Technical Abstract:


Transmissible spongiform encephalopathies (TSEs) are fatal neurologic diseases that affect several mammalian species including human beings. Four animal TSE agents have been reported: scrapie of sheep and goats; chronic wasting disease (CWD) of deer, elk, and moose; transmissible mink encephalopathy (TME) and bovine spongiform encephalopathy (BSE). In comparison with contagious bacterial, viral and parasitic infectious diseases, TSEs typically do not present with high morbidity or mortality rates in livestock, wildlife or human populations. The TSEs, however, remain important because of public health and international or domestic trade issues involving movement of animals. In response to the discovery of BSE, governments around the world began investing in research to determine the origin of BSE and the host range of the recognized TSEs. The prevailing theory at the time of the BSE discovery was that it had resulted from transmission of scrapie from sheep to cattle 82. Once the original interspecies transmission event had occurred it was then amplified by the subsequent feeding of meat and bone meal (MBM), a supplement that normally contains central nervous system (CNS) tissues, which inevitably became contaminated with CNS tissues from BSE affected cattle. Such practice precipitated more BSE cases, thus resulting in greater volumes of contaminated MBM supplement assisted by growing inventories of contaminated MBM prior to its discovery. Epidemiological studies suggest that classical BSE spreads through contaminated feedstuffs, and early in the UK epizootic it was suspected that the origin of the disease was scrapie,82,83 a TSE known to exist in sheep for over 200 years. However, experimental transmission of scrapie to cattle by a natural route has failed to produce disease, and while transmission of scrapie or CWD to cattle by the intracranial route produces a disease in cattle, they fail to accurately reproduce the clinical and pathologic features of BSE in cattle.25,27 Thus the origin of classical BSE remains unclear. In humans, TSEs can be acquired through exposure to infectious material, inherited as germline polymorphisms in the prion gene (PRNP), or occur spontaneously. This appears to be true in cattle as well with the belief that atypical BSE is of either spontaneous or genetic origin, and classical BSE was the form transmitted through the feeding of contaminated MBM. The original contamination of MBM in the UK remains unknown but presumably was contaminated with some form of either a spontaneous or genetic form of BSE or another not yet evaluated TSE from another host.

Protocol for further laboratory investigations into the distribution of infectivity of Atypical BSE SCIENTIFIC REPORT OF EFSA



http://bse-atypical.blogspot.com/2014/07/protocol-for-further-laboratory.html



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. ***

FDA BSE TSE PRION NEWS FEED AND ANNUAL INSPECTION OF FEED MILLS REPORTS HAS CEASED TO EXIST

American Association of Zoo Veterinarians Infectious Disease Committee Manual 2013



BOVINE SPONGIFORM ENCEPHALOPATHY (BSE)



Little is known about atypical BSE. The origin and natural routes of transmission, if any, have yet to be determined. Almost all cases have been in older cattle (usually > 8 years of age) that have shown little resemblance to the clinic-pathological picture seen in classical disease. It has been suggested that the disease may be sporadic or be caused by a genetic mutation, but no convincing evidence has been found to support either of these ideas. The correct answer will probably only come by study of the future annual incidence curves of both types of disease. Regardless of the origin of atypical BSE, the possibility of recycling the disease in cattle and other ruminants, as well as the potential for transmission to humans, mandate a continuation of feed and specified-risk materials (SRM) bans, together with diagnostic testing programs for some time to come.



snip...



Naturally occurring cases of BSE in species other than cattle have been very limited and have been linked to exposure to contaminated feed or infected carcasses. The majority of cases originated in the UK and like BSE in cattle, have declined with the implementation of feed controls. None of the exotic animals were infected in the wild.

 Possble interpretation:



 L type seems to transmit to nonhuman primates with greater ease than classical BSE



 L type also transmitted to humanized transgenic mice with higher attack rate and shorter incubation period than classical?



 H type did not transmit to Tg Hu transgenic mice

P.4.23 Transmission of atypical BSE in humanized mouse models



Liuting Qing1, Wenquan Zou1, Cristina Casalone2, Martin Groschup3, Miroslaw Polak4, Maria Caramelli2, Pierluigi Gambetti1, Juergen Richt5, Qingzhong Kong1 1Case Western Reserve University, USA; 2Instituto Zooprofilattico Sperimentale, Italy; 3Friedrich-Loeffler-Institut, Germany; 4National Veterinary Research Institute, Poland; 5Kansas State University (Previously at USDA National Animal Disease Center), USA



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 argely 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.

