One last comment Kathy.

Can you please explain to this board what DU contamination in Afganistan or any other war zones has to do with the price of beef in North America or how we can best achieve an open market for our product between having to deal with current market conditions as well as the specter of the Cargylls and the Tysons???? Remember that not all TSE scientists believe that DU and/or metal contamination has anything to do with TSE cause and effect! Consider horizontal and vertical transmission when you begin to type your reply as well as PrPsc replication in the host cell.
 
Your ignorance of what metal contamination, including DU, has on the prion protein is disappointing.

When you get your test verified, or, when the governments of our countries agree to allow testing of all animals (with existing test kits), (including private testing), we will see what the arguments of DU contamination have to do with BSE and other TSEs and neurological disorders (including Autism). The CWD correlation to our military bases in AB, and Swann Hills is very evident.

I can't believe you are so blind to these facts. All the explosive testing of weapons on military bases contributes to contamination of our environment, as do other industries and nuclear facilities eg: Rocky Flats, Co.

Our bases are not fenced off so that wild-life cannot enter them. Suffield military base (the largest in the Western World) is not fenced to keep animals out and they even have "community pastures" which they allow guinea pig grazing, or should I say cattle grazing. Fencing these animals off the bases may help, although the dust will carry the debris past any fence.

I doubt they care much about the effects of depleted uranium on Afgans

They do care about them, at least most, I believe, do. And they do care, about their family members that have travelled to Afganistan or Iraq to serve their countries. The contamination of DU nanoparticles has no borders, Ron, and it does not discriminate. The wasting associated with Gulf War Syndrome, has similar mechanisms to the wasting of TSEs. Military ranges in our own countries are used to test and practice using various weapons which contaminate the environment: chemicals and metals. [they gased my husband's uncle at Suffield during WWII, he was a conscript and they used them as human guinea pigs.]

The future will show us the effects of the nuclear age, all this nuclear testing and "progress"... Will those of us born after 1945 live to be 105? Don't count on it.

I am a cow-calf rancher, and we background our calves, and keep yearlings. Does that mean I should only care about how the toxic metals of the industries around us, only affect me - "materially"?.... We all are suffering from low prices and low moral. That doesn't mean we have a deficiency in our ethical and moral values.

We can choose to look at our problems in a tiny self-contained box, or we can realize that we all play an important part in society... and one person can make a difference.

Introduction

The work proposed here brings together top EU geo and biochemists focusing
on determining the environmental factors that affect the development of
prion diseases such as scrapie, bovine spongiform enchpalitis (BSE), chronic
wasting disease (CWD) and Creutzfeld-Jacobs disease (CJD). First the
geographical distribution of manganese and copper in soils will be
investigated as risk factors. This will be undertaken due to the fact that
prion diseases often are found in clusters. It now has been established that
the normal metal for prion protein is copper but if that metal is replaced
with manganese, the structure of the prion protein is altered. The role of
organophosphate pesticides will also be investigated because it has been
suggested that copper is complexed with organophosphate, preventing copper
absorption.

Objectives

There is clear evidence that the occurrence of prion diseases often has a
non-random distribution, suggesting a link to some environmental factors.
The work proposed here will investigate risk factors, including the role of
trace elements and organophosphates. Analysis of regional variation in local
manganese/copper levels will be determined and compared to the incidence of
the diseases. The ability of manganese and/or organophosphates in
influencing conversion of the prion protein to an abnormal and/or infectious
protein will be determined. In combination with geographical occurrence and
geo-chemical considerations this program will identify whether these
environmental considerations should be acted upon to bring about effective
prevention or at least risk minimalisation of prion diseases in the EU and
further afield.

Description of the Work

Recently it has been suggested that disbalance in dietary trace-elements
and/or exposure to organophosphates might either cause or be a risk factor
for prion disease development. In particular, high incidence of scrapie
(e.g. in Iceland), chronic wasting disease, and in Slovakia and Italy CJD
are associated with regions where soil and foliage are reported to be low in
copper and high in manganese. This proposal will address whether exposure to
a diet that has a high manganese/copper ratio can influence prion disease
will also be addressed. In particular, we shall investigate this theory at
the level of protein, cells, animals as well as geographical and
geo-chemical associations with prion diseases. Animal models of prion
disease and sheep from farms in regions of high scrapie will be investigated
for a possible influence of level of manganese and copper on incidence or
onset of these diseases. Bio-chemical and biophysical techniques will be
used to investigate interaction of the prion protein with copper and
manganese to determine the mechanism by which Mn substitution for Cu
influences conversion to the abnormal isoform of the protein and whether
such conversion results in protein that is infectious in mouse bioassay for
infectivity. Additionally, a cell culture model will be used to generate
abnormal prion protein by exposure to manganese. Cell culture model of
infection will be used to assay whether prion disease alters manganese
metabolism and transport of manganese into cells. The level of expression of
the prion protein is in itself a risk factor for prion disease as it
shortens the incubation time for the disease. This research will result in
understanding of the role of disbalance in the trace elements Cu and Mn on
the onset and mechanisms behind the occurrence of prion diseases and will
for the first time define whether there are environmental risk factors for
prion diseases.

Milestones and Expected Results

The study proposed here will produce a geo-chemical map of Europe for
manganese and copper. These maps will be used to target field areas where
prion diseases have occurred as clusters. The bio-chemical studies will
establish whether the replacement of manganese for copper in prion protein
is a risk factor for the disease _development_. Organophosphate will also be
investigated as a risk factor. The study aims at minimising the risk of
prion diseases for humans and animals in the EU.

Subject: FATEPriDE KEY FINDINGS ORGANOPHOSPHATE NO RELATIONSHIP TO CAUSE TSE
Date: May 3, 2007 at 8:41 am PST

KEY FINDINGS

Organophosphate Studies

6. Studies using phosmet (an organophosphate pesticide) were
carried out throughout the project. No relationship between this
compound and the potential to cause a TSE were identified. In
studies with oral dosing of rats, it was shown that PrP expression
levels increased in the brain but there was no association between
this and formation of proteinase K (PK) resistant PrP.


snip...


12. A model of seed protein aggregation and fibril formation was
established using PrP charged with Mn2+. PrP-Mn2+ was found to
form small circular aggregates able to catalyse further protein
aggregation and fibrilisation of PrP. This model unlike other
published models (for example those of Baskakov et al.1) does not
require the presence of denaturants and is not an autocatalytic
process (i.e. the substrate of the reaction did not aggregate). The
results suggest that Mn2+ may play a role in the formation of prion
seeds

__although further studies showed that this material was not
infectious in mouse bioassay.__

snip...

24. The project also generated information concerning the relation of
TSEs to environmental factors:
• __Potentially no role for organophosphates in TSEs.__
• Increased Mn in the diet results in higher PrP levels in the
brain.
• No conclusion is yet possible in terms of the relationship
between environmental trace element concentrations and the
geographical occurrence of TSEs (classical scrapie or BSE).
• Some confirmation was provided that in some specific farms
occurrence of classical scrapie correlates with high Mn levels.

a) As regards the involvement of organophosphates in the origin of BSE, no
new scientific
information providing evidence or supporting the hypothesis by valid data
became
available after the adoption of the last opinion of the SSC on this issue.
Consequently
there is no reason for modifying the existing opinions.
b) Regarding the possibility of OP poisoning, the European legislation for
registration of
plant protection products and veterinary medicines – addressed in the
enquiries – provide
the basis for safe use of registered compounds and their formulations.
Regarding the
alleged intoxication cases reported and OP exposure it must be concluded
that safety
measures may not have been strictly followed.

