79% (nearly 4 in 5) reported from at least one captive herd. As of January 2018, there were 186 counties in 22 states with reported CWD in free-ranging cervids.

Transmission Studies

Mule deer transmissions of CWD were by intracerebral inoculation and compared with natural cases {the following was written but with a single line marked through it ''first passage (by this route)}...TSS

resulted in a more rapidly progressive clinical disease with repeated episodes of synocopy ending in coma. One control animal became affected, it is believed through contamination of inoculum (?saline). Further CWD transmissions were carried out by Dick Marsh into ferret, mink and squirrel monkey. Transmission occurred in ALL of these species with the shortest incubation period in the ferret.

Dear Sir/Madam,
In the Archives of Neurology you quoted (the abstract of which was attached to your email), we did not say CWD in humans will present like variant CJD. That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

8. Even though human TSE‐exposure risk through consumption of game from European cervids can be assumed to be minor, if at all existing, no final conclusion can be drawn due to the overall lack of scientific data. In particular the US data do not clearly exclude the possibility of human (sporadic or familial) TSE development due to consumption of venison. The Working Group thus recognizes a potential risk to consumers if a TSE would be present in European cervids. It might be prudent considering appropriate measures to reduce such a risk, e.g. excluding tissues such as CNS and lymphoid tissues from the human food chain, which would greatly reduce any potential risk for consumers. However, it is stressed that currently, no data regarding a risk of TSE infections from cervid products are available. 

snip... 

The tissue distribution of infectivity in CWD‐infected cervids is now known to extend beyond CNS and lymphoid tissues. While the removal of these specific tissues from the food chain would reduce human dietary exposure to infectivity, exclusion from the food chain of the whole carcass of any infected animal would be required to eliminate human dietary exposure. 


zoonosis zoonotic cervid tse prion cwd to humans, preparing for the storm 

***An alternative to modeling the species barrier is the cell-free conversion assay which points to CWD as the animal prion disease with the greatest zoonotic potential, after (and very much less than) BSE.116*** 




To date there is no direct evidence that CWD has been or can be transmitted from animals to humans. 


However, initial findings from a laboratory research project funded by the Alberta Prion Research Institute (APRI) and Alberta Livestock Meat Agency (ALMA), and led by a Canadian Food Inspection Agency (CFIA) scientist indicate that CWD has been transmitted to cynomolgus macaques (the non-human primate species most closely related to humans that may be used in research), through both the intracranial and oral routes of exposure. 

Both infected brain and muscle tissues were found to transmit disease. 

Health Canada’s Health Products and Food Branch (HPFB) was asked to consider the impact of these findings on the Branch’s current position on CWD in health products and foods. 

Summary and Recommendation: 

snip...

Health Portfolio partners were recently made aware of initial findings from a research project led by a CFIA scientist that have demonstrated that cynomolgus macaques can be infected via intracranial exposure and oral gavage with CWD infected muscle. 

These findings suggest that CWD, under specific experimental conditions, has the potential to cross the human species barrier, including by enteral feeding of CWD infected muscle. 





> However, to date, no CWD infections have been reported in people. 

key word here is 'reported'. science has shown that CWD in humans will look like sporadic CJD. SO, how can one assume that CWD has not already transmitted to humans? they can't, and it's as simple as that. from all recorded science to date, CWD has already transmitted to humans, and it's being misdiagnosed as sporadic CJD. ...terry 

*** LOOKING FOR CWD IN HUMANS AS nvCJD or as an ATYPICAL CJD, LOOKING IN ALL THE WRONG PLACES $$$ ***

*** These results would seem to suggest that CWD does indeed have zoonotic potential, at least as judged by the compatibility of CWD prions and their human PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests that if zoonotic CWD occurred, it would most likely effect those of the PRNP codon 129-MM genotype and that the PrPres type would be similar to that found in the most common subtype of sCJD (MM1).***

CDC Assesses Potential Human Exposure to Prion Diseases Travel Warning

Public release date: 23-May-2011

Contact: Francesca Costanzo adajmedia@elsevier.com 215-239-3249 Elsevier Health Sciences

CDC assesses potential human exposure to prion diseases Study results reported in the Journal of the American Dietetic Association Philadelphia, PA, May 23, 2011 – Researchers from the Centers for Disease Control and Prevention (CDC) have examined the potential for human exposure to prion diseases, looking at hunting, venison consumption, and travel to areas in which prion diseases have been reported in animals. Three prion diseases in particular – bovine spongiform encephalopathy (BSE or “Mad Cow Disease”), variant Creutzfeldt-Jakob disease (vCJD), and chronic wasting disease (CWD) – were specified in the investigation. The results of this investigation are published in the June issue of the Journal of the American Dietetic Association.

“While prion diseases are rare, they are generally fatal for anyone who becomes infected. More than anything else, the results of this study support the need for continued surveillance of prion diseases,” commented lead investigator Joseph Y. Abrams, MPH, National Center for Emerging and Zoonotic Infectious Diseases, CDC, Atlanta.”But it’s also important that people know the facts about these diseases, especially since this study shows that a good number of people have participated in activities that may expose them to infection-causing agents.”

Although rare, human prion diseases such as CJD may be related to BSE. Prion (proteinaceous infectious particles) diseases are a group of rare brain diseases that affect humans and animals. When a person gets a prion disease, brain function is impaired. This causes memory and personality changes, dementia, and problems with movement. All of these worsen over time. These diseases are invariably fatal. Since these diseases may take years to manifest, knowing the extent of human exposure to possible prion diseases could become important in the event of an outbreak.

CDC investigators evaluated the results of the 2006-2007 population survey conducted by the Foodborne Diseases Active Surveillance Network (FoodNet). This survey collects information on food consumption practices, health outcomes, and demographic characteristics of residents of the participating Emerging Infections Program sites. The survey was conducted in Connecticut, Georgia, Maryland, Minnesota, New Mexico, Oregon, and Tennessee, as well as five counties in the San Francisco Bay area, seven counties in the Greater Denver area, and 34 counties in western and northeastern New York.

Survey participants were asked about behaviors that could be associated with exposure to the agents causing BSE and CWD, including travel to the nine countries considered to be BSE-endemic (United Kingdom, Republic of Ireland, France, Portugal, Switzerland, Italy, the Netherlands, Germany, Spain) and the cumulative length of stay in each of those countries. Respondents were asked if they ever had hunted for deer or elk, and if that hunting had taken place in areas considered to be CWD-endemic (northeastern Colorado, southeastern Wyoming or southwestern Nebraska). They were also asked if they had ever consumed venison, the frequency of consumption, and whether the meat came from the wild.

The proportion of survey respondents who reported travel to at least one of the nine BSE endemic countries since 1980 was 29.5%. Travel to the United Kingdom was reported by 19.4% of respondents, higher than to any other BSE-endemic country. Among those who traveled, the median duration of travel to the United Kingdom (14 days) was longer than that of any other BSE-endemic country. Travelers to the UK were more likely to have spent at least 30 days in the country (24.9%) compared to travelers to any other BSE endemic country. The prevalence and extent of travel to the UK indicate that health concerns in the UK may also become issues for US residents.

