Two suspected Creutzfeldt-Jakob Disease cases reported in Vietnam

Two Vietnamese men have been hospitalized with symptoms of the rare degenerative brain disorder known as Creutzfeldt – Jakob Disease (CJD); however, a definitive diagnosis could not be made, according to a Thanh Nien News report today.

Confirmation testing for CJD is not available in Vietnam, according to the report.
The two men, ages 44 and 86, from Binh Phuoc Province and Ho Chi Minh City, respectively, were treated for symptoms and released. There is no treatment for CJD.
According to the Centers for Disease Control and Prevention (CDC), Prion diseases or transmissible spongiform encephalopathies (TSEs) are a family of rare progressive neurodegenerative disorders that affect both humans and animals. They are distinguished by long incubation periods, characteristic spongiform changes associated with neuronal loss, and a failure to induce inflammatory response.
The causative agents of TSEs are believed to be prions. The term “prions” refers to abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins called prion proteins that are found most abundantly in the brain.
Classic CJD is a human prion disease. It is a neurodegenerative disorder with characteristic clinical and diagnostic features. This disease is rapidly progressive and always fatal. Infection with this disease leads to death usually within 1 year of onset of illness.

Two Vietnamese men have been hospitalized with symptoms of the rare degenerative brain disorder known as Creutzfeldt – Jakob but doctors lack equipment to settle on a decisive diagnosis.
The HCMC Medical University Hospital received the first patient on August 20 -- a 44-year-old from Binh Phuoc Province, Tuoi Tre newspaper reported.
The second was an 86-year-old Ho Chi Minh City local who was admitted to the 115 People’s Hospital on September 6.
Both were discharged after being treated for their symptoms which haven't been precisely identified.
Even if doctors could be sure they suffer from CJD, which is a rare disease affecting about one in every million worldwide, no treatment is available.
Doctor Vo Don of the 115 hospital and his colleague Tran Ngoc Tai from the other said the patients suffered rapidly progressive dementia and experienced problems moving or speaking.
The 86-year-old patient, only identified as P.V.L., could only lie still when he was admitted.
Family members said he started to forget things around two years ago and his memory grew progressively worse.
More than a month after he was admitted, his condition rapidly deteriorated. He had problems walking around and holding things in his hands.
L.B.H., the other patient, initially sought treatment at a Binh Phuoc hospital where doctors were baffled by the symptoms.
He went to two other hospitals in the city where doctors could not venture a diagnosis.
By the time he arrived at the University hospital in Ho Chi Minh City, he could hardly speak or raise his legs and arms.
Tests have been performed on the patients to rule out other treatable forms of dementia such as encephalitis or meningitis.
MRI scans showed their brains' electrical patterns have become irregular.
Doctors say the results are typical of the disease, which was once considered a human form of mad cow disease.
But the doctors say they need to conduct tests on samples of a brain protein called prion to decide for sure, and hospitals in Vietnam aren't equipped for that.
Prion proteins occur in both a normal form and an infectious form, which causes the disease.
The prions cause harm when they change into the infectious form and clump together, leading to neuron loss and other brain damage.
Tai said the disease usually occurs at people from between 55 to 60 years of age.
Victims of the disease forget what they've just said, then the way home and eventually cannot recognize their own children.
Gradually, they lapse into temper tantrums, behavioral disorders and mobility problems including seizures.
In less common cases among patients between 25 and 30, the victims suffer mobility before mental problems.
They too end up in a vegetative state, the doctor said.
Depending on nursing conditions, patients can survive for several months or several years and they usually die of complications such as ulceration and bacterial infections associated with lying still for long periods of time.
Tai said the cause of the disease is not known in around 85 percent of patients.
Another 10-15 percent inherit the disease and less than 1 percent are infected by other patients’ tissues or tainted medical equipment.
His hospital has seen four patients whom they believe suffer the disease in the past seven years..
Don meanwhile said his 115 hospital receives one to two suspected cases a year.

