The problem is they generally don't get autopsies, so the imaging studies are based on extrapolation.
The most recent stuff I've read is years old now but insisted that there was no way to sterilize equipment to be used in surgery. Now autopsy equipment theoretically won't be used in surgery so there should be no risk of contagion to a live patient.
That depends on whose data you go by. Yes there are many different names depending upon species, however direct trans-species inoculation universally results in disease. The variances is manifestations may still be the same causative agent with variances explained by infectious load, age of subject and varying degrees of species resistance.
Don't discount there have been cover-ups.For years the UK insisted that their Scrapie outbreak was Hoof and Mouth disease. There was a case that I know of of a sudden outbreak of what was officially called, "Early onset, rapidly progressive Alzheimers," in Eastern Ky back in the 90's. A lot of people were dead within 2 years. That whole thing was weird. They used to have a festival of Burgoo (brain stew, usually from wild game. Nowadays they use skeletal meat). It never really made the news because the rest of America didn't care what happens in Eastern Ky. The few articles I saw claimed it was the result of inbreeding. I didn't see any actual articles in medical journals about it, but physicians were talking about it amongst ourselves. There was some grant or gift or some sort, some people said it was the life insurance companies, but others said their beloved ones didn't have life insurance, some said the funeral homes, the story was never the same twice, anyway there was a temporary spate of greatly reduced cost for cremations
yep, not worth it because we really don't know what we don't know