Oral transmission of kuru, Creutzfeldt-Jakob disease, and scrapie to
nonhuman primates.

Gibbs CJ Jr, Amyx HL, Bacote A, Masters CL, Gajdusek DC.

Kuru and Creutzfeldt-Jakob disease of humans and scrapie disease of
sheep and goats were transmitted to squirrel monkeys (Saimiri
sciureus) that were exposed to the infectious agents only by their
nonforced consumption of known infectious tissues. The asymptomatic
incubation period in the one monkey exposed to the virus of kuru was
36 months; that in the two monkeys exposed to the virus of
Creutzfeldt-Jakob disease was 23 and 27 months, respectively; and
that in the two monkeys exposed to the virus of scrapie was 25 and
32 months, respectively. Careful physical examination of the buccal
cavities of all of the monkeys failed to reveal signs or oral
lesions. One additional monkey similarly exposed to kuru has
remained asymptomatic during the 39 months that it has been under
observation.

Summary The uncertain extent of human exposure to bovine spongiform
encephalopathy (BSE)--which can lead to variant Creutzfeldt-Jakob disease
(vCJD)--is compounded by incomplete knowledge about the efficiency of oral
infection and the magnitude of any bovine-to-human biological barrier to
transmission. We therefore investigated oral transmission of BSE to
non-human primates. We gave two macaques a 5 g oral dose of brain homogenate
from a BSE-infected cow. One macaque developed vCJD-like neurological
disease 60 months after exposure, whereas the other remained free of disease
at 76 months. On the basis of these findings and data from other studies, we
made a preliminary estimate of the food exposure risk for man, which
provides additional assurance that existing public health measures can
prevent transmission of BSE to man.

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

study;


UK FARMER WITH BSE


1) None of our animals that contracted BSE were treated with OP's, even
in utero.
2) My kids were treated with OP's as infants to control head lice. This
seems to be endemic as infection waves in UK primary schools (and
possibly elsewhere).
3) One might argue if the continued use of british beef in the UK was
ethical, none the less it happened. We have a duty to learn from it, not
least a duty to learn on behalf of those people who died so horribly....

The etiology of sporadic Creutzfeldt-Jakob disease (sCJD), the most frequent
human
prion disease, remains still unknown. The marked disease phenotype
heterogeneity
observed in sCJD is thought to be influenced by the type of proteinase
K-resistant
prion protein, or PrPSc (type 1 or type 2 according to the electrophoretic
mobility of
the unglycosylated backbone), and by the host polymorphic Methionine/Valine
(M/V)
codon 129 of the PRNP. By using a two-dimensional gel electrophoresis
(2D-PAGE)
and imunoblotting we previously showed that in sCJD, in addition to the
PrPSc type,
distinct PrPSc C-terminal truncated fragments (CTFs) correlated with
different sCJD
subtypes. Based on the combination of CTFs and PrPSc type, we distinguished
three
PrPSc patterns: (i) the first was observed in sCJD with PrPSc type 1 of all
genotypes,;
(ii) the second was found in M/M-2 (cortical form); (iii) the third in
amyloidogenic M/V-
2 and V/V-2 subtypes (Zanusso et al., JBC 2004) . Recently, we showed that
sCJD
subtype M/V-2 shared molecular and pathological features with an atypical
form of
BSE, named BASE, thus suggesting a potential link between the two
conditions. This
connection was further confirmed after 2D-PAGE analysis, which showed an
identical
PrPSc signature, including the biochemical pattern of CTFs. To pursue this
issue, we
obtained brain homogenates from Cynomolgus macaques intracerebrally
inoculated
with brain homogenates from BASE. Samples were separated by using a
twodimensional
electrophoresis (2D-PAGE) followed by immunoblotting. We here show
that the PrPSc pattern obtained in infected primates is identical to BASE
and sCJD
MV-2 subtype. These data strongly support the link, or at least a common
ancestry,
between a sCJD subtype and BASE.

The clinical phenotype of bovine spongiform encephalopathy has been
extensively
reported in early accounts of the disorder. Following the introduction of
statutory active
surveillance, almost all BSE cases have been diagnosed on a
pathological/molecular
basis, in a pre-symptomatic clinical stage. In recent years, the active
surveillance
system has uncovered atypical BSE cases, which are characterized by distinct
conformers of the PrPSc, named high-type (BSE-H) and low-type (BSE-L), whose
clinicopathological phenotypes remain unknown. We recently reported two
Italian
atypical cases with a PrPSc type similar to BSE-L, pathologically
characterized by PrP
amyloid plaques. Experimental transmission to TgBov mice has recently
disclosed that
BASE is caused by a distinct prion strain which is extremely virulent. A
major limitation
of transmission studies to mice is the lack of reliable information on
clinical phenotype
of BASE in its natural host. In the present study, we experimentally
infected
Fresian/Holstein and Alpine/Brown cattle with Italian BSE and BASE isolates
by i.c.
route. BASE infected cattle showed survival times significantly shorter than
BSE, a
finding more readily evident in Fresian/Holstein, and in keeping with
previous
observations in TgBov mice. Clinically, BSE-infected cattle developed a
disease
phenotype highly comparable with that described in field BSE cases and in
experimentally challenged cattle. On the contrary, BASE-inoculated cattle
developed
an amyotrophic disorder accompanied by mental dullness.
The molecular and neuropathological profiles, including PrP deposition
pattern, closely
matched those observed in the original cases. This study further confirms
that BASE
is caused by a distinct prion isolate and discloses a novel disease
phenotype in cattle,
closely resembling the phenotype previous reported in scrapie-inoculated
cattle and in
some subtypes of inherited and sporadic Creutzfeldt-Jakob disease.

Pathological Interaction Between Protein Misfolding Disorders: Prions and
Alzheimer's Disease
Morales, R; Estrada, L; Castilla, J; Soto, C
University of Texas Medical Branch, Neurology, USA
Protein Misfolding Disorders (PMD) include several diverse diseases, such
Alzheimer's,
Parkinson's, Transmissible Spongiform Encephalopathies, Diabetes Type II and
various
systemic amyloidosis. The central event in these diseases is the
accumulation of a
misfolded, ß-sheet rich aggregated form of a naturally expressed protein. In
vitro
studies have shown that protein misfolding and aggregation follows a
seedingnucleation
mechanism similar to the process of crystallization. In this model, the
limiting step is the formation of small oligomeric intermediates that act as
seeds to
catalyze the polymerization process. The seeding-nucleation model provides a
rationale and plausible explanation for the infectious nature of prions.
Infectivity lies on
the capacity of preformed stable misfolded oligomeric proteins to act as a
seed to
catalyze the misfolding and aggregation process. The mechanism of misfolding
and
aggregation is similar in all PMD suggesting that misfolded aggregates have
an
inherent capability to be transmissible. Moreover, it has been shown that
oligomeric
seeds formed by one protein can accelerate the misfolding and aggregation of
another
protein, by a process termed cross-seeding. Our current study aims to assess
the
potential molecular cross-talk among PMD in vivo. For this purpose we
inoculated with
prions a transgenic mice model of Alzheimer's disease (tg2576) that develops
typical
amyloid plaques over time. 45, 303 and 365 days old transgenic and wild type
mice
were inoculated intraperitoneally with RML prions. We found significant
diminution in
prion incubation periods for tg2576 mice compared to age matched wild type
controls.
Moreover, a time dependent effect was observed, where the shorter incubation
period
was observed in animals containing larger number of amyloid plaques.
Inoculation of
tg2576-RML prions into wild type mice showed incubation periods similar to
the
original infectious material, suggesting that strains characteristics are
maintained. In
vitro data showed cross-seeding aggregation between PrPSc and Aß. Our
findings
suggest an interaction between Alzheimer's and prion pathologies, indicating
that one
protein misfolding process may be an important risk factor for the
development of a
second perhaps more prevalent disease.