The proportion of survey respondents reporting having hunted for deer or elk was 18.5% and 1.2% reported having hunted for deer or elk in CWD-endemic areas. Venison consumption was reported by 67.4% of FoodNet respondents, and 88.6% of those reporting venison consumption had obtained all of their meat from the wild. These findings reinforce the importance of CWD surveillance and control programs for wild deer and elk to reduce human exposure to the CWD agent. Hunters in CWD-endemic areas are advised to take simple precautions such as: avoiding consuming meat from sickly deer or elk, avoiding consuming brain or spinal cord tissues, minimizing the handling of brain and spinal cord tissues, and wearing gloves when field-dressing carcasses.

According to Abrams, “The 2006-2007 FoodNet population survey provides useful information should foodborne prion infection become an increasing public health concern in the future. The data presented describe the prevalence of important behaviors and their associations with demographic characteristics. Surveillance of BSE, CWD, and human prion diseases are critical aspects of addressing the burden of these diseases in animal populations and how that may relate to human health.”

Abstract

The transmission of bovine spongiform encephalopathy (BSE) to human beings and the spread of chronic wasting disease (CWD) among cervids have prompted concerns about zoonotic transmission of prion diseases. Travel to the United Kingdom and other European countries, hunting for deer or elk, and venison consumption could result in the exposure of US residents to the agents that cause BSE and CWD. The Foodborne Diseases Active Surveillance Network 2006-2007 population survey was used to assess the prevalence of these behaviors among residents of 10 catchment areas across the United States. Of 17,372 survey respondents, 19.4% reported travel to the United Kingdom since 1980, and 29.5% reported travel to any of the nine European countries considered to be BSE-endemic since 1980. The proportion of respondents who had ever hunted deer or elk was 18.5%, and 1.2% had hunted deer or elk in a CWD–endemic area. More than two thirds (67.4%) reported having ever eaten deer or elk meat. Respondents who traveled spent more time in the United Kingdom (median 14 days) than in any other BSE-endemic country. Of the 11,635 respondents who had consumed venison, 59.8% ate venison at most one to two times during their year of highest consumption, and 88.6% had obtained all of their meat from the wild. The survey results were useful in determining the prevalence and frequency of behaviors that could be important factors for foodborne prion transmission.

TEXAS MAD COW DISEASE CASES

Statement of Gov. Rick Perry on BSE Announcement

Thursday, June 30, 2005 • Press Release

AUSTIN – Gov. Rick Perry issued the following statement today on the announcement by the U.S. Department of Agriculture that a cow recently tested for Bovine Spongiform Encephalopathy – commonly known as mad cow disease – is from a Texas herd.

“I want to urge calm and reassure the public that they can have the highest confidence in our beef supply, and the safeguards we have in place to protect the public from the spread of BSE. There is not, nor has there ever been, a known instance of BSE contaminating the food supply in Texas or anywhere else in the United States.

The animal in question was not processed into food or any other product. Texans can be sure that the beef they buy at their local supermarkets or restaurants is as safe today as it was yesterday, and I encourage Texans to continue to enjoy Texas beef products.”

Section 2. Testing Protocols and Quality Assurance Controls

In November 2004, USDA announced that its rapid screening test, Bio-Rad Enzyme Linked Immunosorbent Assay (ELISA), produced an inconclusive BSE test result as part of its enhanced BSE surveillance program. The ELISA rapid screening test performed at a BSE contract laboratory produced three high positive reactive results.40 As required,41 the contract laboratory forwarded the inconclusive sample to the APHIS National Veterinary Services Laboratories (NVSL) for confirmatory testing. NVSL repeated the ELISA testing and again produced three high positive reactive results.42 In accordance with its established protocol, NVSL ran its confirmatory test, an immunohistochemistry (IHC) test, which was interpreted as negative for BSE. In addition, NVSL performed a histological43 examination of the tissue and did not detect lesions44 consistent with BSE.

Faced with conflicting results, NVSL scientists recommended additional testing to resolve the discrepancy but APHIS headquarters officials concluded no further testing was necessary because testing protocols were followed. In our discussions with APHIS officials, they justified their decision not to do additional testing because the IHC is internationally recognized as the "gold standard." Also, they believed that conducting additional tests would undermine confidence in USDA’s established testing protocols.

USDA orders silence on mad cow in Texas

Susan Combs by no means has public and consumer health at heart while she is protecting the cattle industry. She is oblivious to mad cow disease. Her soul purpose is to protect the cattle industry at all cost, including my mothers life (DOD 12/14/97), or maybe one of your family members from any strain of mad cow disease in TEXAS. SHE helped cover-up mad cow disease in TEXAS both on that inconclusive that was positive so many times it will make your head spin. PLUS, the other mad cow in TEXAS they rendered without testing at all, that came from the top out of Austin. THEY should be tried for murder. corporate homicide is what i call it. they knew for years, but kept on keeping on.

Subject: USDA OIG SEMIANNUAL REPORT TO CONGRESS FY 2007 1st Half (bogus BSE sampling FROM HEALTHY USDA CATTLE)

Date: June 21, 2007 at 2:49 pm PST

Owner and Corporation Plead Guilty to Defrauding Bovine Spongiform Encephalopathy (BSE) Surveillance Program

An Arizona meat processing company and its owner pled guilty in February 2007 to charges of theft of Government funds, mail fraud, and wire fraud. The owner and his company defrauded the BSE Surveillance Program when they falsified BSE Surveillance Data Collection Forms and then submitted payment requests to USDA for the services. In addition to the targeted sample population (those cattle that were more than 30 months old or had other risk factors for BSE), the owner submitted to USDA, or caused to be submitted, BSE obex (brain stem) samples from healthy USDA-inspected cattle. As a result, the owner fraudulently received approximately $390,000. Sentencing is scheduled for May 2007.

Texas BSE Investigation Final Epidemiology Report August 2005

Executive Summary

In June 2005, an inconclusive bovine spongiform encephalopathy (BSE) sample from November 2004, that had originally been classified as negative on the immunohistochemistry test, was confirmed positive on SAF immunoblot (Western blot). The U.S. Department of Agriculture (USDA) identified the herd of origin for the index cow in Texas; that identification was confirmed by DNA analysis. USDA, in close cooperation with the Texas Animal Health Commission (TAHC), established an incident command post (ICP) and began response activities according to USDA’s BSE Response Plan of September 2004. Response personnel removed at-risk cattle and cattle of interest (COI) from the index herd, euthanized them, and tested them for BSE; all were negative. USDA and the State extensively traced all at-risk cattle and COI that left the index herd. The majority of these animals entered rendering and/or slaughter channels well before the investigation began. USDA’s response to the Texas finding was thorough and effective.

Background of the Investigation

On June 10, 2005, USDA announced that the November 2004 inconclusive BSE sample tested positive on SAF immunoblot. The SAF immunoblot was run at USDA’s National Animal Disease Center (NADC) upon the recommendation of USDA’s Office of the Inspector General. Samples were sent to a World Organization for Animal Health (OIE) reference laboratory for BSE in Weybridge, England, for confirmatory tests. Farm A, located in Texas, was the suspected farm of origin for the index cow and was placed under hold order on June 20, 2005 pending confirmation of the positive results and DNA analysis of the herd. Weybridge confirmed the BSE positive on June 24, 2005. The carcass of the index cow had been disposed of by incineration in November 2004.

State-Federal Team Responds to Texas BSE Case

The US Department of Agriculture announced June 29 that genetic testing has verified that an aged cow that tested positive for Bovine Spongiform Encephalopathy or BSE originated from a Texas beef cattle herd. Tissues for laboratory testing were initially collected from the animal in November 2004, and the carcass was incinerated and did not enter the human food, animal feed or fertilizer supply system. While tests in November indicated the animal did not have BSE, retesting in England in June confirmed the animal had the disease. The Texas Animal Health Commission (TAHC), the state’s livestock and poultry health regulatory agency, and USDA have jointly assigned a state-federal team to conduct the epidemiological investigation and response.

