Abstract
 
A 47-year-old woman was seen for progressive behavioural and cognitive disturbances slowly evolving over a 1-year period. Neuropsychological evaluation disclosed moderate to severe impairment of all cortical functions. Besides this no other clinical abnormality was found. MRI diffusion weighted imaging disclosed hyperintense cortical lesions in a ribbon-like fashion, with restricted diffusivity. EEG showed no periodic sharp waves and CSF examination was normal, including protein 14.3.3. She was heterozygote on codon 129. Her cognitive function continued to decline and she was readmitted for further investigation at the 24th month of disease. Again no ataxia or involuntary movements were observed. MRI disclosed widespread hyperintense lesions over the entire cortex and, for the first time, also caudato-putaminal hyperintensity in T2-weighted images. EEG again failed to show periodic activity. Stereotactic biopsy disclosed moderate spongiform changes, astrocytosis and perivacuolar staining with prion-directed antibodies. Western blot analysis revealed prion type 2 mobility pattern. We discuss the clinical significance of this case: as dementia was the sole finding, and this was slowly-evolving over a 2-year period, MRI findings were the key factor suggesting a prion disease in a woman that otherwise would probably be diagnosed with a primary degenerative dementia.

Abstract
 
We present the second variant Creutzfeldt–Jacob patient in the same district of northwest Portugal as was previously reported. A 14-year-old previously healthy girl had unexplained pain in the left leg, as well as psychiatric disturbances. This was shortly followed by progressive cognitive impairment, ataxia and generalised choreoatethosis. Neuropsychological assessment revealed severe frontal and medial temporal dysfunction, the posterior cortices being spared. An electroencephalogram was normal. CSF 14.3.3 protein was slightly positive. Magnetic resonance imaging showed the “hockey stick sign” and hyperintensities in the periaquedutal grey matter and in the right parietal cortex, the last with restriction to water molecule movement. SPECT revealed perfusion defects in the left frontotemporal and right parietal regions. PRNP gene sequencing showed no mutations, the patient being homozygous to methionine in codon 129. Five months after onset, immunocytochemical and immunoblotting analysis confirmed deposition of prion protein and a PrP4t electrophoretic pattern. The patient never travelled outside Portugal or received blood transfusions. She had surgical herniorrhaphy in 1998 (when catgut was used) and 2003. This is the second case in Portugal in a 2-year period and 20 km apart from each other, with no known common exposure apart from ingestion of cow meat. We discuss these case peculiarities and underline its epidemiological significance.
 
 
The numbers of tested and positive cattle in each category in each EU Member State are published and updated regularly. Although the number of cases in the EU was increasing in 2001 and 2002, since 2003 the number of cases in the EU altogether is decreasing (EC, 2003; 2004). A total of over 10 million cattle were tested in the EU in 2004. Of these, 686 cattle were positive. Spain and Portugal were the only countries in the EU 15 Member States with an increase of cases in 2003, and Germany in 2004.

Portugal mad cow cases edge up in first half 2002
 
Portugal (July 17, 2002) - Portugal detected 49 cases of mad cow disease in the first half of 2002, eight more than a year ago, but officials said the figures were not directly comparable.
 
An official at the Agriculture Ministry's veterinary department noted that data for the first six months of 2001 did not include 60,000 cows slaughtered under European Union orders, many of which may have had mad cow disease.
 
Of the 49 positive cases of Bovine Spongiform Encephalopathy (BSE), or "mad cow" disease, 36 were detected using early screening, which had been stepped up since last year.
 
"This shows that were are identifying positive cases earlier. The number of cases from animals with suspicous symptoms is down," the official said.
 
Portugal conducted more than 42,000 screening tests in the first six months of 2002 for BSE, up from 8,500 a year ago.
 
Scientists have linked beef from animals infected with BSE to the spread of variant Creutzfeld-Jakob disease, which has killed more than 100 people, mostly in Britain.
 
A year ago, the European Union lifted a three-year embargo on beef exports from Portugal, which had been imposed due to high levels of BSE.
 
A ban on live animals remained in place, and only de-boned beef can be exported, although Portugal never was a major beef exporter.
 
Portuguese state news agency Lusa reported that the country's only plant licenced to export beef had received no export orders since the embargo was lifted.

BOVINE SPONGIFORM ENCEPHALOPATHY IN SPAIN
 
(Disease never previously reported).
 
Emergency report
 
Translation of a fax from Dr Juan José Badiola, Faculty of Veterinary Medicine, Zaragoza (National Reference Centre for Transmissible Spongiform Encephalopathies), forwarded to the OIE Central Bureau by Dr Quintiliano Pérez Bonilla, Director General of Animal Production, Ministry of Agriculture, Fisheries and Food, Madrid:
 
Report date: 22 November 2000.
 