Greetings DSHS, Dr. Fishcer, et al,
I know that most in the USA could care less about the CJD TSE prion disease aka mad cow type disease. but there are some of us here that will never forget.
you can cover up what ever you want. we all know. I have seen it happen too many times here in Texas with BSE TSE prion, either the typical or the atypical strains, or with the feed, or, with cwd, or scrapie as that goes, but we are still here, and we will never forget...

Lab tests have confirmed a diagnosis of variant Creutzfeldt-Jakob Disease (CJD) in a patient who recently died in Texas. Variant CJD is a rare, fatal brain disorder, first described in 1996 in the United Kingdom and associated with beef consumption overseas.
This is the fourth case ever reported in the United States. In each of the three previous cases, infection likely occurred outside the United States, including the United Kingdom and Saudi Arabia. The history of this fourth patient includes extensive travel to Europe and the Middle East, and infection likely occurred outside the United States. The CDC and DSHS continue to investigate the case.
There are no Texas public health concerns or threats associated with this case.

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

*** 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.
NOW, what is the latest on human risk factors to CWD strains ???

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.

***********CJD REPORT 1994 increased risk for consumption of veal and venison and lamb***********
Consumption of venison and veal was much less widespread among both cases and controls. For both of these meats there was evidence of a trend with increasing frequency of consumption being associated with increasing risk of CJD. (not nvCJD, but sporadic CJD...tss)
These associations were largely unchanged when attention was restricted to pairs with data obtained from relatives. ...
Table 9 presents the results of an analysis of these data.
There is STRONG evidence of an association between ‘’regular’’ veal eating and risk of CJD (p = .0.01).
Individuals reported to eat veal on average at least once a year appear to be at 13 TIMES THE RISK of individuals who have never eaten veal.
There is, however, a very wide confidence interval around this estimate. There is no strong evidence that eating veal less than once per year is associated with increased risk of CJD (p = 0.51).
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).
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).
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. ...
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)

Mr R.N. Elmhirst Chairman British Deer Farmers Association Holly Lodge Spencers Lane BerksWell Coventry CV7 7BZ
Dear Mr Elmhirst,
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.

*** We hypothesize that both BSE prions and CWD prions passaged through felines will seed human recPrP more efficiently than BSE or CWD from the original hosts, evidence that the new host will dampen the species barrier between humans and BSE or CWD. The new host effect is particularly relevant as we investigate potential means of trans-species transmission of prion disease.

Oral.29: Susceptibility of Domestic Cats to CWD Infection

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.

Greetings USDA/APHIS et al,
I kindly would like to comment on Docket No. 00-108-10 Chronic Wasting Disease Herd Certification Program and Interstate Movement of Farmed or Captive Deer, Elk, and Moose; Program Standards.
I believe, and in my opinion, and this has been proven by scientific facts, that without a validated and certified test for chronic wasting disease cwd, that is 100% sensitive, and in use, any voluntary effort will be futile. the voluntary ban on mad cow feed and SRMs have failed terribly, the bse mad cow surveillance program has failed terribly, as well as the testing for bse tse prion in cattle, this too has failed terrible. all this has been proven time and time again via OIG reports and GOA reports.
I believe that until this happens, 100% cwd testing with validated test, ALL MOVEMENT OF CERVIDS BETWEEN STATES MUST BE BANNED, AND THE BORDERS CLOSED TO INTERSTATE MOVEMENT OF CERVIDS. there is simply to much at risk.
In my opinion, and the opinions of many scientists and DNR officials, that these so called game farms are the cause of the spreading of chronic wasting disease cwd through much negligence. the game farms in my opinion are not the only cause, but a big factor. I kindly wish to submit the following to show what these factors are, and why interstate movement of cervids must be banned. ...

