How is mad cow disease and microsporum gallinae transmitted through animals?

Answer 1

M. gallinae is a skin fungus rather like ringworm or athletes foot, that affects chickens. Looks like it transmits to mammals as well, although only rarely to humans. Skin contact would be the means of transmission there.
'Mad cow' is a prion disease. I'm not sure how they normally spread within a species, but prion diseases like scrapie are communicable, maybe in the saliva? Humans pick up 'Mad cow' and similar prion diseases (like the one from squirrel brains) by eating central nervous system (especially brain) tissue from infected animals. Since the US gov't pretty much takes a "you're-on-your-own" approach to food inspection these days, that means almost any kind of processed meat like hamburger or hot dogs can theoretically be infected by CNS tissue, potentially including prions. In practice, so far there have been no known outbreaks here in the US like in the UK, although there have been a few reported cases of cattle infection. Of course, with a lag time from exposure to symptoms that might be a decade or two, it's hard to know for sure. Personally, I'd be more concerned about E. coli contamination. Just for fun, read some Upton Sinclair - we seem to be heading back into The Jungle...

Answer 2

Mad Cow Disease was spread by feeding bits of infected animals to the cows. Yes, they ground up bits of dead cows and gave it to other cows.