Nature of diagnosis: clinical and post-mortem.
 
Identification of the sample:
 
The sample, taken from a five-year-old bovine (identification number LU-21492-C) was collected under the programme for monitoring bovine spongiform encephalopathy (BSE) in the Autonomous Community of Galicia. The animal had presented neurological symptoms.
 
The sample was submitted by the Animal Health and Production Laboratory(1).
 
The sample consisted of medulla oblongata and brain stem preserved in 10% formol, which were duly sent for histopathological and immunohistochemical examination.
 
Anatomopathological report:
 
A. Histopathological findings:
 
- Obex: intense vacuolation in neuropil of the dorsal nucleus of the vagus, solitary tract and spinal tract of the trigeminal nerve. Vacuolation in the pericaryon of the neurons of the dorsal nucleus of the vagus.
 
- Bridge: intense vacuolation in the pericaryon of the neurons of the vestibular nuclei.
 
- Mesencephalon: intense generalized vacuolation in neuropil.
 
B. Immunohistochemical findings:
 
An immunohistochemical examination was made of the obex and the following was observed:
 
- Positive marker located in the neuropil: deposits of the pathological protein PrPSc, which appears to be most marked in the dorsal nucleus of the vagus, the solitary tract, the spinal tract of the trigeminal nerve and the reticular formation.
 
- Positive marker located in the pericaryon of neurons and axons located principally in the dorsal nucleus of the vagus.
 
Conclusion:
 
The histopathological and immunohistochemical findings show that this animal was suffering from bovine spongiform encephalopathy.
 
This result was confirmed by the VLA Weybridge(2) (OIE Reference Laboratory for BSE).

BOVINE SPONGIFORM ENCEPHALOPATHY IN PORTUGAL in the Azores islands
 
Text of a fax received on 23 November 2000 from Dr Rui Marques Leitão, Director General of Veterinary Services, Ministry of Agriculture, Rural Development and Fisheries, Lisbon:
 
Report date: 23 November 2000.
 
A case of bovine spongiform encephalopathy (BSE) was detected in a Holstein-Friesian cow (identification number I339582) of the island of São Miguel, Azores.
 
This cow was the subject of emergency slaughter on 2 October 2000 in the abattoir at Ponta Delgada, São Miguel, in the scope of an emergency slaughter and was sampled under the BSE monitoring programme.
 
Diagnosis:
 
The sample underwent histopathological examination and immunocytochemistry at the National Laboratory of Veterinary Research, Lisbon, with positive results on 22 November.
 
Epidemiology:
 
Epidemiological investigations indicate that the cow was born on 23 September 1995, and was imported to São Miguel on 27 October 1998 from a European country.

Report on a veterinary mission to Portugal with regard to certain protective measures against BSE, and in particular, implementation of Commission Decision 98/653/EC and Commission Decision 98/272/EC (13 to 17 March 2000)
 
III. CONCLUSIONS.
 
III.2 TSE epidemio surveillance
 
The tendency to consider suspect for BSE only when an animal shows 'typical' nervous disorders can result in an underestimation of the presence of BSE in the Regions visited. In particular in the slaughterhouses visited the staff simply excluded the possibility to take in consideration other symptoms, and this could be explained in a lack of training specifically tailored for the different tasks of the veterinary services, as already recommended in previous inspections (XXIV/1061/99 AND DG(SANCO)/1227/1999);
 
The necessity to extend the monitoring program also to the emergency slaughtered animals and to the fallen stock was accepted after the last mission (DG (SANCO)1227/1999) but it is not yet operational, mainly because the necessity to allocate financial resources.
 
The number of animals sampled in the framework of Commission Decision 98/272/EC is very low in the Regions visited and it does not comply both with criteria and the minimum number of samples decided by DGV for the specific Regions, even though the DRAs have the information to properly sample most of the sub populations of bovines.
 
There is a clear tendency to focus on the suspect only as first step of the eradication measure, and not also in the framework of the BSE surveillance. This could result in a lack of sampling of the other sub- population foreseen in Commission Decision 98/272/EC.
 
The BSE case not notified to DRA's and DGV has to be considered a lack of investigation. The absence of corrective measures against the farmer does not allow to prevent similar problems in the future...

 Portugal Discovers Mad Cow Case In Imported Danish Cow
 
COPENHAGEN (Agence France-Presse) -- Portuguese authorities have uncovered a case of so-called "mad cow" disease in a cow imported from Denmark, the Danish Veterinary and Food Administration said in a statement Wednesday.
 
Although it could not be ruled out that the cow had caught bovine spongiform encephalopathy (BSE) before it left Denmark, the case did not constitute a risk to food safety there, said the organisation.
 
The cow was born in Nordvestjylland, Denmark in March 1992 and was exported to Portugal in October 1994 from a herd of only 16, none of which was still in Denmark.
 