*** We conclude that TSE infectivity is likely to survive burial for long time periods with minimal loss of infectivity and limited movement from the original burial site. However PMCA results have shown that there is the potential for rainwater to elute TSE related material from soil which could lead to the contamination of a wider area. These experiments reinforce the importance of risk assessment when disposing of TSE risk materials.
*** The results show that even highly diluted PrPSc can bind efficiently to polypropylene, stainless steel, glass, wood and stone and propagate the conversion of normal prion protein. For in vivo experiments, hamsters were ic injected with implants incubated in 1% 263K-infected brain homogenate. Hamsters, inoculated with 263K-contaminated implants of all groups, developed typical signs of prion disease, whereas control animals inoculated with non-contaminated materials did not.
Conclusions. To our knowledge, this is the first established experimental model of CWD in TgSB3985. We found evidence for co-existence or divergence of two CWD strains adapted to Tga20 mice and their replication in TgSB3985 mice. Finally, we observed phenotypic differences between cervid-derived CWD and CWD/Tg20 strains upon propagation in TgSB3985 mice. Further studies are underway to characterize these strains.

Our data establish that meadow voles are permissive to CWD via peripheral exposure route, suggesting they could serve as an environmental reservoir for CWD. Additionally, our data are consistent with the hypothesis that at least two strains of CWD circulate in naturally-infected cervid populations and provide evidence that meadow voles are a useful tool for CWD strain typing.
Conclusion. CWD prions are shed in saliva and urine of infected deer as early as 3 months post infection and throughout the subsequent >1.5 year course of infection. In current work we are examining the relationship of prionemia to excretion and the impact of excreted prion binding to surfaces and particulates in the environment.
Conclusion. CWD prions (as inferred by prion seeding activity by RT-QuIC) are shed in urine of infected deer as early as 6 months post inoculation and throughout the subsequent disease course. Further studies are in progress refining the real-time urinary prion assay sensitivity and we are examining more closely the excretion time frame, magnitude, and sample variables in relationship to inoculation route and prionemia in naturally and experimentally CWD-infected cervids.
Conclusions. Our results suggested that the odds of infection for CWD is likely controlled by areas that congregate deer thus increasing direct transmission (deer-to-deer interactions) or indirect transmission (deer-to-environment) by sharing or depositing infectious prion proteins in these preferred habitats. Epidemiology of CWD in the eastern U.S. is likely controlled by separate factors than found in the Midwestern and endemic areas for CWD and can assist in performing more efficient surveillance efforts for the region.
Conclusions. During the pre-symptomatic stage of CWD infection and throughout the course of disease deer may be shedding multiple LD50 doses per day in their saliva. CWD prion shedding through saliva and excreta may account for the unprecedented spread of this prion disease in nature.

Survival and Limited Spread of TSE Infectivity after Burial

Scrapie and chronic wasting disease probably spread via environmental routes, and there are also concerns about BSE infection remaining in the environment after carcass burial or waste 3disposal. In two demonstration experiments we are determining survival and migration of TSE infectivity when buried for up to five years, as an uncontained point source or within bovine heads. Firstly boluses of TSE infected mouse brain were buried in lysimeters containing either sandy or clay soil. Migration from the boluses is being assessed from soil cores taken over time. With the exception of a very small amount of infectivity found 25 cm from the bolus in sandy soil after 12 months, no other infectivity has been detected up to three years. Secondly, ten bovine heads were spiked with TSE infected mouse brain and buried in the two soil types. Pairs of heads have been exhumed annually and assessed for infectivity within and around them. After one year and after two years, infectivity was detected in most intracranial samples and in some of the soil samples taken from immediately surrounding the heads. The infectivity assays for the samples in and around the heads exhumed at years three and four are underway. These data show that TSE infectivity can survive burial for long periods but migrates slowly. Risk assessments should take into account the likely long survival rate when infected material has been buried.

*** Susceptibility of UK red deer (Cervus alaphus elaphus) to oral BSE transmission Project Code: M03024 ***
The project confirmed that U.K red deer are susceptible to both oral and intra-cerebral inoculation with the cattle BSE agent. Six clinically positive (from 26-42 months post inoculation) i.c inoculated and one (56 months post inoculation) orally dosed deer that tested positive for TSE by immunohistochemistry and Western blotting using several primary antibodies demonstrated widespread accumulation of disease specific prion protein in the central nervous system, peripheral nervous system and enteric nervous system but none in lymphoreticular system. All showed several brain sites positive for disease specific prion protein and presented immunohistochemistry and Western blotting phenotypes with similarities to BSE in sheep, goats and cattle but unlike those seen in chronic wasting disease (CWD) in elk or scrapie in sheep. The vacuolar pathology and distribution of disease specific prion protein in red deer resembled that of CWD in most major respects however we have shown that BSE can be clearly differentiated from CWD by existing immunohistochemical and biochemical methods that are in routine use.
The knowledge gained as a result of this work will permit rapid and accurate diagnosis should a TSE ever be detected in European red deer and will also enable effective disease control methods to be quickly put in place.