Transmission Results in Squirrel Monkeys Inoculated with Human sCJD, vCJD,
and GSS Blood Specimens: the Baxter Study

Hospital, UK; 5Baxter BioSience, Austria


Background: Rodent and sheep models of Transmissible Spongiform
Encephalopathy
(TSE) have documented blood infectivity in both the pre-clinical and
clinical phases of
disease. Results in a (presumably more appropriate) non-human primate model
have not been reported.
Objective: To determine if blood components (red cells, white cells,
platelets, and
plasma) from various forms of human TSE are infectious.
Methods: Blood components were inoculated intra-cerebrally (0.1 ml) and
intravenously (0.5 ml) into squirrel monkeys from 2 patients with sporadic
Creutzfeldt- Jakob disease (sCJD) and 3 patients with variant
Creutzfeldt-Jakob disease
(vCJD). Additional monkeys were inoculated with buffy coat or plasma samples
from
chimpanzees infected with either sCJD or Gerstmann-Sträussler-Scheinker
disease (GSS). Animals were monitored for a period of 5 years, and all dying
or sacrificed animals had post-mortem neuropathological examinations and
Western blots to determine the presence or absence of the misfolded 'prion'
protein (PrPTSE).
Results: No transmissions occurred in any of the animals inoculated with
blood components from patients with sporadic or variant CJD. All donor
chimpanzees
(sCJD and GSS) became symptomatic within 6 weeks of their pre-clinical phase
plasmapheresis, several months earlier than the expected onset of illness.
One monkey inoculated with purified leukocytes from a pre-clinical GSS
chimpanzee developed disease after 36 months.
Conclusion: No infectivity was found in small volumes of blood components
from 4 patients with sporadic CJD and 3 patients with variant CJD.


***However, a single transmission from a chimpanzee-passaged strain of GSS
shows that infectivity may be present in leukocytes, and the 'shock' of
general anaesthesia and plasmspheresis appears to have triggered the onset
of illness in
pre-clinical donor chimpanzees.

Surveillance Unit, UK


BSE and vCJD transmitted to cynomolgus macaques reproduce many features of
human vCJD, including clinical symptoms, neuropathological hallmarks of
vCJD,
PrPres electrophoretical pattern and, most importantly, the wide
distribution of
infectivity in peripheral organs. The latter characteristic distinguishes
vCJD from sCJD
in both humans and cynomolgus macaques, and prompted us to use this
non-human
primate model for further investigations of vCJD and its risk for human
health. The
occurrence of four vCJD infections in humans transfused with blood from
patients who
later developed vCJD has raised concern about blood transfusion safety in
countries
with vCJD.
In this collaborative European study, we investigated the infectivity of
blood components and whole blood administered by intracerebral (ic) and
intravenous (iv) routes. Buffy-coat and whole blood was inoculated by ic and
iv route, respectively, from two vCJD patients and from two clinical
vCJD-inoculated
macaques. Transfusions were also performed from whole blood and blood
leucodepleted
according to hospital practice standards from two clinical BSE inoculated
macaques. Blood infectivity during the preclinical phase is being examined
in orally
infected macaques. Whole blood was collected and transfused from one such
animal two
years after oral challenge, whereas buffy-coat and plasma from two animals
at 2 and 4.5 years post-challenge, respectively, have been inoculated by the
ic
route.
This is an ongoing study in which recipient animals continue to be observed
at various times post-inoculation. So far, we have had one positive
transmission in one
animal transfused 65 months earlier with 40 ml of whole blood from a vCJD
macaque
(the characteristics of the disease in this animal will be shown in a
separate poster by E.
Comoy). This positive transmission reproduces transfusion transmission of
vCJD in
humans, with an incubation of 5.5 years compatible with incubation periods
observed in humans.

Protection Agency, Centre for Emergency Preparedness and Response,, UK


Background: Ongoing concerns about the prevalence of variant Creutzfeldt
Jakob
Disease (vCJD) in the UK population has heightened concerns about the risks
of iatrogenic transmission of the disease. Although there have been no cases
to date of transmission by surgery there have been 4 cases involving blood
transfusion. This study aims to assess the potential of transmission of the
disease by
dental procedures. Whilst the risks are undoubtably low the very large
numbers of
procedures carried out annually have the potential to amplify the risks
considerably
and there is very little data in this area to form the basis for accurate
risk
assessments. Aim(s)/Objective(s): To assess the relative levels of
infectivity in oral
tissues from a murine model following exposure to BSE-301V through the small
intestine.
Methods. The study uses a BSE-301V, VM mouse model as a clinically relevant
model for
assessing iatrogenic vCJD transmission between humans. Infectious mouse
brain homogenate was prepared and inoculated into a loop of the duodenum, to
prevent direct contamination of the oral tissues. Mice were sacrificed at
3-weekly
intervals and at appearance of clinical symptoms. A range of oral tissues,
including dental pulp, gingival margin, salivary gland, saliva, lingual
tonsil and
trigeminal ganglia, together with brain and spleen tissues were removed,
processed as
homogenates and reinoculated intracranially (ic.) into indicator mice.
Results: The primary challenge proved to be a very efficient route of
infection with a 100% attack rate and a mean incubation to clinical disease
of 157 ± 17 days (compared to 120 days for the same titre inoculum ic.).
Infectivity was
observed in all oral and control tissues with varying time-courses and
titres estimated from
incubation period.
Discussion: The results throw new light on the potential routes of
dissemination and spread of infectivity from the small intestine to the oral
cavity and its
implications for possible iatrogenic transmission of vCJD via dental,
endoscopic or other
forms of surgery.
Conclusion: The data generated from the study provides support for ongoing
risk assessments to look at the potential for vCJD transmission via dental
procedures alongside other elements of studies looking at effectiveness of

Creutzfeldt-Jakob disease (CJD) cases are currently classified according to
established diagnostic criteria and by the genotype at codon 129 of the PRNP
gene and the Western blotting of the proteinase K digested abnormal prion
protein
that distinguishes a type 1 and a type 2 profile. These biochemically
distinct
PrPres types have been proposed to represent distinct prion strains.
However, since the
cooccurence of type 1 and type 2 PrPres in the same patient is common, the
rationale of
this classification and strain concept as applied to CJD are currently under
discussion.
Five different brain areas from of 40 sporadic CJD and 11 iatrogenic CJD
(both dura
matter-, and growth hormone-associated) cases, originating from UK and
France, were
systematically investigated, using Western blotting typing, and by two
others
biochemical assays that depend on the behaviour of PrPSc in variable PK
digestion
conditions. As described previously, co-occurrence of type 1 and type 2
PrPres was
found in 30% of the CJD patients examined. However, our novel PK
concentration
dependent assays identified a single uniform PrP type in cases where both
type 1 and
type 2 were present. Moreover, in sCJD four distinct biochemical PrPSc
signatures were identified by the PK concentration dependent assays and
these
correlated to the current genotype/clinico-pathological sCJD groups. In iCJD
the four similar
biochemical signatures were observed, but were not correlated to particular
PRNP 129
polymorphism or Western Blot PrPres patterns. Moreover notable differences
were
observed between PrPSc biochemical properties of French and UK GH-CJD cases,
which could reflect, as already suspected, differences in the causative
agents.
Identification, in sCJD and iCJD, of four different PrPSc phenotypes
irrespective of patients PRNP polymorphism at codon 129 and Western blot
profile provides
new insights into human prion disease aetiology and could reflects an
unsuspected
diversity of TSE agents in human disease. Further investigations are
currently
underway using animal transmission to correlate agent strain with our new
discriminant biochemical assays.