While Portugal has reported 13 new cases of BSE so far this year and registered 170 cases in 1999, the first case of BSE in a native Danish cattle herd was announced in late February.
 
A number of countries immediately announced bans on Danish beef and Denmark pulled beef products from its shelves.
 
The Danish government admitted March 1 it had failed to follow EU guidelines fast enough to prevent the first case.
 
Denmark had previously been criticised by the European Union for acting half-heartedly on recommendations to prevent BSE, with the government proving unwilling to test dead or sick animals, or introduce new methods in abattoirs.
 
Until this year, Denmark believed its cattle were free from BSE, the only previous case having occurred in 1992 -- an import from Scotland that aroused little domestic concern.
 
Denmark has two million head of cattle.
 
 
this is just getting ridiculous, when are country's going to start taking this BSE seriously. the longer country's keep insisting they do not have BSE, without looking, the longer this disease is going to spread, and kill not only animals, but humans as well. will they ever learn???

 FINAL REPORT OF A MISSION CARRIED OUT IN PORTUGAL FROM 16 TO 20 FEBRUARY 2004 CONCERNING PROTECTIVE MEASURES AGAINST BOVINE SPONGIFORM ENCEPHALOPATHY (BSE)
 
DG(SANCO)/7214/2004 -- MR Final
 
EXECUTIVE SUMMARY
 
This report describes the outcome of a mission carried out by the Food and Veterinary Office (FVO) in Portugal, from 16 to 20 February 2004.
 
The overall objective of the mission was to evaluate the implementation of certain protective measures against BSE and the system of identification, registration and traceability of live bovine animals. More in particular, it concerned the measures put in place, and then application, to give effect to EU rules in force for the prevention, control and eradication of certain TSEs, as laid down in the Regulation (EC) No 999/2001 of the European Parliament and of the Council, as amended, and specifically addressing:
 
- both active and passive BSE epidemio-surveillance,
 
- removal and handling of Specified Risk Material (SRM),
 
- the prohibition of feeding processed animal proteins to farmed animals, and exceptions applicable to this total feed ban.
 
In terms of scope, the mission focused on bovine identification and registration, BSE epidemio-surveillance in bovine animals, removal and disposal of SRM and the feed ban, including the control and supervisory measures in place.
 
The report overall concludes that BSE surveillance in mainland Portugal has further progressed due to improvements in the bovine identification and registration system, providing more reliable data and allowing a better assessment of the rate of testing in the different sub-populations in all regions. However, sampling of all fallen stock remained problematic in 2003, in particular in Acores. Corrective measures have already been taken, notably as regards improved supervision, resulting in noticeable progress in 2004. Systems in place for removal, processing and disposal of SRM meet EU requirements, although deficiencies were found in their supervision. As regards the feed ban, and despite improvements, some shortcomings still remain in relation with planning and implementation of official controls.
 
As a potential consequence of the incomplete sampling of falling stock in the 2nd semester of 2003, calculation of the true overall BSE incidence in Portugal would be hindered. However, from January 2004, the problem seems to be largely solved, except/or Acores. Additionally, the current control plan for the total feed ban cannot fully demonstrate the efficacy of the latter.
 
The report makes a number of recommendations addressed to the Portuguese competent authorities, aimed at rectifying the identified shortcomings and/or further enhancing the implementing and control measures in place.
 
 
- Report on the Assessment of the Geographical BSE - Risk of Portugal (July 2000)
 
snip...
 
- 44 - 5. Conclusion on the Geographical BSE-Risk (GBR) 5.1 The current GBR The current geographical BSE-risk (GBR) level is IV: BSE is confirmed in domestic cattle at a higher level. • The observed incidence of clinical cases over the last 12 months (16 June 1999-15 June 2000) was 215.8 per Million adult cattle. This figure is generated by a surveillance system that was only depending on notification of suspects until recently (end 99, early 2000) some active components, targeting fallen stock, were introduced. 5.2 The expected development of the GBR • Assuming that measures in place continue to be appropriately implemented and no new external challenge occurs, the GBR will decrease over time, even if the incidence figures will only decrease sharply once the birth cohorts before 1999 will have left the system. The degree of compliance with the measures will determine the rate of decrease of the GBR. Report on the assessment of the Geographical BSE-risk of PORTUGAL July 2000 - 45 - 5.3 Recommendations for influencing the future GBR • Ensuring optimal compliance with the introduced measures is of utmost importance for supporting the decline of the GBR. All additional measures that could enhance the stability of the system further are helpful. Strengthening the active surveillance, targeting at-risk sub-populations such as fallen stock and emergency slaughter will be most useful to better assess the current extend and to monitor the development of the epidemic. By improving the ability of the system to exclude animals being at risk to incubate BSE it will also accelerate the decline of the epidemic.