“The TAHC and US Department of Agriculture’s Veterinary Services are working with a complement of experts from federal and state animal health, food safety, public health and feed regulatory agencies to ensure the continued safety and wholesomeness of our meat supply,” said Dr. Bob Hillman, Texas state veterinarian and executive director of the TAHC, the state’s livestock and poultry health regulatory agency. “Epidemiological investigations are thorough and focus on verifying the herd of origin, and when, where and how the animal and potentially, any herd mates, were exposed to the abnormal prion, or disease agent, that causes BSE. Additionally, epidemiology investigations trace the infected animal’s movement and herd mates. Animals potentially exposed to the disease will be depopulated, with proper disposal. The animals will not be introduced into the human or animal food chain.”

The USDA’s BSE testing protocol requires testing of emaciated or injured cattle, cattle that exhibit central nervous system disorder, cattle unable to rise or to walk normally, and cattle that die of unknown causes. Since June 1, 2004, brain tissue samples from more than 394,000 cattle have been tested in the U.S. and were negative for BSE. Of those, 38,320 were tested in Texas, Dr. Hillman noted. BSE surveillance has been conducted in the U.S. since l990.

The U.S. has taken preventive measures against the introduction of BSE since l989, when prohibitions were placed on cattle and other ruminants from BSE-affected countries, noted Dr. Hillman. In 1997, the importation ban was extended to all of Europe.

Dr. Hillman said the U.S. Food and Drug Administration (FDA) in 1997 banned the use of ruminant-derived protein (from animals such as cattle and sheep) in feed for cattle and other ruminants. There is no evidence that BSE spreads from live animal to animal in the herd, but cattle can be exposed by eating feed that contains rendered protein from infected animals. “These measures taken by the USDA and the FDA are safeguards that work to protect livestock, and ultimately, our meat supply,” he said.

Second BSE case occurred in Texas, USDA says Jun 30, 2005 (CIDRAP News) – The United States' second case of bovine spongiform encephalopathy (BSE) was in a 12-year-old cow that came from a Texas herd and would have been made into pet food if it hadn't been flagged for BSE testing, federal officials announced yesterday evening.

US Department of Agriculture (USDA) officials said the cow was to be processed at a pet food plant in Waco, Tex., when it was diverted for testing because it couldn't walk. Officials didn't name the plant or say exactly where the cow came from. But an Associated Press (AP) report today identified the plant as Champion Pet Food in Waco and said the cow was already dead when brought there last November.

"The source herd is now under a hold order as we identify animals of interest within the herd," USDA Chief Veterinarian John Clifford said in a prepared statement. Investigators will look for cattle born within a year before or after the BSE-infected cow and any of the cow's offspring born within the past 2 years, he explained.

"If the age of the animal cannot be pinpointed, then we may expand our inquiry to include all animals in this herd before the feed ban went into place in 1997," Clifford said. To prevent BSE, the government banned putting cattle protein into cattle feed in August 1997.

The infected cow was incinerated, and no parts were used in human food or animal feed, according to the USDA. "The safety of our food supply is not in question," Clifford stated.

Because of the cow's age, the USDA suspects it became infected by eating contaminated feed before the government ban began in 1997. The USDA and the Food and Drug Administration (FDA) will try to trace the source herd's feed history, officials said.

The FDA will also check whether firms that may have processed meat-and-bone meal from animals from that herd have complied with the 1997 feed ban, Dr. Steve Sundlof, director of the FDA's Center for Veterinary Medicine, said at a news conference last night.

The Texas case is the first US BSE case in a native-born animal; Clifford said the cow lived on one farm all its life. The previous US case, found in December 2003, involved a Canadian-born dairy cow in Washington state.

An initial screening test on the Texas cow last November was inconclusive, and two confirmatory immunohistochemistry tests were negative. But early this month the USDA's inspector general ordered a Western blot test, which came back positive. Further confirmatory tests at an international reference lab in Britain were also positive, prompting the USDA to announce the findings last week.

The USDA waited for the results of DNA tests before announcing that the infected cow came from Texas. The step was necessary because parts of the infected cow were stored with those of four other cattle, causing some uncertainty, officials said.

"We felt that we had the correct herd; we wanted to identify that appropriately with DNA," Clifford said at the news conference. Investigators analyzed DNA from the infected animal and then looked for relatives in the presumed source herd by analyzing DNA from members of the herd, he said. The investigation turned up two cattle that are related to the infected cow, he added.

The AP report said Champion Pet Food is under contract to take samples from animals in poor health. The company's owner, Benjy Bauer, told the AP that his workers took samples from the cow and sent them to the Texas Veterinary Diagnostic Laboratory at Texas A&M University. The lab is one of several the USDA uses to screen cattle for BSE, the story said.

THE USDA JUNE 2004 ENHANCED BSE SURVEILLANCE PROGRAM WAS TERRIBLY FLAWED ;

CDC DR. PAUL BROWN TSE EXPERT COMMENTS 2006

In an article today for United Press International, science reporter Steve Mitchell writes:

Analysis: What that mad cow means

By STEVE MITCHELL UPI Senior Medical Correspondent

WASHINGTON, March 15 (UPI) -- The U.S. Department of Agriculture was quick to assure the public earlier this week that the third case of mad cow disease did not pose a risk to them, but what federal officials have not acknowledged is that this latest case indicates the deadly disease has been circulating in U.S. herds for at least a decade.

The second case, which was detected last year in a Texas cow and which USDA officials were reluctant to verify, was approximately 12 years old.

These two cases (the latest was detected in an Alabama cow) present a picture of the disease having been here for 10 years or so, since it is thought that cows usually contract the disease from contaminated feed they consume as calves. The concern is that humans can contract a fatal, incurable, brain-wasting illness from consuming beef products contaminated with the mad cow pathogen.

"The fact the Texas cow showed up fairly clearly implied the existence of other undetected cases," Dr. Paul Brown, former medical director of the National Institutes of Health's Laboratory for Central Nervous System Studies and an expert on mad cow-like diseases, told United Press International. "The question was, 'How many?' and we still can't answer that."

Brown, who is preparing a scientific paper based on the latest two mad cow cases to estimate the maximum number of infected cows that occurred in the United States, said he has "absolutely no confidence in USDA tests before one year ago" because of the agency's reluctance to retest the Texas cow that initially tested positive.

USDA officials finally retested the cow and confirmed it was infected seven months later, but only at the insistence of the agency's inspector general.

"Everything they did on the Texas cow makes everything they did before 2005 suspect," Brown said.

Despite this, Brown said the U.S. prevalence of mad cow, formally known as bovine spongiform encephalopathy, or BSE, did not significantly threaten human or cattle health.

"Overall, my view is BSE is highly unlikely to pose any important risk either in cattle feed or human feed," he said.

However, Jean Halloran of Consumers Union in Yonkers, N.Y., said consumers should be troubled by the USDA's secrecy and its apparent plan to dramatically cut back the number of mad cow tests it conducts.

"Consumers should be very concerned about how little we know about the USDA's surveillance program and the failure of the USDA to reveal really important details," Halloran told UPI. "Consumers have to be really concerned if they're going to cut back the program," she added.

Last year the USDA tested more than 300,000 animals for the disease, but it has proposed, even in light of a third case, scaling back the program to 40,000 tests annually.