Your ignorance of what metal contamination, including DU, has on the prion protein is disappointing.

Show me where my ignorance was identified?? Since I do not consider you to be a qualified peer reviewer and certainly not trained formally in Prion Science and ALL of its perculiar aspects, I would normally take your comments with a very very small pinch of salt - if at all. But, I will simply say:

I challenged you to provide some answers and Kathy, you have, yet again, failed miserably to do so. Instead, you circumvent the answers, which obviously you cannot provide and you make yourself appear to be the end-all contributor to the question of metal contamination and how it plays a role in prion science.

You are not a scientist and yet you believe yourself to be the only crusader who is actively trying to change the world. Not so Kathy. Many of us are trying to do just that and when and if we are able to provide a contribution at the end of our trials and tribulations, maybe then we too will be accepted into the fold.

Do not attempt to suppose that I am ignorant of the effects of metals on the human or the animal hosts.

Do not also make the assumption that all that you quote on this board is hard science.

Some of the information that you post is relevent in some ways and most interesting but you dare to imply that I know nothing about prion science and the effects that metals have on prions. Kathy, you could not be more wrong. The challenges I lay down here for you to pick up on largely go unanswered. Why is that? I expect that is because you do not wish to show your own ignorance.

Look, I am not trying to turn this into a war zone between your adoptive position and all-consuming love affair with the theories which Mark Purdy said or wrote. I am only trying to make some sense out of what you are writing. Some of it is good while some of it is not. It is up to you to provide accuracy - and you fail to do so many times. I suspect it is due to your rush to post it. Take some time to dig deeper and you will find more than just snippets.

As for me, I will continue to hope that you will not continuously come across as a person who is so blindly caught up in the shadow of a man who made many theories and ideas come to life but failed to really prove any of them to his peers to a point where they have been adopted and picked up by any reputable laboratories. Perhaps if he had more time?Show me I am wrong on that Kathy and take up my questions and provide the answers. If you do not wish to try at least, your credibility, not mine, may well be called into question once and for all - not just by me.

Background: Prion diseases in humans and animals are caused by conversion of a normally folded, nonpathogenic isoform (PrPC) of the prion protein to a misfolded, pathogenic isoform (PrPSc) that is transmissible. Genetic experiments have shown that the conversion reaction involves as-yet unidentified protein cofactors. The ultimate
proof of the identity of a conversion cofactor, or protein X, is the substantial decrease in susceptibility, or even resistance, to prion infection in animals in which protein X expression has been ablated. Alternatively, transgenic overexpression of protein X should lead to an accelerated onset of prion disease. Many proteins that are upregulated in prion disease or relevant to other neurodegenerative disorders, such as
Alzheimer's disease (AD), have been proposed as possible modulators of the prion incubation time; however, the identity of protein X remains elusive.

Aim: In our search for protein X, we analyzed the effect of 21 genes in a large number of mouse models on the incubation time after infection with prions. Among these were genes associated with AD, inflammation, signaling, protein expression, cycling, and maintenance.

Methods: Mice in which the gene of interest was ablated or transgenically
overexpressed were inoculated with mouse-adapted prions and the times until onset of neurologic symptoms were measured.

Results: Most genes tested here did not significantly affect incubation times in the respective mouse model after infection with prions. However, we identified the Interleukin 1 receptor, type I (Il1r1) as a significant modifier of prion incubation time, with Il1r1 knockout mice living 13% longer than wild-type mice.

Conclusion: Although Il1r1 showed a statistically significant influence on the incubation time, incubation times in prion-inoculated Il1r1-/- mice were only minimally longer than in inoculated wild-type mice, thus making it unlikely that Il1r1 is protein X. While some of the genes tested here may have a role in the normal function of PrPC, this work clearly shows that many genes formerly implicated as potential auxiliary proteins in
prion replication have no discernable effect on prion disease. Thus, we conclude that they are unlikely to be protein X.

I was looking up some old discussions we have had on TSEs and the metal connection, of course, including the depleted uranium (weapons) issue.


So, I am back to add some information to the my part of the discussion on how DU nanoparticle contamination of the brain can be/could be a major contributing factor to brain diseases, including TSEs.

The Effect of Metal Imbalances on Scrapie Neurodegeneration.
Hortells P, Monleón E, Acín C, Vargas A, Vasseur V, Salomon A, Ryffel B, Cesbron JY, Badiola JJ, Monzón M.
Research Centre for Prion Diseases, University of Zaragoza, Spain.

Summary: Environmental exposure to metal appears to enhance susceptibility to Transmissible Spongiform Encephalopathies (TSEs); however, published data are not conclusive. The current study focuses on assessing the effects of copper depletion and/or manganese enhancement in the diet on susceptibility to Scrapie and this disease progression. The degree of spongiosis was the highest in the animals that received a copper- depleted diet. These observations suggest that this diet contributes to the Scrapie lesions and to the worsening of the condition in animals that have been inoculated with Scrapie. The highest intensities of GFAP immunostaining were also associated with the copper- depleted diet. Dietary supplementation with manganese had a negative effect on neuronal counts. In conclusion, this study demonstrates that certain environmental factors may aggravate neuropathological Scrapie lesions. This is consistent with reports from other neurodegenerative diseases where some metalloenzymes play a pivotal protector role against the oxidative stress associated with pathogenesis.

Different pattern of brain pro-/anti-oxidant activity between depleted and enriched uranium in chronically exposed rats.

Uranium is not only a heavy metal but also an alpha particle emitter. The main toxicity of uranium is expected to be due to chemiotoxicity rather than to radiotoxicity. Some studies have demonstrated that uranium induced some neurological disturbances, but without clear explanations. A possible mechanism of this neurotoxicity could be the oxidative stress induced by reactive oxygen species imbalance. The aim of the present study was to determine whether a chronic ingestion of uranium induced anti-oxidative defence mechanisms in the brain of rats. Rats received depleted (DU) or 4% enriched (EU) uranyl nitrate in the drinking water at 2mg(-1)kg(-1)day(-1) for 9 months. Cerebral cortex analyses were made by measuring mRNA and protein levels and enzymatic activities. Lipid peroxidation, an oxidative stress marker, was significantly enhanced after EU exposure, but not after DU. The gene expression or activity of the main antioxidant enzymes, i.e. superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), increased significantly after chronic exposure to DU. On the contrary, oral EU administration induced a decrease of these antioxidant enzymes. The NO-ergic pathway was almost not perturbed by DU or EU exposure. Finally, DU exposure increased significantly the transporters (Divalent-Metal-Transporter1; DMT1), the storage molecule (ferritin) and the ferroxidase enzyme (ceruloplasmin), but not EU. These results illustrate that oxidative stress plays a key role in the mechanism of uranium neurotoxicity. They showed that chronic exposure to DU, but not EU, seems to induce an increase of several antioxidant agents in order to counteract the oxidative stress. Finally, these results demonstrate the importance of the double toxicity, chemical and radiological, of uranium.