FIRST CASES OF SCRAPIE FOUND IN PORTUGAL
 
The Government of Portugal has just announced the identification of two cases of a new variant of scrapie in two sheep, of which one raised in a farm in northern Portugal, and the other imported from Spain for slaughter. Both cases had been detected three months ago by routine brain testing of slaughtered sheep and goats over 18 months of age; these tests are required by the national Plan of Surveillance and Control of the “epizootic sheep tremor” set up in coordination with the EU. According to Portuguese veterinary authorities (DGV), neither of the animals, aged 24 and 26 months, showed any clinical sign of the disease. After the quick Eliza tests carried out at the slaughter plant revealed the presence of Transmittable Spongiform Encephalopathy (TSE) samples from the animals were tested in the Portuguese National Laboratory. After confirmation, they were remitted to the Weybridge reference laboratory in the U.K. where, according to the EU legislation, all cases of new diseases must also be confirmed. The Weybridge laboratory confirmed TSE but reported that the brain lesions observed did now show the typical pattern of scrapie. The laboratory later issued a provisional diagnosis that defined these two cases as a new scrapie variant. In order to be able to give a greater assurance of the diagnosis, the Weybridge laboratory will carry out further analysis.
 
These are the first cases of scrapie detected in Portugal. As a consequence, local sanitary authorities have implemented the measures required by the TSE legislation in force: sequestration of the small farm where the Portuguese-born animal was raised and slaughter and brain sampling of all co-habitants. The results of all these tests have been negative, but the authorities continue to research all relevant epidemiological features, to trace back the Portuguese case to its origins, and to determine all relevant circumstances to understand the pathology’s occurrence. According to local veterinary sources, there are other suspect cases under investigation.
 
The announcement that these are scrapie and not BSE cases has also soothed local public opinion. The Consumers Defense Association (DECO) has already reported that it is too soon to recommend any precaution regarding consumption of sheep and goat meat. Nevertheless, it also has encouraged the authorities to clarify potential risks to consumers, emphasizing the need for the Portuguese Food Safety Agency to come into force.
 
Sheep and goat production is the least significant livestock activity in Portugal, accounting for a value of production estimated at €166 million in 2002, compared to €380 million for cattle, €380 million for poultry and more than €430 million for hog production. The 2.92 million head national sheep inventory is located on 71,000 farms, most of which concentrated in the Alentejo province.

Experimental transmission of bovine spongiform encephalopathy to sheep has prompted the implementation of a surveillance plan of scrapie in small ruminants by the European Union in all member states. Since its start over 30 000 animals have been tested, and the first seven cases of sheep with detectable PrPres deposition in the central nervous system have been identified in Portugal. Notably, the pattern of PrPres distribution in the brainstem was different from that previously described for scrapie and consistent in all seven animals. Moreover, the profile of the electrophoretic mobility of PrPres after proteinase K treatment was equivalent in all cases analysed but distinct from that observed for scrapie. Notably, four animals had genotypes rarely associated with scrapie, including one animal homozygous for A136R154R171. There were no cases found to exhibit vacuolation, a pattern of PrPres distribution or PrPres electrophoretic mobility corresponding to scrapie. These data reveal a putative atypical scrapie strain in Portugal not linked to specific Prnp genotypes.

Feline spongiform encephalopathy (FSE), affecting domestic and captive feline species, is a prion disease considered to be related to bovine spongiform encephalopathy (BSE). Here we report the first case diagnosed in Portugal, highlighting the neuroapthological findings. In 2004 a 9-year old intact female Siamese cat was referred with chronic progressive behavioural changes, polydipsia, gait abnormalities and episodes of hypersalivation. Clinical signs progressed to tetraparesis and dementia and euthanasia was performed. At necropsy, brain and spinal cord had no significative changes. Tissue samples from brain, cerebellum, brainstem and spinal cord were collected for histopathology and immunohistochemistry for detection of PrPres. Histology revealed neuropil and neuronal perikarion vacuolation in several areas of the central nervous system together with gliosis and cell rarefaction at the granular layer of the cerebellum. Immunohistochemical detection of PrPres showed a strong and widespread PrPres accumulation as granular and linear deposits as well as associated with some neurons. These findings are supportive of FSE. To the authors knowledge this is the first confirmed case of FSE reported in Portugal.

