IBNC Tauopathy or TSE Prion disease, it appears, no one is sure

Greetings Plos et al,

in reference to;

‘’A Naturally Occurring Bovine Tauopathy Is Geographically Widespread in the UK’’

I kindly wish to comment please, as follows.

I was stunned by this report.

This Research Report should have been titled ;

‘’It Appears A Naturally Occurring Bovine Tauopathy Is Geographically Widespread in the UK’’

>>>Thus IBNC _appears_ to be the first naturally occurring and geographically widespread tauopathy in a species other than humans.<<<

>>>IBNC _appear_ to lack intracellular neurofibrillary tangles,<<<

>>>Thus IBNC _appears_ to be the first naturally occurring and geographically widespread tauopathy in a species other than humans<<<

>>>IBNC appears to be a complex proteinopathy with evidence for additional secondary accumulation of alpha synuclein, ubiquitin, and possibly PrP [5]. <<<

>>>however, it appears to represent a naturally-occurring predominantly 3R tauopathy in a non-primate species.<<<

>>>In the absence of any specific aetiological cause of IBNC yet identified, and based on the existing epidemiology and presence of P-tau we have considered the possibility that IBNC might also have a significant environmental component. Epidemiological investigations to explore usage of herbicides, insecticides, parasiticides and other chemicals used in agriculture would be helpful in future investigations of IBNC and might provide further insight into some causes of neurodegeneration in man.<<<

This is supposition at best in my opinion, and at worse, I will refrain from comment.

Too many _appears_ , appears this, appears that.

Too many _In the absence of any specific aetiological cause of IBNC yet identified_

is this what science has come to?

has science become some entwined with corporate special interest, do we change science now?

I believe that is far too early to rule out IBNC as a Transmissible Spongiform Encephalopathy TSE prion disease, either of typical or typical strain.

it can be argued that there is potential for Alzheimer’s to be a low dose TSE Prion disease ;

what about horizontal and or vertical transmission of an atypical strain of the BSE TSE prion disease into a low dose that is not detectible with TSE Prion testing to date?

what about a completely different strain, another atypical, of the TSE prion disease, to low to detect to date, and I stress to date?

to abandon the TSE prion and IBNC link there from would be foolish in my opinion.

SEAC, FatPride, BSE Inquiry, have never found a link to pesticides, or OP’s, or metals, as a _cause_, to any TSE prion disease.

I have also followed the metals, pesticide debate as a cause for the TSE prion disease. to date, this has proven to be fruitless for any _cause_ of the TSE prion disease. not to say the potential for these factors for one to be more susceptible to a TSE prion from surrounding environmental factors i.e. surrounding TSE prion exposures from the various routes and sources of the TSE prion disease (see metals and pesticide i.e. FatePride towards the bottom). from Mark Purdey and his research, to a farmer with BSE that treated his kids with OP’s for head lice, and nothing scientific to date has confirmed a link to the TSE prion disease as a _cause_.

We MUST not abandon transmission studies, and or any link to the TSE prion disease.

IT appears, in the absence of any scientific link to any specific herbicides, insecticides, parasiticides and other chemicals to date to IBNC, to just explore other options instead of the transmission studies to prove one way or the other whether or not the IBNC or BBD or whatever you want to call this, while ignoring the existing epidemiology and knowledge of the TSE prion disease with the primitive TSE prion testing to date, it appears all this would be foolish, it appears this would be very questionable, in my opinion. ...

Atypical prion proteins and IBNC in cattle DEFRA project code SE1796 FOIA Final report These findings together might suggest an additional family of neurodegenerative diseases where the infectious form of PrP is not readily detected by our current diagnostic tests. IBNC is likely to represent a subset of this group of cattle. Based on these data, our overall conclusion is that a second type of BSE is unlikely to have co-existed at a high prevalence with the classical form in the cattle population during the UK epidemic.

Subject: Idiopathic Brainstem Neuronal Chromatolysis (IBNC): a novel prion protein related disorder of cattle?

Greetings Honorable Science Advisory Council et al @ DEFRA,

I wish to ask a question about something I have seen no updates on, that concerns me.


I have seen nothing in the scientific literature updated on this in years, since around 2008, then it was like it fell off the face of the earth ?

can you please give me some sort of update on the IBNC BSE science to date ?

how many cases of IBNC BSE have been detected ?

is there an ongoing surveillance for this the IBNC BSE, and are the BSE test even capable of detecting it ?

could the USA and or North America even detect, if they were even looking for it ?

latest studies, if any more since "All of the 15 cattle tested showed that the brains had abnormally accumulated PrP" ?

thank you,

kind regards, terry