"They seem to be, in terms of actions and policies, taking a lot more seriously the concerns of the cattle industry than the concerns of consumers," Halloran said. "It's really hard to know what it takes to get this administration to take action to protect the public."

The USDA has insisted that the safeguards of a ban on incorporating cow tissue into cattle feed (which is thought to spread the disease) and removal of the most infectious parts of cows, such as the brain and spinal cord, protect consumers. But the agency glosses over the fact that both of these systems have been revealed to be inadequately implemented.

The feed ban, which is enforced by the Food and Drug Administration, has been criticized by the Government Accountability Office in two reports, the most recent coming just last year. The GAO said the FDA's enforcement of the ban continues to have weaknesses that "undermine the nation's firewall against BSE."

USDA documents released last year showed more than 1,000 violations of the regulations requiring the removal of brains and spinal cords in at least 35 states, Puerto Rico and the Virgin Islands, with some plants being cited repeatedly for infractions. In addition, a violation of similar regulations that apply to beef exported to Japan is the reason why Japan closed its borders to U.S. beef in January six weeks after reopening them.

Other experts also question the adequacy of the USDA's surveillance system. The USDA insists the prevalence of mad cow disease is low, but the agency has provided few details of its surveillance program, making it difficult for outside experts to know if the agency's monitoring plan is sufficient.

"It's impossible to judge the adequacy of the surveillance system without having a breakdown of the tested population by age and risk status," Elizabeth Mumford, a veterinarian and BSE expert at Safe Food Solutions in Bern, Switzerland, a company that provides advice on reducing mad cow risk to industry and governments, told UPI.

"Everybody would be happier and more confident and in a sense it might be able to go away a little bit for (the USDA) if they would just publish a breakdown on the tests," Mumford added.

UPI requested detailed records about animals tested under the USDA's surveillance plan via the Freedom of Information Act in May 2004 but nearly two years later has not received any corresponding documents from the agency, despite a federal law requiring agencies to comply within 30 days. This leaves open the question of whether the USDA is withholding the information, does not have the information or is so haphazardly organized that it cannot locate it.

Mumford said the prevalence of the disease in U.S. herds is probably quite low, but there have probably been other cases that have so far gone undetected. "They're only finding a very small fraction of that low prevalence," she said.

Mumford expressed surprise at the lack of concern about the deadly disease from American consumers. "I would expect the U.S. public to be more concerned," she said.

Markus Moser, a molecular biologist and chief executive officer of Prionics, a Swiss firm that manufactures BSE test kits, told UPI one concern is that if people are infected, the mad cow pathogen could become "humanized" or more easily transmitted from person to person.

"Transmission would be much easier, through all kinds of medical procedures" and even through the blood supply, Moser said.

FDA STATEMENT FOR IMMEDIATE RELEASE May 4, 2004 Media Inquiries: 301-827-6242 Consumer Inquiries: 888-INFO-FDA

Statement on Texas Cow With Central Nervous System Symptoms 

On Friday, April 30th, the Food and Drug Administration learned that a cow with central nervous system symptoms had been killed and shipped to a processor for rendering into animal protein for use in animal feed.

FDA, which is responsible for the safety of animal feed, immediately began an investigation. On Friday and throughout the weekend, FDA investigators inspected the slaughterhouse, the rendering facility, the farm where the animal came from, and the processor that initially received the cow from the slaughterhouse.

FDA's investigation showed that the animal in question had already been rendered into "meat and bone meal" (a type of protein animal feed). Over the weekend FDA was able to track down all the implicated material. That material is being held by the firm, which is cooperating fully with FDA.

Cattle with central nervous system symptoms are of particular interest because cattle with bovine spongiform encephalopathy or BSE, also known as "mad cow disease," can exhibit such symptoms. In this case, there is no way now to test for BSE. But even if the cow had BSE, FDA's animal feed rule would prohibit the feeding of its rendered protein to other ruminant animals (e.g., cows, goats, sheep, bison).

FDA is sending a letter to the firm summarizing its findings and informing the firm that FDA will not object to use of this material in swine feed only. If it is not used in swine feed, this material will be destroyed. Pigs have been shown not to be susceptible to BSE. If the firm agrees to use the material for swine feed only, FDA will track the material all the way through the supply chain from the processor to the farm to ensure that the feed is properly monitored and used only as feed for pigs.

To protect the U.S. against BSE, FDA works to keep certain mammalian protein out of animal feed for cattle and other ruminant animals. FDA established its animal feed rule in 1997 after the BSE epidemic in the U.K. showed that the disease spreads by feeding infected ruminant protein to cattle.

Under the current regulation, the material from this Texas cow is not allowed in feed for cattle or other ruminant animals. FDA's action specifying that the material go only into swine feed means also that it will not be fed to poultry.

FDA is committed to protecting the U.S. from BSE and collaborates closely with the U.S. Department of Agriculture on all BSE issues. The animal feed rule provides crucial protection against the spread of BSE, but it is only one of several such firewalls. FDA will soon be improving the animal feed rule, to make this strong system even stronger.

The U.S. Department of Agriculture confirmed June 29 that genetic testing had verified bovine spongiform encephalopathy (mad cow disease) in a 12-year-old cow that was born and raised in a Texas beef cattle herd.

Subsequent epidemiological investigations resulted in the culling and testing of 67 adult animals from the index herd. Bio-Rad tests for BSE were conducted on all 67 animals by the National Veterinary Services Laboratory (NVSL) in Ames, Iowa. All tests were negative.

On July 12, Texas officials lifted the quarantine on the source herd. At press time, USDA's Animal and Plant Health Inspection Service was tracing animals of the same age that had left the ranch.

Timeline

The BSE-positive animal was a Brahman-cross cow born and raised in a single Texas herd. The location of the ranch was not disclosed.

On Nov. 11, 2004, the 12-year-old cow was taken to a Texas auction market. Because of its condition, the cow was sent to Champion Pet Foods in Waco, Texas. The company produces several blends of dog food, primarily for the greyhound industry.

On Nov. 15, the animal arrived dead at Champion. Under procedures established by USDA's intensive surveillance program, a sample was sent to the USDA-approved Texas Veterinary Medical Diagnostic Testing Laboratory (TVMDL) at Texas A&M University.

Between June 1, 2004, and June 1, 2005, TVMDL tested nearly 34,000 samples from Texas, New Mexico, Arkansas and Louisiana. They tested the sample from Champion on Nov. 19 using a Bio-Rad ELISA rapid test for BSE. Initial results were inconclusive.

Because of the inconclusive results, a representative from USDA took the entire carcass to TVMDL where it was incinerated. USDA's Animal and Plant Health Inspection Service (APHIS) began tracing the animal and herd.

The sample was then sent to the National Veterinary Services Laboratory for further testing. Two Immunohistochemistry (IHC) tests were conducted and both were negative for BSE. At that point APHIS stopped their trace.

USDA scientists also ran an additional, experimental IHC "rapid" tissue fixation test for academic purposes. This test has not been approved internationally.

Some abnormalities were noted in the experimental test, but because the two approved tests came back negative, the results were not reported beyond the laboratory.

Monitoring by OIG

USDA's Office of Inspector General (OIG) has been monitoring implementation of the BSE expanded surveillance program and evaluating the following:

* Effectiveness of the surveillance program;

* Performance of BSE laboratories in complying with policies and procedures for conducting tests and reporting results;

* Enforcement of the ban on specified risk materials in meat products;

* Controls to prevent central nervous system tissue in advanced meat recovery products;

* Ante mortem condemnation procedures; and

* Procedures for obtaining brain tissue samples from condemned cattle.