Domestic and non-domestic cats have been shown to be susceptible to one prion disease, feline spongiform encephalopathy (FSE), thought to be transmitted through consumption of bovine spongiform encephalopathy (BSE) contaminated meat. Because domestic and free ranging felids scavenge cervid carcasses, including those in CWD affected areas, we evaluated the susceptibility of domestic cats to CWD infection experimentally. Groups of n = 5 cats each were inoculated either intracerebrally (IC) or orally (PO) with CWD deer brain homogenate. Between 40–43 months following IC inoculation, two cats developed mild but progressive symptoms including weight loss, anorexia, polydipsia, patterned motor behaviors and ataxia—ultimately mandating euthanasia. Magnetic resonance imaging (MRI) on the brain of one of these animals (vs. two age-matched controls) performed just before euthanasia revealed increased ventricular system volume, more prominent sulci, and T2 hyperintensity deep in the white matter of the frontal hemisphere and in cortical grey distributed through the brain, likely representing inflammation or gliosis. PrPRES and widely distributed peri-neuronal vacuoles were demonstrated in the brains of both animals by immunodetection assays. No clinical signs of TSE have been detected in the remaining primary passage cats after 80 months pi. Feline-adapted CWD was sub-passaged into groups (n=4 or 5) of cats by IC, PO, and IP/SQ routes. Currently, at 22 months pi, all five IC inoculated cats are demonstrating abnormal behavior including increasing aggressiveness, pacing, and hyper responsiveness.
 
*** Two of these cats have developed rear limb ataxia. Although the limited data from this ongoing study must be considered preliminary, they raise the potential for cervid-to-feline transmission in nature.

Domestic and nondomestic cats have been shown to be susceptible to feline spongiform encephalopathy (FSE), almost certainly caused by consumption of bovine spongiform encephalopathy (BSE)-contaminated meat. Because domestic and free-ranging nondomestic felids scavenge cervid carcasses, including those in areas affected by chronic wasting disease (CWD), we evaluated the susceptibility of the domestic cat (Felis catus) to CWD infection experimentally. Cohorts of 5 cats each were inoculated either intracerebrally (IC) or orally (PO) with CWD-infected deer brain. At 40 and 42 mo post-inoculation, two IC-inoculated cats developed signs consistent with prion disease, including a stilted gait, weight loss, anorexia, polydipsia, patterned motor behaviors, head and tail tremors, and ataxia, and progressed to terminal disease within 5 mo. Brains from these two cats were pooled and inoculated into cohorts of cats by IC, PO, and intraperitoneal and subcutaneous (IP/SC) routes. Upon subpassage, feline-adapted CWD (FelCWD) was transmitted to all IC-inoculated cats with a decreased incubation period of 23 to 27 mo. FelCWD was detected in the brains of all the symptomatic cats by western blotting and immunohistochemistry and abnormalities were seen in magnetic resonance imaging, including multifocal T2 fluid attenuated inversion recovery (FLAIR) signal hyper-intensities, ventricular size increases, prominent sulci, and white matter tract cavitation. Currently, 3 of 4 IP/SQ and 2 of 4 PO inoculared cats have developed abnormal behavior patterns consistent with the early stage of feline CWD.
 
*** These results demonstrate that CWD can be transmitted and adapted to the domestic cat, thus raising the issue of potential cervid-to- feline transmission in nature.

Transmissible Spongiform Encephalopathy TSE Prion Disease North America 2014
 
Transmissible Spongiform Encephalopathy TSE Prion Disease have now been discovered in a wide verity of species across North America. typical C-BSE, atypical L-type BASE BSE, atypical H-type BSE, atypical H-G BSE, of the bovine, typical and atypical Scrapie strains, in sheep and goats, with atypical Nor-98 Scrapie spreading coast to coast in about 5 years. Chronic Wasting Disease CWD in cervid is slowly spreading without any stopping it in Canada and the USA and now has mutated into many different strains. Transmissible Mink Encephalopathy TME outbreaks. These Transmissible Spongiform Encephalopathy TSE Prion Disease have been silently mutating and spreading in different species in North America for decades.
 
The USDA, FDA, et al have assured us of a robust Triple BSE TSE prion Firewall, of which we now know without a doubt, that it was nothing but ink on paper. Since the 1997 mad cow feed ban in the USA, literally tons and tons of banned mad cow feed has been put out into commerce, never to return, as late as December of 2013, serious, serious breaches in the FDA mad cow feed ban have been documented. The 2004 enhanced BSE surveillance program was so flawed, that one of the top TSE prion Scientist for the CDC, Dr. Paul Brown stated ; 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.
 
see ;
 
 
The BSE surveillance and testing have also been proven to be flawed, and the GAO and OIG have both raised serious question as to just how flawed it has been (see GAO and OIG reports). North America has more documented TSE prion disease, in different documented species (excluding the Zoo BSE animals in the EU), then any other place on the Globe. This does not include the very likelihood that TSE prion disease in the domestic feline and canine have been exposed to high doses of the TSE prion disease vid pet food. To date, it’s still legal to include deer from cwd zone into pet food or deer food. Specified Risk Material i.e. SRM bans still being breach, as recently as just last month.
 