14th International Congress on Infectious Diseases H-type and L-type Atypical BSE January 2010 (special pre-congress edition)

Experimental Challenge of Cattle with H-type and L-type Atypical BSE

Groschup1. 1Friedrich-Loeffler-Institut, Greifswald-Insel Riems, Germany, 2Health Canada, Bureau of Microbial Hazards, Health Products & Food Branch, Ottawa, Canada, 3Health Canada, Transmissible Spongiform Encephalopathy Secretariat, Ottawa, Canada



Background: After the detection of two novel BSE forms designated H-type and L-type atypical BSE the question of the pathogenesis and the agent distribution of these two types in cattle was fully open. From initial studies of the brain pathology, it was already known that the anatomical distribution of L-type BSE differs from that of the classical type where the obex region in the brainstem always displays the highest PrPSc concentrations. In contrast in L-type BSE cases, the thalamus and frontal cortex regions showed the highest levels of the pathological prion protein, while the obex region was only weakly involved.



Methods:We performed intracranial inoculations of cattle (five and six per group) using 10%brainstemhomogenates of the two German H- and L-type atypical BSE isolates. The animals were inoculated under narcosis and then kept in a free-ranging stable under appropriate biosafety conditions. At least one animal per group was killed and sectioned in the preclinical stage and the remaining animals were kept until they developed clinical symptoms. The animals were examined for behavioural changes every four weeks throughout the experiment following a protocol that had been established during earlier BSE pathogenesis studies with classical BSE.



Results and Discussion: All animals of both groups developed clinical symptoms and had to be euthanized within 16 months. The clinical picture differed from that of classical BSE, as the earliest signs of illness were loss of body weight and depression. However, the animals later developed hind limb ataxia and hyperesthesia predominantly and the head. Analysis of brain samples from these animals confirmed the BSE infection and the atypical Western blot profile was maintained in all animals. Samples from these animals are now being examined in order to be able to describe the pathoge esis and agent distribution for these novel BSE types.



Conclusions: A pilot study using a commercially avaialble BSE rapid test ELISA revealed an essential restriction of PrPSc to the central nervous system for both atypical BSE forms. A much more detailed analysis for PrPSc and infectivity is still ongoing.

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



T. Singeltary Bacliff, TX, USA



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



Methods: 12 years independent research of available data



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



Conclusion: I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

Comment from Terry Singeltary Sr.

Docket No. APHIS-2014-0107 Bovine Spongiform Encephalopathy; Importation of Animals and Animal Products Singeltary Submission ;

I believe that there is more risk to the world from Transmissible Spongiform Encephalopathy TSE prion aka mad cow type disease now, coming from the United States and all of North America, than there is risk coming to the USA and North America, from other Countries. I am NOT saying I dont think there is any risk for the BSE type TSE prion coming from other Countries, I am just saying that in 2015, why is the APHIS/USDA/FSIS/FDA still ignoring these present mad cow risk factors in North America like they are not here?

North America has more strains of TSE prion disease, in more species (excluding zoo animals in the early BSE days, and excluding the Feline TSE and or Canine TSE, because they dont look, and yes, there has been documented evidence and scientific studies, and DEFRA Hound study, that shows the canine spongiform encephalopathy is very possible, if it has not already happened, just not documented), then any other Country in the world. Mink TME, Deer Elk cervid CWD (multiple strains), cBSE cattle, atypical L-type BSE cattle, atypical H-type BSE cattle, atyical HG type BSE cow (the only cow documented in the world to date with this strain), typical sheep goat Scrapie (multiple strains), and the atypical Nor-98 Scrapie, which has been linked to sporadic CJD, Nor-98 atypical Scrapie has spread from coast to coast. sporadic CJD on the rise, with different strains mounting, victims becoming younger, with the latest nvCJD human mad cow case being documented in Texas again, this case, NOT LINKED TO EUROPEAN TRAVEL CDC.

