CWD aka Scrapie???

[AT Hiker]

A very interesting study just published;

Characterization of Classical Sheep Scrapie in White-tailed Deer after Experimental Oronasal Exposure

All deer inoculated oronasally with classic sheep scrapie accumulated PrPSc with a tissue distribution similar to deer with chronic wasting disease (CWD).

In a nut shell; deer fawns were infected with scrapie and every single deer later tested positive. "whitetail deer are susceptible to the agent of classic scrapie from sheep, and differentiation from CWD may be difficult."

Sheep have dotted the American landscape....
Supposedly, scrapie infected sheep were identified in the mid 1700's UK, identified here in the 1940's. People have been eating sheep for quite some time, obviously, and so far no evidence exist that scrapie is zoonotic

CWD and Mad Cow Disease (MCD) ARE scrapie, in that they are all Transmissible Spongiform Encephalopathies (TSEs). That is just the names they use to differentiate between species. CWD in particular came about when mule deer were kept in a facility that had previously held sheep infected with scrapie. That is where the species jump first occurred. Creutzfeldt-Jakob Disease (CJD) is a nearly identical disease in humans but is naturally occurring (not transmissible from human to human). Creutzfeldt-Jakob Disease variant (CJDv) is the human form picked up from eating beef infected with MCD.

Actually, scrapie was described in the UK over 1,000 years ago by early sheep herders.

interesting to me that all the deer fawns got CWD from the sheep brain scrapie inoculant, but none from the goat brain scrapie inoculant.

According to the article I shared, they can tell a difference within the species based on molecular weight, where the sample was taken from and incubation time frames.

And the scrapie infected elk presented a different profile from the whitetail supporting "the theory that the identification of CWD in Norway is not likely due to exposure to scrapie-infected sheep since the CWD case from Norway has a profile similar to that of North American elk CWD rather than the lower pattern of sheep scrapie "

Most likely came from elk transported from elk farms in central Canada