nvCJD or what they now call vCJD, another case documented in Texas last month, with very little information being released to the public on about this case? with still the same line of thought from federal officials, ‘it can’t happen here’, so another vCJD blamed on travel of a foreign animal disease from another country, while ignoring all the BSE TSE Prion risk factors we have here in the USA and Canada, and the time that this victim and others, do spend in the USA, and exposed to these risk factors, apparently do not count in any way with regard to risk factor. a flawed process of risk assessment.
 
sporadic CJD, along with new TSE prion disease in humans, of which the young are dying, of which long duration of illness from onset of symptoms to death have been documented, only to have a new name added to the pot of prion disease i.e. sporadic GSS, sporadic FFI, and or VPSPR. I only ponder how a familial type disease could be sporadic with no genetic link to any family member? when the USA is the only documented Country in the world to have documented two different cases of atypical H-type BSE, with one case being called atypical H-G BSE with the G meaning Genetic, with new science now showing that indeed atypical H-type BSE is very possible transmitted to cattle via oral transmission (Prion2014). sporadic CJD and VPSPR have been rising in Canada, USA, and the UK, with the same old excuse, better surveillance. You can only use that excuse for so many years, for so many decades, until one must conclude that CJD TSE prion cases are rising. a 48% incease in CJD in Canada is not just a blip or a reason of better surveillance, it is a mathematical rise in numbers. More and more we are seeing more humans exposed in various circumstance in the Hospital, Medical, Surgical arenas to the TSE Prion disease, and at the same time in North America, more and more humans are becoming exposed to the TSE prion disease via consumption of the TSE prion via deer and elk, cattle, sheep and goats, and for those that are exposed via or consumption, go on to further expose many others via the iatrogenic modes of transmission of the TSE prion disease i.e. friendly fire. I pondered this mode of transmission via the victims of sporadic FFI, sporadic GSS, could this be a iatrogenic event from someone sub-clinical with sFFI or sGSS ? what if?
 
Two decades have passed since Dr. Ironside first confirmed his first ten nvCJD victims in 1995. Ten years later, 2005, we had Dr. Gambetti and his first ten i.e. VPSPR in younger victims. now we know that indeed VPSPR is transmissible. yet all these TSE prion disease and victims in the USA and Canada are being pawned off as a spontaneous event, yet science has shown, the spontaneous theory has never been proven in any natural case of TSE prion disease, and scientist have warned, that they have now linked some sporadic CJD cases to atypical BSE, to atypical Scrapie, and to CWD, yet we don’t here about this in the public domain. We must make all human and animal TSE prion disease reportable in every age group, in ever state and internationally, we must have a serious re-evaluation and testing of the USA cattle herds, and we must ban interstate movement of all cervids. Any voluntary effort to do any of this will fail. Folks, we have let the industry run science far too long with regards to the TSE prion disease. While the industry and their lobbyist continues to funnel junk science to our decision policy makers, Rome burns. ...end

Source of the outbreak(s) or origin of infection •Unknown or inconclusive

 

Epidemiological comments As part of the Brazilian surveillance system for Bovine Spongiform Encephalopathy (BSE), the prion marker was identified on 14 April 2014 in a 12-year-old female bovine sent for emergency slaughter because she was found fallen at her arrival at the slaughterhouse following some problems during transport. The animal was born and raised in the same full-cycle beef farm on extensive grazing. Meat and other products from this animal did not enter the food chain and there was no risk for human population. Tracing back animal movements since 2000, it was established that some animals from the birth cohort of this animal had been moved to 10 other properties in 3 municipalities in the state of Mato Grosso. During the epidemiological investigation, 49 animals from the cohort, which did not show clinical signs of the disease, were destroyed. Samples of nervous tissue were taken from the cohort animals and tested for BSE at the National Laboratory and all were negative on 1 May 2014. All control measures according to the OIE Terrestrial Animal Health Code have already been applied in order to close the outbreak and only the results of the typing tests carried out at the Reference Laboratory at Weybridge (United Kingdom) are pending.

>>>Atypical BSE, or “mad cow” disease, is a form of the prion disease not associated with the animal’s consumption of feed.<<<

 

 

don't you just love it when the officials just make stuff up $$$

 

 

*** What irks many scientists is the USDA’s April 25 statement that the rare disease is “not generally associated with an animal consuming infected feed.”

 

 

 The USDA’s conclusion is a “gross oversimplification,” said Dr. Paul Brown, one of the world’s experts on this type of disease who retired recently from the National Institutes of Health. "(The agency) has no foundation on which to base that statement.”