typical BSE can propagate as nvCJD and or sporadic CJD (Collinge et al), and sporadic CJD has now been linked to atypical BSE, Scrapie and atypical Scrapie, and scientist are very concerned with CWD TSE prion in the Cervid populations. in my opinion, the BSE MRR policy, which overtook the BSE GBR risk assessments for each country, and then made BSE confirmed countries legal to trade mad cow disease, which was all brought forth AFTER that fateful day December 23, 2003, when the USA lost its gold card i.e. BSE FREE status, thats the day it all started. once the BSE MRR policy was shoved down every countries throat by USDA inc and the OIE, then the legal trading of Scrapie was validated to be a legal trading commodity, also shoved through by the USDA inc and the OIE, the world then lost 30 years of attempted eradication of the BSE TSE prion disease typical and atypical strains, and the BSE TSE Prion aka mad cow type disease was thus made a legal trading commodity, like it or not. its all about money now folks, trade, to hell with human health with a slow incubating disease, that is 100% fatal once clinical, and forget the fact of exposure, sub-clinical infection, and friendly fire there from i.e. iatrogenic TSE prion disease, the pass it forward mode of the TSE PRION aka mad cow type disease. its all going to be sporadic CJD or sporadic ffi, or sporadic gss, or now the infamous VPSPr. ...problem solved $$$

the USDA/APHIS/FSIS/FDA triple mad cow BSE firewall, well, that was nothing but ink on paper.

for this very reason I believe the BSE MRR policy is a total failure, and that this policy should be immediately withdrawn, and set back in place the BSE GBR Risk Assessments, with the BSE GBR risk assessments set up to monitor all TSE PRION disease in all species of animals, and that the BSE GBR risk assessments be made stronger than before.

lets start with the recent notice that beef from Ireland will be coming to America.

Ireland confirmed around 1655 cases of mad cow disease. with the highest year confirming about 333 cases in 2002, with numbers of BSE confirmed cases dropping from that point on, to a documentation of 1 confirmed case in 2013, to date. a drastic decrease in the feeding of cows to cows i.e. the ruminant mad cow feed ban, and the enforcement of that ban, has drastically reduced the number of BSE cases in Europe, minus a few BABs or BARBs. a far cry from the USDA FDA triple BSE firewall, which was nothing more than ink on paper, where in 2007, in one week recall alone, some 10 MILLION POUNDS OF BANNED POTENTIAL MAD COW FEED WENT OUT INTO COMMERCE IN THE USA. this is 10 years post feed ban. in my honest opinion, due to the blatant cover up of BSE TSE prion aka mad cow disease in the USA, we still have no clue as to the true number of cases of BSE mad cow disease in the USA or North America as a whole. ...just saying.

Number of reported cases of bovine spongiform encephalopathy (BSE) in farmed cattle worldwide* (excluding the United Kingdom)

Subject: *** Becky Lockhart 46, Utah’s first female House speaker, dies diagnosed with the extremely rare Creutzfeldt-Jakob disease aka mad cow type disease

 

what is CJD ? just ask USDA inc., and the OIE, they are still feeding the public and the media industry fed junk science that is 30 years old.

 

why doesn’t some of you try reading the facts, instead of rubber stamping everything the USDA inc says.

 

sporadic CJD has now been linked to BSE aka mad cow disease, Scrapie, and there is much concern now for CWD and risk factor for humans.

 

My sincere condolences to the family and friends of the House Speaker Becky Lockhart. I am deeply saddened hear this.

 

with that said, with great respect, I must ask each and every one of you Politicians that are so deeply saddened to hear of this needless death of the Honorable House Speaker Becky Lockhart, really, cry me a friggen river. I am seriously going to ask you all this...I have been diplomatic for about 17 years and it has got no where. people are still dying. so, are you all stupid or what??? how many more need to die ??? how much is global trade of beef and other meat products that are not tested for the TSE prion disease, how much and how many bodies is this market worth?

***Moreover, L-BSE has been transmitted more easily to transgenic mice overexpressing a human PrP [13,14] or to primates [15,16] than C-BSE.

 

***It has been suggested that some sporadic CJD subtypes in humans may result from an exposure to the L-BSE agent.

 

*** Lending support to this hypothesis, pathological and biochemical similarities have been observed between L-BSE and an sCJD subtype (MV genotype at codon 129 of PRNP) [17], and between L-BSE infected non-human primate and another sCJD subtype (MM genotype) [15].

EFSA Journal 2011 The European Response to BSE: A Success Story

 

snip...

 

EFSA and the European Centre for Disease Prevention and Control (ECDC) recently delivered a scientific opinion on any possible epidemiological or molecular association between TSEs in animals and humans (EFSA Panel on Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical BSE prions as the only TSE agents demonstrated to be zoonotic so far

 

*** 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.

Seven main threats for the future linked to prions

 

First threat

 

The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed.

 

*** Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans.

 

*** These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.

 

Second threat