Negative controls and the remaining 5 orally dosed deer culled at 72mpi tested negative by IHC and Western blot however analysis of the PrP ORF of these deer (kindly carried out by Wilfred Goldmann of the Roslin NPD) identified a Q to E polymorphism at codon 226 that may influence the efficiency of oral transmission (not published).
In the experimental BSE challenge of red deer six out of six deer succumbed to BSE when challenged by intracerebral routes but only one of six deer challenged by the oral route succumbed to infection. Deer killed at 190 days or 365 days post oral challenge showed no evidence of abnormal PrP accumulation when tested by immunocytochemistry. The PrP gene of red deer includes a Q to E polymorphism at codon 226. The table shows the distribution of these codon 226 polymorphisms within experimental challenge groups.

Immunohistochemical and biochemical characteristics of BSE and CWD in experimentally infected European red deer (Cervus elaphus elaphus)

Background: The cause of the bovine spongiform encephalopathy (BSE) epidemic in the United Kingdom (UK) was the inclusion of contaminated meat and bone meal in the protein rations fed to cattle. Those rations were not restricted to cattle but were also fed to other livestock including farmed and free living deer. Although there are no reported cases to date of natural BSE in European deer, BSE has been shown to be naturally or experimentally transmissible to a wide range of different ungulate species. Moreover, several species of North America's cervids are highly susceptible to chronic wasting disease (CWD), a transmissible spongiform encephalopathy (TSE) that has become endemic. Should BSE infection have been introduced into the UK deer population, the CWD precedent could suggest that there is a danger for spread and maintenance of the disease in both free living and captive UK deer populations. This study compares the immunohistochemical and biochemical characteristics of BSE and CWD in experimentally-infected European red deer (Cervus elpahus elaphus).
Results: After intracerebral or alimentary challenge, BSE in red deer more closely resembled natural infection in cattle rather than experimental BSE in small ruminants, due to the lack of accumulation of abnormal PrP in lymphoid tissues. In this respect it was different from CWD, and although the neuropathological features of both diseases were similar, BSE could be clearly differentiated from CWD by immunohistochemical and Western blotting methods currently in routine use.
Conclusion: Red deer are susceptible to both BSE and CWD infection, but the resulting disease phenotypes are distinct and clearly distinguishable.
Clinical disease
All six deer challenged i.c. with BSE developed clinical disease between 794 and 1260 days post-inoculation with a mean incubation period of 1027 days. A detailed description of the clinical signs was provided in an earlier report [8]. Briefly, affected deer showed variable degrees of ataxia, anorexia, circling and apparent blindness, together with failure of seasonal change of coat, weight loss and 'panic attacks'. In addition, one of six red deer orally dosed with BSE developed clinical disease 1740 days after challenge, and this animal presented with a short clinical duration of two days; the other five deer from this group remain healthy at the time of writing (65 months after challenge). Sequential rectal biopsies taken at five different time points from orally and i.c. inoculated deer were negative for PrPd.
All four deer orally challenged with CWD started to show behavioural changes between 577 and 586 days post challenge;
these progressed to definite neurological disease between 742 and 760 days post-challenge (Table 1).
Clinical signs were similar to the BSE challenged deer and included nervousness, weight loss, excessive salivation, roughness of coat, and progressive ataxia. All these CWD inoculated deer showed PrPd accumulation in the secondary follicles of rectal biopsies taken at 7 months post infection.
European red deer are susceptible to infection with the cattle BSE agent, not only by the intra-cerebral but also by the oral route, and although the clinical signs and spong- iform change are similar to those of CWD in the same species, these two infections can be easily differentiated. The lack of lymphoid involvement, the PrPd truncation pattern both "in vivo" and "in vitro", and the predominantly intracellular accumulation of PrPd are features of deer BSE that are in contrast with those of deer CWD. However, only one of six deer developed disease after alimentary exposure to 25 g of a BSE brain pool homogenate after an incubation period of nearly 5 years; this suggests a strong species barrier but if a TSE in European red deer should ever be identified then BSE/CWD discrimination would be an urgent priority. To determine whether there are potential naturally occurring BSE-like strains and to determine the degree to which there is strain variation, it would be necessary to examine many more naturally occurring CWD cases. These results will support the ongoing European surveillance for natural TSEs in red deer and the further assessment of potential risk to human health.

DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being introduced into Great Britain? A Qualitative Risk Assessment October 2012
In the USA, under the Food and Drug Administration’s BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system. However, this recommendation is guidance and not a requirement by law.
Animals considered at high risk for CWD include:
1) animals from areas declared to be endemic for CWD and/or to be CWD eradication zones and
2) deer and elk that at some time during the 60-month period prior to slaughter were in a captive herd that contained a CWD-positive animal.
Therefore, in the USA, materials from cervids other than CWD positive animals may be used in animal feed and feed ingredients for non-ruminants.
The amount of animal PAP that is of deer and/or elk origin imported from the USA to GB can not be determined, however, as it is not specified in TRACES. It may constitute a small percentage of the 8412 kilos of non-fish origin processed animal proteins that were imported from US into GB in 2011.
*** Overall, therefore, it is considered there is a __greater than negligible risk___ that (nonruminant) animal feed and pet food containing deer and/or elk protein is imported into GB.
There is uncertainty associated with this estimate given the lack of data on the amount of deer and/or elk protein possibly being imported in these products.

Creutzfeldt-Jakob disease (CJD) biannual update (August 2014), with updated guidance on decontamination of gastrointestinal endoscopy equipment
Research and analysis
*** 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).
as I said, what if ?
*** our results raise the possibility that CJD cases classified as VV1 may include cases caused by iatrogenic transmission of sCJD-MM1 prions or food-borne infection by type 1 prions from animals, e.g., chronic wasting disease prions in cervid. In fact, two CJD-VV1 patients who hunted deer or consumed venison have been reported (40, 41). The results of the present study emphasize the need for traceback studies and careful re-examination of the biochemical properties of sCJD-VV1 prions. ***

Creutzfeldt-Jakob Disease in Northeast Texas
J.A. Rawlings,*1 K.A. Hendricks1, O.M. Nuno1, D.A. Brown1, D.A. Evans2, Texas Department of Health, 1Austin and 2Tyler, Texas Creutzfeldt-Jacob Disease (CJD), a transmissible spongiform encephalopathy, is caused by prions composed of proteinaceous material devoid of nucleic acid. CJD occurs sporadically (generally 1 case/1,000,000 population per year) in older patients (average age of 65) and is characterized by rapidly progressive dementia, accompanied by severe muscle spasms and incoordination. Death usually occurs within 3 to 12 months (average 7 months). CJD activity in Texas, which has a population of nearly 19 million, appeared to be typical. The statewide death rate for 1995 and 1996 was just under 1/1,000,000. In April of 1997, the Texas Department of Health became aware of an increased number of possible CJD cases in a 23-county area of NE Texas with a population of just over one million. After review of medical and pathology records, four patients were identified with definite classic CJD and three were identified with probable CJD. Dates of death for the eight patients were from April, 1996 through mid-July 1997. The patients were from 46 through 65 years of age; four were male and three were female. A case-control study to identify risks for CJD in NE Texas has been initiated. http://www.jifsan.umd.edu/tse/Rawlings.htm

EFSA Journal 2011 The European Response to BSE: A Success Story
*** but the possibility that a small proportion of human cases so far classified as "sporadic" CJD are of zoonotic origin could not be excluded. Moreover, transmission experiments to non-human primates suggest that some TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic wasting disease (CWD) agents) might have zoonotic potential.
***In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.

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?

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.

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
T. Singeltary
Bacliff, TX, USA
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.
12 years independent research of available data
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.
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.