BSE: OPEN CREMATION OF CARCASSES

1. THIS NOTE IS TO INFORM THE PARLIAMENTARY SECRETARY (MR MACLEAN) OF THE NEED TO CARRY OUT AN OPEN CREMATION IN THE SOUTH WEST REGION.

Background

2. In disposing of BSE carcasses, either by incineration or burial, it has been our policy to avoid open cremations if at all possible. This is because of the adverse public reaction to THOSE WHICH TOOK PLACE IN THE SOUTH WEST in the early months of the slaughter policy.

snip...

Conclusion

4. In view of this an open cremation in the area is not UNAVOIDABLE. ...

July 2009


Greetings,


Finally, let us postulate shall we. Let us just postulate that for just this one time, that mad cow disease and all other Transmissible Spongiform Encephalopathies in all other species, that have been feeding on these species, and in the laboratory studies that proves oral transmission in many different species of these TSE, and in some the lateral and vertical transmission, let us all ignore this as well, just this one time. let's just for this one second play like the spontaneous mad cow disease is for real (which i don't believe for one second), and that mad cow disease just pops up from now and then, i believe it was guesstimated to be around to be like sporadic CJD i.e. 1-2 humans per million. but some studies suggested 3 to 8 cases of spontaneous BSE per million head of cattle, but lets just say for grins, 1-2 per million as with sporadic CJD. Therefore, if we have about 100 million cattle in the U.S., we should have 100-200 cases of BSE each year, if you consider 100 million head of cattle per year in the USA.

so, my question, WHERE ARE THESE MAD COWS AT, AND OR WHERE ARE THEY BURIED AT since that last case of mad cow disease in the USA was made public around March of 2006 ???

by what miracle and how has the USA bovine been protected from mad cow disease for so many years, decades $$$

Disposal of meat and bone meal (MBM) derived from specified risk material (SRM) and over thirty month scheme carcasses by landfill The Committee was asked to consider a quantitative risk assessment of the disposal of meat and bone meal derived from specified risk material and over thirty month scheme carcasses by landfill, prepared in response to a request from the Committee at its June 1999 meeting.

The Committee was asked whether, in the light of the results of the risk assessment, it held to its earlier published (June 1999) view that landfill was an acceptable outlet for MBM of any origin, although it retained a preference for incineration. The Committee reiterated that it had a strong preference for incineration as the favoured route for the disposal of MBM and were uneasy about the use of landfill for the disposal of this material. If there were cases where incineration was not practical the Committee felt it would be preferable for any material going to landfill to be pressure-cooked first or possibly stored above ground prior to incineration.

OPINION ON

THE USE OF BURIAL FOR DEALING WITH ANIMAL

CARCASSES AND OTHER ANIMAL MATERIALS THAT

MIGHT CONTAIN BSE/TSE

ADOPTED BY THE

SCIENTIFIC STEERING COMMITTEE

MEETING OF 16-17 JANUARY 2003

The details of the SSC's evaluation are provided in the attached report. The SSC

concludes as follows:

(1) The term "burial" includes a diversity of disposal conditions. Although burial is

widely used for disposal of waste the degradation process essential for BSE/TSE

infectivity reduction is very difficult to control. The extent to which such an

infectivity reduction can occur as a consequence of burial is poorly characterised.

It would appear to be a slow process in various circumstances.

(2) A number of concerns have been identified including potential for groundwater

contamination, dispersal/transmission by birds/animals/insects, accidental

uncovering by man.

(3) In the absence of any new data the SSC confirms its previous opinion that animal

material which could possibly be contaminated with BSE/TSEs, burial poses a

risk except under highly controlled conditions (e.g., controlled landfill).

SNIP...

4. CONCLUSION

In the absence of new evidence the opinion of the SSC "Opinion on Fallen Stock"

(SSC 25th June 1999) must be endorsed strongly that land burial of all animals and

material derived from them for which there is a possibility that they could

incorporate BSE/TSEs poses a significant risk. Only in exceptional circumstances

where there could be a considerable delay in implementing a safe means of disposal

should burial of such materials be considered. Guidelines should be made available

to aid on burial site selection.

BSE CARCASE INCINERATION : UPDATE


1. In the first 9 months of 1989, 69% of suspect carcases were incinerated and 31% were buried. ...

Neither did Mr Hogg specify the date of burials, but he did tell Dr Strang that three BSE-suspect carcasses had been buried last year.

Asked by Dr Strang to list the methods of disposal that are permitted, compared with the methods at present in operation, Mr Hogg did not provide an answer to the question.

Mr Hogg did not say that no material from BSE suspects was allowed to be buried in landfill sites. However, a British government paper submitted to the EU before last year's Florence summit said that 57 legal instruments had been passed between June 1988 and May 1996, including "a requirement that all cattle which are suspected of having BSE are slaughtered and destroyed".

Early this morning, in a further twist to the story, a MAFF spokesman said that Mr Hogg had given wrong information in his answers. "There has been a mistake and a new reply will be published tomorrow," he said.

Last month, in a written Commons reply, Ms Jackson was told by the Agriculture minister Tony Baldry: "Cattle suspected of showing clinical signs of the disease are disposed of by direct incineration in plants contracted to MAFF."

Mr Baldry said that BSE suspects were not slaughtered under the over- 30-month scheme - the precautionary measure demanded by the EU as a prerequisite for lifting the ban on beef exports.

Ms Jackson subsequently raised the question of BSE burial in a Commons debate on 17 February. She was told by Roger Freeman, the Cabinet minister in charge of the cattle cull: "There are no mass graves in our countryside and there is no fear of disease."

Rare BSE mutation raises concerns over risks to public health

SIR - Atypical forms (known as H- and L-type) of bovine spongiform encephalopathy (BSE) have recently appeared in several European countries as well as in Japan, Canada and the United States. This raises the unwelcome possibility that variant Creutzfeldt-Jakob disease (vCJD) could increase in the human population. Of the atypical BSE cases tested so far, a mutation in the prion protein gene (PRNP) has been detected in just one, a cow in Alabama with BSE; 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.

Biochemical typing of pathological prion protein in aging cattle with BSE

snip...

Greetings,

O.K., let me get this straight, we have typical, U.K. c-BSE, we have now a spontaneous atypical h-BSE and l-BSE, of which they are now just calling an 'old cow disease', which happens spontaneously without any route or source, just happens.

OH, and then we have the new/old ibncBSE, of which is just another 'old cow prion disease', another one of those spontaneous events $$$

IT SEEMS there is a pattern here to make all Transmissible Spongiform Encephalopathies a spontaneous event, even though there is no such evidence what so ever.

