Okay, putting aside the desire to disbelieve that this actually goes on IRL… Ewww!
Is there any evidence that some pretty awful diseases can (or have) been transmitted between animals and the very very very sick people who love them too much?
And again… ewwwwwwww…<off to shower mental image out with bleach>
Ringworm is zoonotic. I suppose the location of the lesion may fit with your question. Brucellosis is a disease spread from animal to animal via sexual contact. Human infections are rare, but do occur.

When working in a vet clinic, I once had the task of washing three kittens who had diarrhea and ringworm (the poor things. Adorable as hell but they weren’t very healthy.) I wore gloves, of course, but kittens have very sharp claws, and they seem to grow sharper when the cat is being bathed. I ended up getting ringworm just in time for a vacation to Portugal (and my broken Portuguese made getting treatment more difficult!)
So I guess I got ringworm because I love kittens too much.
There is some thought that HIV most likely came from SIV via the green monkey. No one knows how it jumped species exactly, but, seeing as how AIDS is sexually transmitted…
To be pedantic, that’s one of the ways it can be transmitted. Specifically, it’s present in decent quantities in blood and semen, and activities like a blood-drawing fight with a monkey, eating rare monkey steaks, etc., might also be main ways that a mutating SIV virus might have jumped species.[/hijack]
So if monkeys had guns, AIDS might never have happened…
The thought was that people were eating the raw meat( brains) of green monkeys. However, I believe that link was never proved
Koalas carry chlamydia… They are kinda cute, but…
Which strain of HIV are we talking? HIV-1 and HIV-2 came from separate zoonosis events. I’ve read that the most plausible mode of transmission was probably from the bushmeat trade. HIV-1 came from chimps, though, not monkeys. And HIV-2 (a much rarer, somewhat less virulent form mostly confined to Africa) came from a monkey called the sooty mangabey.
Koalas have bifurcated reproductive organs.
That is, the male Koala has a slingshot sans rubber band, with the lady possessing compatable parts.
So, anybody “getting it on” with one would have to…oh yeah, Australia was colonized by convicts, wasn’t it?