I kindly disagree with your synopsis for the following reasons ;
I would kindly like to add to my initial concerns, something I brought up years ago, and I believe that still hold true today, more so even than when I first stated these concerns in 2003 ;
routine passive mortality CJD surveillance USA ?
THIS has been proven not to be very useful in the U.K.;
One reason for this was the _inaccuracy_ in coding of cases correctly certified as CJD Coding is carried out by staff who are not medically qualified and it is not surprising that coding errors occur in the processing of large numbers of certificates. In 1982, 12,000 certificates per week were processed at the office of population censuses and surveys by 15 coders and 6 checkers (Alderson et al., 1983). The occurrence of both inter- and intra-observer coding errors has been described (Curb et al., 1983) and the _inaccuracies_ of BOTH certification and coding discovered in this study _support_ the introduction of a more accurate system of death certificates and a more detailed and specific coding system...
Draft Proposal For The Monitoring of Creutzfeldt-Kakob Disease 1989 Dr. R. Will
Cases of CJD may be identified from death certificates, but this alone is unlikely to provide adequate monitoring. ERRORS are made in certification and diagnosis; in the Oxford study death certificates were obtained on a series of known confirmed cases and CJD was mentioned in only 66% of certificates. In another series of 175 certified cases, 42 patients were judged not to have suffered from CJD after examination of case notes (7)...

Posted by flounder on 01 Jan 2010 at 18:11 GMT
greetings TSE PRION WORLD,
i am reminded of a few things deep throat told me years ago;
*** The most frightening thing I have read all day is the report of Gambetti's finding of a new strain of sporadic cjd in young people.........
Dear God, what in the name of all that is holy is that!!! If the US has different strains of scrapie..... why???? than the UK... then would the same mechanisms that make different strains of scrapie here make different strains of BSE... if the patterns are different in sheep and mice for scrapie..... could not the BSE be different in the cattle, in the mink, in the humans....... I really think the slides or tissues and everything from these young people with the new strain of sporadic cjd should be put up to be analyzed by many, many experts in cjd........ bse..... scrapie
Scrape the damn slide and put it into mice..... wait..... chop up the mouse brain and and spinal cord........ put into some more mice..... dammit amplify the thing and start the damned research..... This is NOT rocket science... we need to use what we know and get off our butts and move.... the whining about how long everything takes..... well it takes a whole lot longer if you whine for a year and then start the research!!!
Not sure where I read this but it was a recent press release or something like that: I thought I would fall out of my chair when I read about how there was no worry about infectivity from a histopath slide or tissues because they are preserved in formic acid, or formalin or formaldehyde..... for God's sake........ Ask any pathologist in the UK what the brain tissues in the formalin looks like after a year....... it is a big fat sponge... the agent continues to eat the brain ...... you can't make slides anymore because the agent has never stopped........ and the old slides that are stained with Hemolysin and Eosin...... they get holier and holier and degenerate and continue... what you looked at 6 months ago is not there........ Gambetti better be photographing every damned thing he is looking at.....
***Okay, you need to know. You don't need to pass it on as nothing will come of it and there is not a damned thing anyone can do about it. Don't even hint at it as it will be denied and laughed at.......... USDA is gonna do as little as possible until there is actually a human case in the USA of the nvcjd........ if you want to move this thing along and shake the earth.... then we gotta get the victims families to make sure whoever is doing the autopsy is credible, trustworthy, and a saint with the courage of Joan of Arc........ I am not kidding!!!! so, unless we get a human death from EXACTLY the same form with EXACTLY the same histopath lesions as seen in the UK nvcjd........ forget any action........ it is ALL gonna be sporadic!!! And, if there is a case....... there is gonna be every effort to link it to international travel, international food, etc. etc. etc. etc. etc. They will go so far as to find out if a sex partner had ever traveled to the UK/europe, etc. etc. .... It is gonna be a long, lonely, dangerous twisted journey to the truth. They have all the cards, all the money, and are willing to threaten and carry out those threats.... and this may be their biggest downfall...***
Thanks as always for your help. (Recently had a very startling revelation from a rather senior person in government here.......... knocked me out of my chair........ you must keep pushing. If I was a power person.... I would be demanding that there be at least a million bovine tested as soon as possible and agressively seeking this disease. The big players are coming out of the wood work as there is money to be made!!!
In short: "FIRE AT WILL"!!! for the very dumb.... who's "will"! "Will be the burden to bare if there is any coverup!"
again it was said years ago and it should be taken seriously.... BSE will NEVER be found in the US!
As for the BSE conference call... I think you did agreat service to freedom of information and making some people feign integrity... I find it scary to see that most of the "experts" are employed by the federal government or are supported on the "teat" of federal funds. A scary picture! I hope there is a confidential panel organized by the new government to really investigate this thing.
You need to watch your back........ but keep picking at them....... like a buzzard to the bone... you just may get to the truth!!! (You probably have more support than you know. Too many people are afraid to show you or let anyone else know. I have heard a few things myself... you ask the questions that everyone else is too afraid to ask.)
Mad cow disease: Could it be here?
Man's stubborn crusade attracts experts' notice By Carol Christian | August 5, 2001
yes, cjd is popping up in more and more places it seems. I think in 55 year and older, it's now 1 in 9,000.
see ;
lifetime risk of developing sporadic CJD is about 1 in 30,000, jumps to 1 in 9,000 in 50 years of age and above
IN REALITY, sporadic CJD is 1 in 9,000 in 50 years of age and above, and that's with a inadequate or what I call passive surveillance system. see below ;
Dr. William Shulaw, a veterinarian with The Ohio State University extension service, is involved in a nationwide program to eradicate scrapie, the form of BSE found in sheep.
Shulaw said the chances of a person getting sporadic Creutzfeldt- Jakob disease is about one in a million. But that's the total population, infants, children, adults and the elderly.
Chances increase to one in 9,000 when the group is restricted to those age 50 and older.
NOW, remember, the federal government lied to us for 100 years about other long incubating disease i.e. tobacco and asbestos, just to protect the industry. ...
just saying...