WITH all the sub-types of TSE showing up now in the Scrapie, BSE, CWD, (all of which has been rendered and fed back to livestock producing animals for human and animal feed), and even in humans i.e. CJD, there is no way, they know for a fact that all are of a spontaneous, sporadic event, that just happened due to a twisted up protein that folded the wrong way by itself, from no route and no source. they do NOT know if any of these atypical TSE are of a spontaneous old cows prion disease or not, but yet they preach it like it's the gospel $$$

I don't believe them today, and i will never believe that 85%+ of all human sporadic CJD, just happens without any route and source from anything. ...

kind regards, terry

How susceptible pigs are to infection with sheep prions is unknown. We show, through transmission experiments in transgenic mice expressing porcine prion protein (PrP), that the susceptibility of this mouse model to bovine spongiform encephalopathy (BSE) can be enhanced after its passage in ARQ sheep, indicating that the pathogenicity of the BSE agent is modified after passage in sheep. Transgenic mice expressing porcine PrP were, nevertheless, completely resistant to infection with a broad panel of classical scrapie isolates from different sheep PrP genotypes and with different biochemical characteristics. The atypical (Nor98 like) isolate (SC-PS152) was the only scrapie isolate capable of transmission in these mice, although with a marked transmission barrier. Unexpectedly, the atypical scrapie agent appeared to undergo a strain phenotype shift upon transmission to porcine-PrP transgenic mice and acquired new strain properties, suggesting that atypical scrapie agent may exhibit different phenotypes depending on the host cellular PrP or other genetic factors.

Discussion

In this study, transgenic mice expressing porcine PrP (8) were used to assess the transmission capacity of a wide range of TSE agents from sheep. Our results indicated that none of the classical scrapie isolates tested was transmitted to our porcine PrP mouse model after intracerebral inoculation (Table), suggesting a highly (if not completely) resistance to the classical scrapie strains tested independently of their origin and biochemical signature. The absence of successful transmission of the SC-PS48 isolates with an unglycosylated bands of 19 kDa-like BSE suggests a BSE-unrelated origin for these BSE-like scrapie strains.

The atypical isolate SC-PS152 was the only scrapie isolate able to infect the Po-PrP mouse model after intracerebral inoculation (Table), albeit with a low efficiency of infection in the first passage (attack rate 16%). These results suggest the potential ability of atypical scrapie prions to infect pigs, although with a strong transmission barrier. Given the increasing number of atypical scrapie cases found in Europe and in North America, the potential ability of atypical scrapie to adapt to the pig becoming more easily transmitted could raise concerns about the potential danger of feeding ruminant meat and bone meal to swine.

In our transmission experiments, an obviously shorter survival period (458 ± 11 dpi) and an increased attack rate (100%) were observed in PoPrP-Tg001 mice inoculated with sheep BSE (Table) compared with those inoculated with the original cattle BSE (>650 dpi, 19%). These last figures correlate well with those reported for other cattle BSE isolates (Table). Differences in survival times were maintained after subsequent passages in this mouse model (Table), suggesting that the increased infectivity of sheep BSE cannot be linked to a higher infectious titer in the initial inoculum but must be the outcome of a modification in the pathogenicity of the agent. We can also rule out that the primary amino acid sequence of the ovine PrPSC leads to more efficient conversion of porcine PrPC because scrapie isolates from sheep with the same ARQ-PrP genotype were not able to infect these mice (Table). Taken together, the increased infectivity of sheep BSE in the porcine PrP mouse model must be considered as increased pathogenicity of the agent attributable to its passage in sheep. These features support previous results indicating that the BSE agent modifies its biological properties after passage in sheep, with the result that its pathogenicity increases in transgenic mice expressing bovine PrP (24). An increased pathogenicity of ovine BSE was also reported in conventional RIII mice when compared with retrospective cattle BSE experiments (36). In other prion strains, passage through an intermediate species has also been noted to alter host susceptibility (37).

The enhanced infectivity of the BSE agent after its passage in ARQ sheep raises concern about its potential danger for other species, including humans. This question, as well as others related to the infectivity of the new porcine prion generated in this study, is currently being addressed in transmission experiments using transgenic mice expressing human PrP.

Upon passages in porcine PrP transgenic mice, the BSE agent retained most of its biochemical properties, except for its PrPres glycoprofile in which some differences were appreciable. Our comparative analysis of cattle BSE and sheep BSE upon transmission in porcine PrP transgenic mice showed that both agents exhibit similar molecular (Figure 2) and neuropathologic properties (Figure 4). These features were preserved after subsequent passages. These results suggest that, despite their modified pathogenicity, the 2 porcine prions generated share the same biochemical and neuropathologic properties, regardless of whether the BSE agent used to inoculate the mice was obtained from ARQ sheep or cows. In agreement with these results, the increased infectivity of sheep BSE previously observed upon transmission in bovine PrP transgenic mice was not reflected in its molecular or neuropathologic properties (24).

The atypical scrapie (SC-PS152) agent appeared to undergo a strain phenotype shift upon transmission to porcine PrP transgenic mice. Surprisingly, this novel strain phenotype was similar to that of sheep BSE propagated in the same mice in terms of several features: 1) survival times observed after stabilization in PoPrP-Tg001 mice (second passages) were similar (Table); 2) PrPres molecular profiles of the 2 agents in porcine PrP mice were indistinguishable (Figure 3); and 3) vacuolation profiles observed in second passages largely overlapped (Figure 4).

These findings could reflect the evolutionary potential of prion agents upon transmission to a foreign host able to promote strain shift and emergence of new properties (38,39). The converging molecular, neuropathologic, and biological properties of atypical scrapie and sheep BSE upon propagation in porcine transgenic mice could be the consequence of a restriction imposed by the porcine PrPC, which might only admit a few options as it changes its conformation to PrPSC.

Our results could also suggest a common origin for sheep BSE and atypical scrapie agents, which may exhibit different phenotypes depending on the host PrPC or other host factors.

Although this last explanation seems to be less likely, so far we cannot draw any definitive conclusion on this issue. Whichever the case, the ability of an atypical scrapie to infect other species and its potential capacity to undergo a strain phenotype shift in the new host prompts new concerns about the possible spread of this uncommon TSE in other species as a masked prion undistinguishable from other strains.

IN CONFIDENCE

TRANSMISSION TO CHIMPANZEE'S

1. Kuru and CJD have been successfully transmitted to chimpanzees but scrapie and TME have not. 2. We cannot say that scrapie will not transmit to chimpanzees. There are several scrapie strains and I am not aware that all have been tried (that would have to be from mouse passaged material). Nor has a wide enough range of filed isolates subsequently strain typed in mice be inoculated by the appropriate routes (i/c, i/p and i/v).

3. I believe the proposed experiment to determine transmissibility, if conducted, would only show the susceptibility or resistance of the chimpanzee to infection/disease by the routes used and the result could not be interpreted for the predictability of the susceptibility for man. Proposals for prolonged oral exposure of chimpanzees to milk from cattle were suggested a long while ago and rejected.

4. In view of Dr. Gibbs' probable use of chimpanzees Mr. Wells' comments (enclosed) are pertinent. I have yet to receive a direct communication from Dr Schellekers but before any collaboration or provision of material we should identify the Gibbs' proposals and objectives.

5. A positive result from a chimpanzee challenged severely would likely create alarm in some circles even if the result could not be interpreted for man. I HAVE A VIEW THAT ALL THESE AGENTS COULD BE TRANSMITTED provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to RETAIN that hypothesis.