 

 


 

 

The present study demonstrated successful intraspecies transmission of H-type BSE to cattle and the distribution and immunolabeling patterns of PrPSc in the brain of the H-type BSE-challenged cattle. TSE agent virulence can be minimally defined by oral transmission of different TSE agents (C-type, L-type, and H-type BSE agents) [59]. Oral transmission studies with H-type BSE infected cattle have been initiated and are underway to provide information regarding the extent of similarity in the immunohistochemical and molecular features before and after transmission.

 

 

 In addition, the present data will support risk assessments in some peripheral tissues derived from cattle affected with H-type BSE.

 

 


 

 

 

 *** This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada.

 

 

 

 *** It also suggests a similar cause or source for atypical BSE in these countries. ***

 Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle. Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres.

 

 

 Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis.

 

 

 Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.

 

 

 Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. *** This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. *** It also suggests a similar cause or source for atypical BSE in these countries. ***

 Background: Classical BSE is a world-wide prion disease in cattle, and the classical BSE strain (BSE-C) has led to over 200 cases of clinical human infection (variant CJD). Atypical BSE cases have been discovered in three continents since 2004; they include the L-type (also named BASE), the H-type, and the first reported case of naturally occurring BSE with mutated bovine PRNP (termed BSE-M). The public health risks posed by atypical BSE were largely undefined.

 

 Objectives: To investigate these atypical BSE types in terms of their transmissibility and phenotypes in humanized mice. Methods: Transgenic mice expressing human PrP were inoculated with several classical (C-type) and atypical (L-, H-, or Mtype) BSE isolates, and the transmission rate, incubation time, characteristics and distribution of PrPSc, symptoms, and histopathology were or will be examined and compared.

 

 Results: Sixty percent of BASE-inoculated humanized mice became infected with minimal spongiosis and an average incubation time of 20-22 months, whereas only one of the C-type BSE-inoculated mice developed prion disease after more than 2 years. Protease-resistant PrPSc in BASE-infected humanized Tg mouse brains was biochemically different from bovine BASE or sCJD. PrPSc was also detected in the spleen of 22% of BASE-infected humanized mice, but not in those infected with sCJD. Secondary transmission of BASE in the humanized mice led to a small reduction in incubation time.*** The atypical BSE-H strain is also transmissible with distinct phenotypes in the humanized mice, but no BSE-M transmission has been observed so far.

 

 Discussion: Our results demonstrate that BASE is more virulent than classical BSE, has a lymphotropic phenotype, and displays a modest transmission barrier in our humanized mice. BSE-H is also transmissible in our humanized Tg mice. The possibility of more than two atypical BSE strains will be discussed.

 Classical BSE is a world-wide prion disease in cattle, and the classical BSE strain (BSE-C) has led to over 200 cases of clinical human infection (variant CJD). Two atypical BSE strains, BSE-L (also named BASE) and BSE-H, have been discovered in three continents since 2004. The first case of naturally occurring BSE with mutated bovine PrP gene (termed BSE-M) was also found in 2006 in the USA. The transmissibility and phenotypes of these atypical BSE strains/isolates in humans were unknown. We have inoculated humanized transgenic mice with classical and atypical BSE strains (BSE-C, BSE-L, BSE-H) and the BSE-M isolate. We have found that the atypical BSE-L strain is much more virulent than the classical BSE-C. *** The atypical BSE-H strain is also transmissible in the humanized transgenic mice with distinct phenotype, but no transmission has been observed for the BSE-M isolate so far.

 AD.56: The emergence of novel BSE prions by serial passages of H-type BSE in bovinized mice

 H-type bovine spongiform encephalopathy (BSE) is an atypical form of BSE, and has been detected in several European countries, and North America. Transmission studies of H-type BSE led to the emergence of the classical BSE (C-BSE) phenotypes during passages in inbred wild type and bovinized PrP-overexpressing transgenic mice. In this study, we conducted serial passages of Canadian H-type BSE isolate in bovinized PrP-overexpressing transgenic mice (TgBoPrP). H-type BSE isolate was transmitted to TgBoPrP with incubation periods of 320 ± 12.2 d at primary passage. The incubation period of 2nd and 3rd passage were constant (~= 220 d), no clear differences were observed in their biological and biochemical properties. However, at the forth passage, 2 different BSE phenotypes were confirmed; one is shorter survival times (109 ± 4 d) and the other is longer survival times. TgBoPrP mice with longer incubation period showed the H-type phenotype of PrPsc profile and pathology. However, those of shorter incubation period were different phenotypes from previously existed BSE prions (C-BSE, L-type BSE, and H-type BSE).