While reviewing voluminous records, OIG auditors noticed conflicting test results on one sample-rapid inconclusive, IHC negative, experimental reactive.

Sample retested

At the recommendation of the Inspector General, the sample was retested during the week of June 5 with a second confirmatory test, the Western Blot. The results were reactive.

USDA scientists then conducted an additional IHC confirmatory test, using different antibodies from the November 2004 test. On Friday, June 10, Secretary of Agriculture Mike Johanns publicly announced the results as a "weak positive."

On June 16 an official with USDA's National Veterinary Services Laboratory hand-carried samples for further testing to the Veterinary Laboratory Agency (VLA) in Weybridge, England. Since 1991, the VLA has been a BSE reference laboratory for the World Organization for Animal Health (OIE).

Experts from the Weybridge lab confirmed the accuracy of the results of USDA's November confirmatory IHC test, concurring that the case could not have been confirmed on the basis of this sample. They also examined the November experimental IHC test and interpreted the results to be positive.

Weybridge also conducted additional tests, including IHC, OIE-prescribed Western Blot, NaTTA Western Blot and Prionics Western Blot tests.

To better understand the conflicting results, USDA also conducted Bio-Rad and IDEXX rapid screening tests, IHC and OIE-prescribed Western Blot. USDA also used DNA sequencing to determine the prion protein gene sequence of the animal.

http://findarticles.com/p/articles/mi_qa5420/is_200508/ai_n21377094

Texas even had a 'secret' test that showed that mad cow positive; experimental IHC test results, because the test was not a validated procedure, and because the two approved IHC tests came back negative, the results were not considered to be of regulatory significance and therefore were not reported beyond the laboratory. . A Western blot test conducted the week of June 5, 2005, returned positive for BSE.

48 hr BSE confirmation turnaround took 7+ months to confirm this case, so the BSE MRR policy could be put into place. ...TSS

U.S. Food and Drug Administration FDA News | Today the Food and Drug Administ…U.S. Food and Drug Administration FDA News

Today the Food and Drug Administration announced the results of tests taken on feed used at a Texas feedlot that was suspected of containing meat and bone meal from other domestic cattle — a violation of FDA’s 1997 prohibition on using ruminant material in feed for other ruminants. Results indicate that a very low level of prohibited material was found in the feed fed to cattle.

FDA has determined that each animal could have consumed, at most and in total, five-and-one-half grams – approximately a quarter ounce — of prohibited material. These animals weigh approximately 600 pounds.

It is important to note that the prohibited material was domestic in origin (therefore not likely to contain infected material because there is no evidence of BSE in U.S. cattle), fed at a very low level, and fed only once. The potential risk of BSE to such cattle is therefore exceedingly low, even if the feed were contaminated.

According to Dr. Bernard Schwetz, FDA’s Acting Principal Deputy Commissioner, “The challenge to regulators and industry is to keep this disease out of the United States. One important defense is to prohibit the use of any ruminant animal materials in feed for other ruminant animals. Combined with other steps, like U.S. Department of Agriculture’s (USDA) ban on the importation of live ruminant animals from affected countries, these steps represent a series of protections, to keep American cattle free of BSE.”

Despite this negligible risk, Purina Mills, Inc., is nonetheless announcing that it is voluntarily purchasing all 1,222 of the animals held in Texas and mistakenly fed the animal feed containing the prohibited material. Therefore, meat from those animals will not enter the human food supply. FDA believes any cattle that did not consume feed containing the prohibited material are unaffected by this incident, and should be handled in the beef supply clearance process as usual.

FDA believes that Purina Mills has behaved responsibly by first reporting the human error that resulted in the misformulation of the animal feed supplement and then by working closely with State and Federal authorities.

This episode indicates that the multi-layered safeguard system put into place is essential for protecting the food supply and that continued vigilance needs to be taken, by all concerned, to ensure these rules are followed routinely.

FDA will continue working with USDA as well as State and local officials to ensure that companies and individuals comply with all laws and regulations designed to protect the U.S. food supply.

Spread of BSE prions in cynomolgus monkeys (Macaca fascicularis) after oral transmission

Edgar Holznagel1, Walter Schulz-Schaeffer2, Barbara Yutzy1, Gerhard Hunsmann3, Johannes Loewer1 1Paul-Ehrlich-Institut, Federal Institute for Sera and Vaccines, Germany; 2Department of Neuropathology, Georg-August University, Göttingen, Germany, 3Department of Virology and Immunology, German Primate Centre, Göttingen, Germany

Background: BSE-infected cynomolgus monkeys represent a relevant animal model to study the pathogenesis of variant Creutzfeldt-Jacob disease (vCJD).

Objectives: To study the spread of BSE prions during the asymptomatic phase of infection in a simian animal model.

Methods: Orally BSE-dosed macaques (n=10) were sacrificed at defined time points during the incubation period and 7 orally BSE-dosed macaques were sacrificed after the onset of clinical signs. Neuronal and non-neuronal tissues were tested for the presence of proteinase-K-resistant prion protein (PrPres) by western immunoblot and by paraffin-embedded tissue (PET) blot technique.

Results: In clinically diseased macaques (5 years p.i. + 6 mo.), PrPres deposits were widely spread in neuronal tissues (including the peripheral sympathetic and parasympathetic nervous system) and in lymphoid tissues including tonsils. In asymptomatic disease carriers, PrPres deposits could be detected in intestinal lymph nodes as early as 1 year p.i., but CNS tissues were negative until 3 – 4 years p.i. Lumbal/sacral segments of the spinal cord and medulla oblongata were PrPres positive as early as 4.1 years p.i., whereas sympathetic trunk and all thoracic/cervical segments of the spinal cord were still negative for PrPres. However, tonsil samples were negative in all asymptomatic cases.

Discussion: There is evidence for an early spread of BSE to the CNS via autonomic fibres of the splanchnic and vagus nerves indicating that trans-synaptical spread may be a time-limiting factor for neuroinvasion. Tonsils were predominantly negative during the main part of the incubation period indicating that epidemiological vCJD screening results based on the detection of PrPres in tonsil biopsies may mostly tend to underestimate the prevalence of vCJD among humans.

Experimental BSE Infection of Non-human Primates: Efficacy of the Oral Route

Background:

In 2001, a study was initiated in primates to assess the risk for humans to contract BSE through contaminated food. For this purpose, BSE brain was titrated in cynomolgus monkeys.

Aims:

The primary objective is the determination of the minimal infectious dose (MID50) for oral exposure to BSE in a simian model, and, by in doing this, to assess the risk for humans. Secondly, we aimed at examining the course of the disease to identify possible biomarkers.

Methods:

Groups with six monkeys each were orally dosed with lowering amounts of BSE brain: 16g, 5g, 0.5g, 0.05g, and 0.005g. In a second titration study, animals were intracerebrally (i.c.) dosed (50, 5, 0.5, 0.05, and 0.005 mg).

Results:

In an ongoing study, a considerable number of high-dosed macaques already developed simian vCJD upon oral or intracerebral exposure or are at the onset of the clinical phase. However, there are differences in the clinical course between orally and intracerebrally infected animals that may influence the detection of biomarkers.