A negative result would take a lifetime to determine but that would be a shorter period than might be available for human exposure and it would still not answer the question regarding man's susceptibility. In the meantime no doubt the negativity would be used defensively. IT WOULD HOWEVER BE COUNTERPRODUCTIVE IF THE EXPERIMENT BECAME POSITIVE. We may learn more about public reactions following next Monday's meeting.

A The Present Position with respect to Scrapie A] The Problem

Scrapie is a natural disease of sheep and goats. It is a slow and inexorably progressive degenerative disorder of the nervous system and it ia fatal. It is enzootic in the United Kingdom but not in all countries.

The field problem has been reviewed by a MAFF working group (ARC 35/77). It is difficult to assess the incidence in Britain for a variety of reasons but the disease causes serious financial loss; it is estimated that it cost Swaledale breeders alone $l.7 M during the five years 1971-1975. A further inestimable loss arises from the closure of certain export markets, in particular those of the United States, to British sheep.

It is clear that scrapie in sheep is important commercially and for that reason alone effective measures to control it should be devised as quickly as possible.

Recently the question has again been brought up as to whether scrapie is transmissible to man. This has followed reports that the disease has been transmitted to primates. One particularly lurid speculation (Gajdusek 1977) conjectures that the agents of scrapie, kuru, Creutzfeldt-Jakob disease and transmissible encephalopathy of mink are varieties of a single "virus". The U.S. Department of Agriculture concluded that it could "no longer justify or permit scrapie-blood line and scrapie-exposed sheep and goats to be processed for human or animal food at slaughter or rendering plants" (ARC 84/77)" The problem is emphasised by the finding that some strains of scrapie produce lesions identical to the once which characterise the human dementias"

Whether true or not. the hypothesis that these agents might be transmissible to man raises two considerations. First, the safety of laboratory personnel requires prompt attention. Second, action such as the "scorched meat" policy of USDA makes the solution of the acrapie problem urgent if the sheep industry is not to suffer grievously.

Oral transmission of kuru, Creutzfeldt-Jakob disease, and scrapie to nonhuman primates.

Gibbs CJ Jr, Amyx HL, Bacote A, Masters CL, Gajdusek DC.

Kuru and Creutzfeldt-Jakob disease of humans and scrapie disease of sheep and goats were transmitted to squirrel monkeys (Saimiri sciureus) that were exposed to the infectious agents only by their nonforced consumption of known infectious tissues. The asymptomatic incubation period in the one monkey exposed to the virus of kuru was 36 months; that in the two monkeys exposed to the virus of Creutzfeldt-Jakob disease was 23 and 27 months, respectively; and that in the two monkeys exposed to the virus of scrapie was 25 and 32 months, respectively. Careful physical examination of the buccal cavities of all of the monkeys failed to reveal signs or oral lesions. One additional monkey similarly exposed to kuru has remained asymptomatic during the 39 months that it has been under observation.

3.57 The experiment which might have determined whether BSE and scrapie were caused by the same agent (ie, the feeding of natural scrapie to cattle) was never undertaken in the UK. It was, however, performed in the USA in 1979, when it was shown that cattle inoculated with the scrapie agent endemic in the flock of Suffolk sheep at the United States Department of Agriculture in Mission, Texas, developed a TSE quite unlike BSE.339 The findings of the initial transmission, though not of the clinical or neurohistological examination, were communicated in October 1988 to Dr Watson, Director of the CVL, following a visit by Dr Wrathall, one of the project leaders in the Pathology Department of the CVL, to the United States Department of Agriculture.340 The results were not published at this point, since the attempted transmission to mice from the experimental cow brain had been inconclusive. The results of the clinical and histological differences between scrapie-affected sheep and cattle were published in 1995. Similar studies in which cattle were inoculated intracerebrally with scrapie inocula derived from a number of scrapie-affected sheep of different breeds and from different States, were carried out at the US National Animal Disease Centre.341 The results, published in 1994, showed that this source of scrapie agent, though pathogenic for cattle,

*** did not produce the same clinical signs of brain lesions characteristic of BSE. ***

3.58 There are several possible reasons why the experiment was not performed in the UK. It had been recommended by Sir Richard Southwood (Chairman of the Working Party on Bovine Spongiform Encephalopathy) in his letter to the Permanent Secretary of MAFF, Mr (now Sir) Derek Andrews, on 21 June 1988,342 though it was not specifically recommended in the Working Party Report or indeed in the Tyrrell Committee Report (details of the Southwood Working Party and the Tyrell Committee can be found in vol. 4: The Southwood Working Party, 1988–89 and vol. 11: Scientists after Southwood respectively). The direct inoculation of scrapie into calves was given low priority, because of its high cost and because it was known that it had already taken place in the USA.343 It was also felt that the results of such an experiment would be hard to interpret. While a negative result 337 Fraser, H., Bruce, M., Chree, A., McConnell, I. and Wells, G. (1992) Transmission of Bovine Spongiform Encephalopathy and Scrapie to Mice, Journal of General Virology, 73, 1891–7; Bruce, M., Chree, A., McConnell, I., Foster, J., Pearson, G. and Fraser, H.

Such an experiment would be expensive. Secondly, as measures to control the epidemic took hold, the need for the experiment from the policy viewpoint was not considered so urgent. It was felt that the results would be mainly of academic interest.345 3.59 Nevertheless, from the first demonstration of transmissibility of BSE in 1988, the possibility of differences in the transmission properties of BSE and scrapie was clear. Scrapie was transmissible to hamsters, but by 1988 attempts to transmit BSE to hamsters had failed. Subsequent findings increased that possibility.

3. Prof. A Robertson gave a brief account of BSE. The US approach was to accord it a very low profile indeed. Dr. A Thiermann showed the picture in the ''Independent'' with cattle being incinerated and thought this was a fanatical incident to be avoided in the US at all costs. BSE was not reported in the USA.

Greetings,

it would be interesting to know what year these atypical cases occurred, as opposed to lumping them in with the totals only.

are they accumulating ?

did they occur in one year, two years, same state, same city ?

location would be very interesting ?

age group ?

sex ?

how was it determined that nvCJD was ruled out ?

from 1997, the year i started dealing with this nightmare, there were 28 cases (per this report), up until 2007 where the total was 185 cases (per this report), and to date 2008 is at 182. a staggering increase in my opinion, for something that just happens spontaneously as some would have us believe. i don't believe it, not in 85%+ of all sporadic CJD cases. actually, i do not believe yet that anyone has proven that any of the sporadic CJD cases have been proven to be a spontaneous misfolding of a protein. there are many potential routes and sources for the sporadic CJD's. ...TSS

Abstract:

TSEs have been rampant in the USA for decades in many species, and they all have been rendered and fed back to animals for human/animal consumption. 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 2007. snip...

U.S. Scientist should be concerned with a CJD epidemic in the U.S., as well... 2 January 2000

Terry S Singeltary retired Send response to journal: Re: U.S. Scientist should be concerned with a CJD epidemic in the U.S., as well...

In reading your short article about 'Scientist warn of CJD epidemic' news in brief Jan. 1, 2000. I find the findings in the PNAS old news, made famous again. Why is the U.S. still sitting on their butts, ignoring the facts? We have the beginning of a CJD epidemic in the U.S., and the U.S. Gov. is doing everything in it's power to conceal it.