Confirmed Human BSE aka mad cow Variant CJD vCJD or nvCJD Case in Texas
fact is, BSE cases in Europe of the past years have dropped dramatically due to feed ban that was enforced, and extensive BSE testing, in large numbers. just the opposite has happened in the USA. it’s all been documented. there is ample evidence that there is as much of a chance (if not more), that this victim contracted human mad cow disease from sources right here in the USA. this PR push to alienate a USA source factor for human BSE in the USA is a PR stunt by the USDA inc., and not justified now, in my opinion. compare BSE testing figures in the EU compared to the USA, compare mad cow feed ban breaches, and you will see. hell, the 2004 enhanced BSE surveillance program was flawed so bad, the top Prion God at the NIH TSE prion expert Paul Brown, says he does not trust anything from the USDA since Texas covered up a mad cow for 7 months, on a 48 hour confirmation turn around. it’s all documented below in link. USDA inc shut down the mad cow testing after so many atypical BSE cases started showing up.
yes, another foreigner comes to the USA, or another USA citizens does some traveling, and all of a sudden, it’s a foreign disease. evidently, these folks never eat anything in the USA, and contracts nvcjd. right. just like the last one in 2005. really? here are the facts of the TEXAS MAD COW, MAD COW FEED in Texas, CJD CLUSTER in Texas, CJD CASE IN 38 YEAR OLD WOMAN THAT APPARENTLY WORKED ON THE SLAUGHTER LINE FOR TYSON in Texas, AND OTHER STRANGE TSE PRION DISEASE IN VERY YOUNG VICTIMS HERE IN TEXAS with long duration of illness from onset of clinical symptoms to death, CALLED SPORADIC FFI (except it is not linked to any genetic make up of that family), another nvcjd victim back in 2005 in Texas, apparently another UK victim that had moved to Texas, and never ate anything. these are the facts as I have come to know them (official documents), since hvcjd took my mom in December of 1997. just made a promise to mom, never forget, and never let them forget, the rest of the story, the truth you don’t hear about. ...our fine federal friends and the USDA inc, has lied to all of us...