Conclusions:

Simian vCJD can be easily triggered in cynomolgus monkeys on the oral route using less than 5 g BSE brain homogenate. The difference in the incubation period between 5 g oral and 5 mg i.c. is only 1 year (5 years versus 4 years). However, there are rapid progressors among orally dosed monkeys that develop simian v CJD as fast as intracerebrally inoculated animals.

The work referenced was performed in partial fulfillment of the study “BSE in primates“ supported by the EU (QLK1-2002-01096).

Simian vCJD can be easily triggered in cynomolgus monkeys on the oral route using less than 5 g BSE brain homogenate.

Risk of oral infection with bovine spongiform encephalopathy agent in primates

Corinne Ida Lasmézas, Emmanuel Comoy, Stephen Hawkins, Christian Herzog, Franck Mouthon, Timm Konold, Frédéric Auvré, Evelyne Correia, Nathalie Lescoutra-Etchegaray, Nicole Salès, Gerald Wells, Paul Brown, Jean-Philippe Deslys Summary The uncertain extent of human exposure to bovine spongiform encephalopathy (BSE)--which can lead to variant Creutzfeldt-Jakob disease (vCJD)--is compounded by incomplete knowledge about the efficiency of oral infection and the magnitude of any bovine-to-human biological barrier to transmission. We therefore investigated oral transmission of BSE to non-human primates. We gave two macaques a 5 g oral dose of brain homogenate from a BSE-infected cow. One macaque developed vCJD-like neurological disease 60 months after exposure, whereas the other remained free of disease at 76 months. On the basis of these findings and data from other studies, we made a preliminary estimate of the food exposure risk for man, which provides additional assurance that existing public health measures can prevent transmission of BSE to man.

Published online January 27, 2005

http://www.thelancet.com/journal/journal.isa

Calves were challenged by mouth with homogenised brain from confirmed cases of BSE. Some received 300g (3 doses of 100g), some 100g, 10g or 1g. They were then left to develop BSE, but were not subjected to the normal stresses that they might have encountered in a dairy herd. Animals in all four groups developed BSE. There has been a considerable spread of incubation period in some of the groups, but it appears as if those in the 1 and 10g challenge groups most closely fit the picture of incubation periods seen in the epidemic. Experiments in progress indicate that oral infection can occur in some animals with doses as low as 0.01g and 0.001g. .........

http://www.defra.gov.uk/animalh/bse/science-research/pathog.html#dose

It is clear that the designing scientists must also have shared Mr Bradley's surprise at the results because all the dose levels right down to 1 gram triggered infection.

6. It also appears to me that Mr Bradley's answer (that it would take less than say 100 grams) was probably given with the benefit of hindsight; particularly if one considers that later in the same answer Mr Bradley expresses his surprise that it could take as little of 1 gram of brain to cause BSE by the oral route within the same species. This information did not become available until the "attack rate" experiment had been completed in 1995/96. This was a titration experiment designed to ascertain the infective dose. A range of dosages was used to ensure that the actual result was within both a lower and an upper limit within the study and the designing scientists would not have expected all the dose levels to trigger infection. The dose ranges chosen by the most informed scientists at that time ranged from 1 gram to three times one hundred grams. It is clear that the designing scientists must have also shared Mr Bradley's surprise at the results because all the dose levels right down to 1 gram triggered infection.

Confirmed Variant Creutzfeldt-Jakob Disease (variant CJD) Case in Texas
Updated: October 7, 2014

CDC and the Texas Department of State Health Services (DSHS) have completed the investigation of the recently reported fourth vCJD case in the United States. It confirmed that the case was in a US citizen born outside the Americas and indicated that the patient's exposure to the BSE/vCJD agent most likely occurred before he moved to the United States; the patient had resided in Kuwait, Russia and Lebanon. The completed investigation did not support the patient's having had extended travel to European countries, including the United Kingdom, or travel to Saudi Arabia. The specific overseas country where this patient’s infection occurred is less clear largely because the investigation did not definitely link him to a country where other known vCJD cases likely had been infected.

Irma Linda Andablo CJD Victim, she died at 38 years old on February 6, 2010 in Mesquite Texas. She left 6 Kids and a Husband.The Purpose of this web is to give information in Spanish to the Hispanic community, and to all the community who want's information about this terrible disease.- Physician Discharge Summary, Parkland Hospital, Dallas Texas Admit Date: 12/29/2009 Discharge Date: 1/20/2010 Attending Provider: Greenberg, Benjamin Morris; General Neurology Team: General Neurology Team Linda was a Hispanic female with no past medical history presents with 14 months of incresing/progressive altered mental status, generalized weakness, inability to walk, loss of appetite, inability to speak, tremor and bowel/blader incontinence.She was, in her usual state of health up until February, 2009, when her husbans notes that she began forgetting things like names and short term memories. He also noticed mild/vague personality changes such as increased aggression. In March, she was involved in a hit and run MVA,although she was not injured. The police tracked her down and ticketed her. At that time, her son deployed to Iraq with the Army and her husband assumed her mentation changes were due to stress over these two events. Also in March, she began to have weakness in her legs, making it difficult to walk. Over the next few months, her mentation and personality changes worsened, getting to a point where she could no longer recognized her children. She was eating less and less. She was losing more weight. In the last 2-3 months, she reached the point where she could not walk without an assist, then 1 month ago, she stopped talking, only making grunting/aggressive sounds when anyone came near her. She also became both bowel and bladder incontinent, having to wear diapers. Her '"tremor'" and body jerks worsened and her hands assumed a sort of permanent grip position, leading her family to put tennis balls in her hands to protect her fingers. The husband says that they have lived in Nebraska for the past 21 years. They had seen a doctor there during the summer time who prescribed her Seroquel and Lexapro, Thinking these were sx of a mood disorder. However, the medications did not help and she continued to deteriorate clinically. Up until about 6 years ago, the pt worked at Tyson foods where she worked on the assembly line, slaughtering cattle and preparing them for packaging. She was exposed to brain and spinal cord matter when she would euthanize the cattle. The husband says that he does not know any fellow workers with a similar illness. He also says that she did not have any preceeding illness or travel.

A continuación describiremos datos de su padecimiento:

Se casó a la edad de 16 años con Everardo Andablo (Lalo) ella residió en Lexington Nebraska, desde ese entonces, trabajó aproximadamente 11 años en una compañia de matanza de vacas y procesadora de carne (Tyson) ella trabajaba en el rastro o el área de matanza, para el 2008 ella trabajaba como agente de seguridad para esta misma compañia, para ese entonces ella empezó a presentar cambios en su vida, su próximo trabajo fue en Subway dentro de una tienda comercial, donde los cambios de salud empezaron a ser muy notorios pues empezó a perder mucho peso, de 237 L de su peso normal empezó perdiendo 24 L en menos de un mes, esto era sorprendente!!! fué entonces cuando dejó el trabajo en febrero del 2009, de repente empezó a olvidar datos importantes.