The exact same recipe for B.S.E. existed in the U.S. for years and years. In reading over the Qualitative Analysis of BSE Risk Factors-1, this is a 25 page report by the USDA:APHIS:VS. It could have been done in one page. The first page, fourth paragraph says it all;

"Similarities exist in the two countries usage of continuous rendering technology and the lack of usage of solvents, however, large differences still remain with other risk factors which greatly reduce the potential risk at the national level."

Then, the next 24 pages tries to down-play the high risks of B.S.E. in the U.S., with nothing more than the cattle to sheep ratio count, and the geographical locations of herds and flocks. That's all the evidence they can come up with, in the next 24 pages.

Something else I find odd, page 16;

"In the United Kingdom there is much concern for a specific continuous rendering technology which uses lower temperatures and accounts for 25 percent of total output. This technology was _originally_ designed and imported from the United States. However, the specific application in the production process is _believed_ to be different in the two countries."

A few more factors to consider, page 15;

"Figure 26 compares animal protein production for the two countries. The calculations are based on slaughter numbers, fallen stock estimates, and product yield coefficients. This approach is used due to variation of up to 80 percent from different reported sources. At 3.6 million tons, the United States produces 8 times more animal rendered product than the United Kingdom."

"The risk of introducing the BSE agent through sheep meat and bone meal is more acute in both relative and absolute terms in the United Kingdom (Figures 27 and 28). Note that sheep meat and bone meal accounts for 14 percent, or 61 thousand tons, in the United Kingdom versus 0.6 percent or 22 thousand tons in the United States. For sheep greater than 1 year, this is less than one-tenth of one percent of the United States supply."

"The potential risk of amplification of the BSE agent through cattle meat and bone meal is much greater in the United States where it accounts for 59 percent of total product or almost 5 times more than the total amount of rendered product in the United Kingdom."

Considering, it would only take _one_ scrapie infected sheep to contaminate the feed. Considering Scrapie has run rampant in the U.S. for years, as of Aug. 1999, 950 scrapie infected flocks. Also, Considering only one quarter spoonful of scrapie infected material is lethal to a cow. Considering all this, the sheep to cow ration is meaningless. As I said, it's 24 pages of B.S.e.

To be continued...

Re: vCJD in the USA * BSE in U.S. Terry S Singeltary (15 November 1999)

In reading the recent article in the BMJ about the potential BSE tests being developed in the U.S. and Bart Van Everbroeck reply. It does not surprize me, that the U.S. has been concealing vCJD. There have been people dying from CJD, with all the symptoms and pathological findings that resemble U.K. vCJD for some time. It just seems that when there is one found, they seem to change the clarical classification of the disease, to fit their agenda. I have several autopsies, stating kuru type amyloid plaques, one of the victims was 41 years of age. Also, my Mom died a most hideous death, Heidenhain Variant Creutzfeldt Jakob disease. Her symptoms resemble that of all the U.K. vCJD victims. She would jerk so bad at times, it would take 3 of us to hold her down, while she screamed "God, what's wrong with me, why can't I stop this." 1st of symptoms to death, 10 weeks, she went blind in the first few weeks. But, then they told me that this was just another strain of sporadic CJD. They can call it what ever they want, but I know what I saw, and what she went through. Sporadic, simply means, they do not know. My neighbors Mom also died from CJD. She had been taking a nutritional supplement which contained the following; vacuum dried bovine BRAIN, bone meal, bovine EYE, veal bone, bovine liver powder, bovine adrenal, vacuum dried bovine kidney, and vacuum dried porcine stomach. As I said, this woman taking these nutritional supplements, died from CJD. The particular batch of pills that was located, in which she was taking, was tested. From what I have heard, they came up negative, for the prion protein. But, in the same breath, they said their testing, may not have been strong enough to pick up the infectivity. Plus, she had been taking these type pills for years, so, could it have come from another batch?

CWD is just a small piece of a very big puzzle. I have seen while deer hunting, deer, squirrels and birds, eating from cattle feed troughs where they feed cattle, the high protein cattle by products, at least up until Aug. 4, 1997. So why would it be so hard to believe that this is how they might become infected with a TSE. Or, even by potentially infected land. It's been well documented that it could be possible, from scrapie. Cats becoming infected with a TSE. Have you ever read the ingredients on the labels of cat and dog food? But, they do not put these tissues from these animals in pharmaceuticals, cosmetics, nutritional supplements, hGH, hPG, blood products, heart valves, and the many more products that come from bovine, ovine, or porcine tissues and organs. So, as I said, this CWD would be a small piece of a very big puzzle. But, it is here, and it most likely has killed. You see, greed is what caused this catastrophe, rendering and feeding practices. But, once Pandora's box was opened, the potential routes of infection became endless.

No BSE in the U.S.A.? I would not be so sure of that considering that since 1990;

Since 1990 the U.S. has raised 1,250,880,700 cattle;

Since 1990 the U.S. has ONLY checked 8,881 cattle brains for BSE, as of Oct. 4, 1999;

There are apprx. 100,000 DOWNER cattle annually in the U.S., that up until Aug. 4, 1997 went to the renders for feed;

Scrapie running rampant for years in the U.S., 950 infected FLOCKS, as of Aug. 1999;

Our feeding and rendering practices have mirrored that of the U.K. for years, some say it was worse. Everything from the downer cattle, to those scrapie infected sheep, to any roadkill, including the city police horse and the circus elephant went to the renders for feed and other products for consumption. Then they only implemented a partial feed ban on Aug. 4, 1997, but pigs, chickens, dogs, and cats, and humans were exempt from that ban. So they can still feed pigs and chickens those potentially TSE tainted by-products, and then they can still feed those by-products back to the cows. I believe it was Dr. Joe Gibbs, that said, the prion protein, can survive the digestinal track. So you have stopped nothing. It was proven in Oprah Winfrey's trial, that Cactus Cattle feeders, sent neurologically ill cattle, some with encephalopathy stamped on the dead slips, were picked up and sent to the renders, along with sheep carcasses. Speaking of autopsies, I have a stack of them, from CJD victims. You would be surprised of the number of them, who ate cow brains, elk brains, deer brains, or hog brains.

I believe all these TSE's are going to be related, and originally caused by the same greedy Industries, and they will be many. Not just the Renders, but you now see, that they are re-using medical devices that were meant for disposal. Some medical institutions do not follow proper auto- claving procedures (even Olympus has put out a medical warning on their endescopes about CJD, and the fact you cannot properly clean these instruments from TSE's), and this is just one product. Another route of infection.

Regardless what the Federal Government in the U.S. says. It's here, I have seen it, and the longer they keep sweeping it under the rug and denying the fact that we have a serious problem, one that could surpass aids (not now, but in the years to come, due to the incubation period), they will be responsible for the continued spreading of this deadly disease.

It's their move, it's CHECK, but once CHECKMATE has been called, how many thousands or millions, will be at risk or infected or even dead. You can't play around with these TSE's. I cannot stress that enough. They are only looking at body bags, and the fact the count is so low. But, then you have to look at the fact it is not a reportable disease in most states, mis-diagnosis, no autopsies performed. The fact that their one-in-a- million theory is a crude survey done about 5 years ago, that's a joke, under the above circumstances. A bad joke indeed........

The truth will come, but how many more have to die such a hideous death. It's the Government's call, and they need to make a serious move, soon. This problem, potential epidemic, is not going away, by itself.