 The emergence of novel BSE prions by serial passages of H-type BSE in bovinized mice

 


 

 

 LET'S take a closer look at this new prionpathy or prionopathy, and then let's look at the g-h-BSEalabama mad cow. This new prionopathy in humans? the genetic makeup is IDENTICAL to the g-h-BSEalabama mad cow, the only _documented_ mad cow in the world to date like this, ......wait, it get's better. this new prionpathy is killing young and old humans, with LONG DURATION from onset of symptoms to death, and the symptoms are very similar to nvCJD victims, OH, and the plaques are very similar in some cases too, bbbut, it's not related to the g-h-BSEalabama cow, WAIT NOW, it gets even better, the new human prionpathy that they claim is a genetic TSE, has no relation to any gene mutation in that family. daaa, ya think it could be related to that mad cow with the same genetic make-up ??? there were literally tons and tons of banned mad cow protein in Alabama in commerce, and none of it transmitted to cows, and the cows to humans there from ??? r i g h t $$$ ALABAMA MAD COW g-h-BSEalabama In this study, we identified a novel mutation in the bovine prion protein gene (Prnp), called E211K, of a confirmed BSE positive cow from Alabama, United States of America. This mutation is identical to the E200K pathogenic mutation found in humans with a genetic form of CJD. This finding represents the first report of a confirmed case of BSE with a potential pathogenic mutation within the bovine Prnp gene. We hypothesize that the bovine Prnp E211K mutation most likely has caused BSE in "the approximately 10-year-old cow" carrying the E221K mutation.

 BSE Case Associated with Prion Protein Gene Mutation (g-h-BSEalabama) and VPSPr PRIONPATHY (see mad cow feed in COMMERCE IN ALABAMA...TSS)

 


 

 

 her healthy calf also carried the mutation (J. A. Richt and S. M. Hall PLoS Pathog. 4, e1000156; 2008).

 

 This raises the possibility that the disease could occasionally be genetic in origin. Indeed, the report of the UK BSE Inquiry in 2000 suggested that the UK epidemic had most likely originated from such a mutation and argued against the scrapierelated assumption. Such rare potential pathogenic PRNP mutations could occur in countries at present considered to be free of BSE, such as Australia and New Zealand. So it is important to maintain strict surveillance for BSE in cattle, with rigorous enforcement of the ruminant feed ban (many countries still feed ruminant proteins to pigs). Removal of specified risk material, such as brain and spinal cord, from cattle at slaughter prevents infected material from entering the human food chain. Routine genetic screening of cattle for PRNP mutations, which is now available, could provide additional data on the risk to the public. Because the point mutation identified in the Alabama animals is identical to that responsible for the commonest type of familial (genetic) CJD in humans, it is possible that the resulting infective prion protein might cross the bovine-human species barrier more easily. Patients with vCJD continue to be identified. The fact that this is happening less often should not lead to relaxation of the controls necessary to prevent future outbreaks. Malcolm A.

UPDATE SEE R-CALF CONCERNS

 

 Brazil's Second Reported BSE Case Raises Food Safety Concerns

 

 Billings, Mont. - On Monday the World Organization for Animal Health (OIE) provided notice that Brazil confirmed its second case of bovine spongiform encephalopathy (BSE), this time in a 12-year-old Brazilian cow. While the notice states that none of the meat or other products from the infected cow entered the food chain, a recent audit report by the U.S. Department of Agriculture (USDA) reveals that Brazil has not been complying with BSE safeguard measures required by the United States.

 

 A recent audit report

 


 

 

 by the USDA Food Safety and Inspection Service (FSIS) sent to the Brazilian government on April 16, 2014, reveals that Brazil has not been consistently implementing the United States' mandatory requirement that all specified risk materials (SRMs) from cattle be excluded from the human food chain as a condition for allowing Brazil to export beef to the United States.

 

 Specifically, the audit found that beginning in early 2007, the Brazilian government relaxed its SRM removal policies by issuing a notice that removed the skull, trigeminal ganglia, vertebral column, and dorsal root ganglia in cattle 30 months of age or older from the list of SRMs that must be removed at slaughter. The tissues improperly removed from the list of SRMs by the Brazilian government are tissues known to harbor the BSE agent in infected cattle.

 

 United States food safety inspectors confirmed that Brazil was not routinely removing all high-risk tissues as required for countries that export to the United States.

 

 Despite Brazil's failure to meet U.S. food safety standards, FSIS officials nevertheless determined that Brazil "continues to meet FSIS equivalence criteria at an adequate level for this component (the SRM removal component)."

 

 R-CALF USA CEO Bill Bullard said these facts demonstrate the need to fully enforce the U.S. country-of-origin labeling (COOL) law. "Only with COOL can consumers choose to avoid purchasing their food from countries with questionable food safety systems," he said.

 

 Bullard also said these facts along with USDA's current plan to begin importing beef from Brazilian states that are not free of foot-and-mouth disease (FMD) is deeply troubling.

 

 "More and more the USDA is demonstrating its unwillingness to prioritize food safety and animal health above its politically motivated trade relations goals," he concluded.