La siguiente información es una traducción pertenece al comunicado que el equipo de neurologia del hospital Parkland en la ciudad de Dallas Texas liberó a su salida, después de haber estado internada del 29 de diciembre del 2009 a enero 20 del 2010, en este comunicado se encuentra el historial tanto médico como de sintomas presentados en Linda:

Physician Discharge Summary : (traducido y adaptado)

"...Mujer de 38 años presento 10 meses de una estado mental progresivo y alterado, con debilidad general, temblor, inhabilidad para caminar, para hablar, con pérdida de apetito e incontinencia de esfínteres, ella empezó a mostrar debilidad en las piernas, durante los siguientes meses su estado mental se agravó al tanto que ella no conoció más a sus propios hijos"

"El 29 de Diciembre del 2009 Fué admitida en el Hospital Parkland de Dallas por demencia de acuerdo a los síntomas de presentaba, Mujer de 38 años presentó 14 meses de una estado mental progresivo y alterado, con debilidad general, temblor, inhabilidad para caminar, para hablar, con pérdida de apetito e incontinencia de esfinteres. Ella empezó a olvidar los nombres de las personas que la rodeaban, datos importantes personales, también presentó algunos cambios de personalidad como incremento de agresión.Para el mes de Marzo del 2008 ella empezó a mostrar debilidad en las piernas, durante los siguientes meses su estado mental se agravó al tanto que ella no conoció más a sus propios hijos (6 hijos), ella cada vez comia menos, cada vez perdia más peso.Para el tiempo que ella arrivo a Dallas para la navidad del 2009 ella no caminaba en lo absoluto, no hablaba solo hacia sonidos agresivos cuando alguien se acercaba a ella, el temblor en sus manos empezó a ser más fuerte, sus manos solo tenian posición de sostener algo fuerte, ella siempre portaba pelotas pequeñas para que no se lastimara con sus propias uñas"

En terminos Médicos ella prensento un desorden mental con ansiedad y pérdida del habla y contracciones en los musculos que la inmobilizaba. Esto llevo a los médicos a predecir el diagnostico de CJD esporádico o variante, después de reuniones familiares se llego al acuerdo de no proseguir con los exámenes indicados como una biopsia cerebral debido al estado de debilidad y gravedad de ella, pues peligraba su vida y por consiguiente peligraban los médicos que le aplicarian el exámen ya que es demasiado contagioso.

Ella fué dada de alta con el diagnostico de CJD Esporádico, sin medicamento y con pocas esperanzas y semanas de vida.

PLEASE REMEMBER, IN 55 YEARS AND OLDER, THE RATE OF DOCUMENTED CJD JUMPS TO ONE IN 9,000. 
Diagnosis and Reporting of Creutzfeldt-Jakob Disease 
Singeltary, Sr et al. JAMA.2001; 285: 733-734. Vol. 285 No. 6, February 14, 2001 JAMA Diagnosis and Reporting of Creutzfeldt-Jakob Disease 
To the Editor: 
In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.

Tracking spongiform encephalopathies in North America
Xavier Bosch
Published: August 2003
Summary;
“My name is Terry S Singeltary Sr, and I live in Bacliff, Texas. I lost my mom to hvCJD (Heidenhain variant CJD) and have been searching for answers ever since. What I have found is that we have not been told the truth. CWD in deer and elk is a small portion of a much bigger problem.”
49-year-old Singeltary is one of a number of people who have remained largely unsatisfied after being told that a close relative died from a rapidly progressive dementia compatible with spontaneous Creutzfeldt-Jakob disease (CJD). So he decided to gather hundreds of documents on transmissible spongiform encephalopathies (TSE) and realised that if Britons could get variant CJD from bovine spongiform encephalopathy (BSE), Americans might get a similar disorder from chronic wasting disease (CWD) the relative of mad cow disease seen among deer and elk in the USA. Although his feverish search did not lead him to the smoking gun linking CWD to a similar disease in North American people, it did uncover a largely disappointing situation.
Singeltary was greatly demoralised at the few attempts to monitor the occurrence of CJD and CWD in the USA. Only a few states have made CJD reportable. Human and animal TSEs should be reportable nationwide and internationally, he complained in a letter to the Journal of the American Medical Association (JAMA 2003; 285: 733). "I hope that the CDC does not continue to expect us to still believe that the 85% plus of all CJD cases which are sporadic are all spontaneous, without route or source."
Until recently, CWD was thought to be confined to the wild in a small region in Colorado. But since early 2002, it has been reported in other areas, including Wisconsin, South Dakota, and the Canadian province of Saskatchewan. Indeed, the occurrence of CWD in states that were not endemic previously increased concern about a widespread outbreak and possible transmission to people and cattle.
To date, experimental studies have proven that the CWD agent can be transmitted to cattle by intracerebral inoculation and that it can cross the mucous membranes of the digestive tract to initiate infection in lymphoid tissue before invasion of the central nervous system. Yet the plausibility of CWD spreading to people has remained elusive.
Part of the problem seems to stem from the US surveillance system. CJD is only reported in those areas known to be endemic foci of CWD. Moreover, US authorities have been criticised for not having performed enough prionic tests in farm deer and elk.
Although in November last year the US Food and Drug Administration issued a directive to state public-health and agriculture officials prohibiting material from CWD-positive animals from being used as an ingredient in feed for any animal species, epidemiological control and research in the USA has been quite different from the situation in the UK and Europe regarding BSE.
"Getting data on TSEs in the USA from the government is like pulling teeth", Singeltary argues. "You get it when they want you to have it, and only what they want you to have."
Norman Foster, director of the Cognitive Disorders Clinic at the University of Michigan (Ann Arbor, MI, USA), says that "current surveillance of prion disease in people in the USA is inadequate to detect whether CWD is occurring in human beings"; adding that, "the cases that we know about are reassuring, because they do not suggest the appearance of a new variant of CJD in the USA or atypical features in patients that might be exposed to CWD. However, until we establish a system that identifies and analyses a high proportion of suspected prion disease cases we will not know for sure". The USA should develop a system modelled on that established in the UK, he points out.
Ali Samii, a neurologist at Seattle VA Medical Center who recently reported the cases of three hunters "two of whom were friends" who died from pathologically confirmed CJD, says that "at present there are insufficient data to claim transmission of CWD into humans"; adding that "[only] by asking [the questions of venison consumption and deer/elk hunting] in every case can we collect suspect cases and look into the plausibility of transmission further". Samii argues that by making both doctors and hunters more aware of the possibility of prions spreading through eating venison, doctors treating hunters with dementia can consider a possible prion disease, and doctors treating CJD patients will know to ask whether they ate venison.
CDC spokesman Ermias Belay says that the CDC "will not be investigating the [Samii] cases because there is no evidence that the men ate CWD-infected meat". He notes that although "the likelihood of CWD jumping the species barrier to infect humans cannot be ruled out 100%" and that "[we] cannot be 100% sure that CWD does not exist in humans& the data seeking evidence of CWD transmission to humans have been very limited". 
26 March 2003 
Terry S. Singeltary, retired (medically) CJD WATCH 
I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?

I would kindly like to comment on the Nature Paper, the Lancet reply, and the newspaper articles.
First, I applaud Nature, the Scientist and Authors of the Nature paper, for bringing this important finding to the attention of the public domain, and the media for printing said findings.
Secondly, it seems once again, politics is getting in the way possibly of more important Transmissible Spongiform Encephalopathy TSE Prion scientific findings. findings that could have great implications for human health, and great implications for the medical surgical arena. but apparently, the government peer review process, of the peer review science, tries to intervene again to water down said disturbing findings.
where have we all heard this before? it's been well documented via the BSE Inquiry. have they not learned a lesson from the last time?
we have seen this time and time again in England (and other Country's) with the BSE mad cow TSE Prion debacle.
That 'anonymous' Lancet editorial was disgraceful. The editor, Dick Horton is not a scientist.
The pituitary cadavers were very likely elderly and among them some were on their way to CJD or Alzheimer's. Not a bit unusual. Then the recipients, who got pooled extracts injected from thousands of cadavers, were 100% certain to have been injected with both seeds. No surprise that they got both diseases going after thirty year incubations.
That the UK has a "system in place to assist science journalists" to squash embargoed science reports they find 'alarming' is pathetic.
Sounds like the journalists had it right in the first place: 'Alzheimer's may be a transmissible infection' in The Independent to 'You can catch Alzheimer's' in The Daily Mirror or 'Alzheimer's bombshell' in The Daily Express
if not for the journalist, the layperson would not know about these important findings.
where would we be today with sound science, from where we were 30 years ago, if not for the cloak of secrecy and save the industry at all cost mentality?
when you have a peer review system for science, from which a government constantly circumvents, then you have a problem with science, and humans die.
to date, as far as documented body bag count, with all TSE prion named to date, that count is still relatively low (one was too many in my case, Mom hvCJD), however that changes drastically once the TSE Prion link is made with Alzheimer's, the price of poker goes up drastically.
so, who makes that final decision, and how many more decades do we have to wait?
the iatrogenic mode of transmission of TSE prion, the many routes there from, load factor, threshold from said load factor to sub-clinical disease, to clinical disease, to death, much time is there to spread a TSE Prion to anywhere, but whom, by whom, and when, do we make that final decision to do something about it globally? how many documented body bags does it take? how many more decades do we wait? how many names can we make up for one disease, TSE prion?
Professor Collinge et al, and others, have had troubles in the past with the Government meddling in scientific findings, that might in some way involve industry, never mind human and or animal health.
FOR any government to continue to circumvent science for monetary gain, fear factor, or any reason, shame, shame on you.
in my opinion, it's one of the reasons we are at where we are at to date, with regards to the TSE Prion disease science i.e. money, industry, politics, then comes science, in that order.
greed, corporate, lobbyist there from, and government, must be removed from the peer review process of sound science, it's bad enough having them in the pharmaceutical aspect of healthcare policy making, in my opinion.
my mother died from confirmed hvCJD, and her brother (my uncle) Alzheimer's of some type (no autopsy?). just made a promise, never forget, and never let them forget, before I do.
I kindly wish to remind the public of the past, and a possible future we all hopes never happens again. ...

Alzheimer’s disease and Transmissible Spongiform Encephalopathy prion disease, Iatrogenic, what if ?

Background

Alzheimer’s disease and Transmissible Spongiform Encephalopathy disease have both been around a long time, and was discovered in or around the same time frame, early 1900’s. Both diseases are incurable and debilitating brain disease, that are in the end, 100% fatal, with the incubation/clinical period of the Alzheimer’s disease being longer (most of the time) than the TSE prion disease. Symptoms are very similar, and pathology is very similar.

Methods

Through years of research, as a layperson, of peer review journals, transmission studies, and observations of loved ones and friends that have died from both Alzheimer’s and the TSE prion disease i.e. Heidenhain Variant Creutzfelt Jakob Disease CJD.

Results

I propose that Alzheimer’s is a TSE disease of low dose, slow, and long incubation disease, and that Alzheimer’s is Transmissible, and is a threat to the public via the many Iatrogenic routes and sources. It was said long ago that the only thing that disputes this, is Alzheimer’s disease transmissibility, or the lack of. The likelihood of many victims of Alzheimer’s disease from the many different Iatrogenic routes and modes of transmission as with the TSE prion disease.

Conclusions

There should be a Global Congressional Science round table event set up immediately to address these concerns from the many potential routes and sources of the TSE prion disease, including Alzheimer’s disease, and a emergency global doctrine put into effect to help combat the spread of Alzheimer’s disease via the medical, surgical, dental, tissue, and blood arena’s. All human and animal TSE prion disease, including Alzheimer’s should be made reportable in every state, and Internationally, WITH NO age restrictions. Until a proven method of decontamination and autoclaving is proven, and put forth in use universally, in all hospitals and medical, surgical arena’s, or the TSE prion agent will continue to spread. IF we wait until science and corporate politicians wait until politics lets science _prove_ this once and for all, and set forth regulations there from, we will all be exposed to the TSE Prion agents, if that has not happened already.

Hello Nicole,

by all means, please do use my poster. but I thought this was already taken care of, and I could not attend for my poster presentation, therefore, it was not going to be presented. I have some health issues and could not make the trip.

please see old correspondence below...

#0670: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009

Authors: T. Singeltary; Bacliff, TX/US

Title: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009

Body: Background

An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.

Methods

12 years independent research of available data

Results

I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i..e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.

Conclusion

I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries.

I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

Abstract

Bovine spongiform encephalopathy (BSE) can be efficiently transmitted to pigs via intracerebral inoculation. A clear link has been established between the consumption of products of bovine origin contaminated with the BSE agent and the development of variant Creutzfeldt-Jakob disease in humans. Small ruminants can also naturally develop BSE, and sheep-adapted BSE (Sh-BSE) propagates more efficiently than cattle BSE in pigs and in mouse models expressing porcine prion protein. In addition, Sh-BSE shows greater efficiency of transmission to human models than original cow BSE. While infectivity and/or abnormal PrP accumulation have been reported in the central nervous system in BSE-infected pigs, the ability of the agent to replicate in peripheral tissues has not been fully investigated. We previously characterized the presence of prions in a panel of tissues collected at the clinical stage of disease from pigs experimentally infected with Sh-BSE. Western blot revealed low levels of PrPres accumulation in lymphoid tissues, nerves, and skeletal muscles from 4 of the 5 animals analysed. Using protein misfolding cyclic amplification (PMCA), which we found to be 6 log fold more sensitive than direct WB for the detection of pig BSE, we confirmed the presence of the Sh-BSE agent in lymphoid organs, nerves, ileum, and striated muscles from all 5 inoculated pigs. Surprisingly, PrPres positivity was also detected in white blood cells from one pig using this method. The presence of infectivity in lymphoid tissues, striated muscles, and peripheral nerves was confirmed by bioassay in bovine PrP transgenic mice. These results demonstrate the ability of BSE-derived agents to replicate efficiently in various peripheral tissues in pigs. Although no prion transmission has been reported in pigs following oral BSE challenge, our data support the continuation of the Feed Ban measure implemented to prevent entry of the BSE agent into the feed chain.



Singeltary's comment;

cwd and scrapie transmits to pigs orally and the USA Section 21 C.F.R. 589.2000, Animal Proteins Prohibited in Ruminant Feed ban WARNING

>>>Although no prion transmission has been reported in pigs following oral BSE challenge, our data support the continuation of the Feed Ban measure implemented to prevent entry of the BSE agent into the feed chain.<<<

I would kindly like to bring urgent awareness to PLOS and the authors of this study, and the globe, the USA Section 21 C.F.R. 589.2000, Animal Proteins Prohibited in Ruminant Feed ban has been a failed policy since inception imo (see DEFRA report below), also, cervid that are potentially at risk of Chronic Wasting Disease CWD TSE Prion, are still allowed to be used as protein feed for livestock. But foremost, CWD and Scrapie TRANSMITS TO PIGS BY ORAL ROUTE. please see many many more tonnages of 589.2000, Animal Proteins Prohibited in Ruminant Feed right up to 2017. this is an extremely dangerous situation for the globe, especially with this new outbreak of TSE Prion disease in a new livestock species, i.e. camels in Nigeria, this is an extremely dangerous situation that has global ramifications and needs to be addressed asap, or risk spreading cwd tse prion from the USA and Canada further around the globe. please see;
