I read an article several years ago about a veterinarian who had to quit his practice. He was kicked by a horse and subsequently had his spleen removed. His doctor told him to avoid cats (or dogs, can’t remember which) because they carried a virus/parasite/other bug that would kill him.
I know that the spleen plays a role in the immune system, but I’m trying to come up with the name of this particular disease because 1) my sister thinks I’m nuts; 2) it’s starting to drive me that way; and 3) I’m having no luck with net searches.
Some of the highlights: Toxoplasmosis. “Cat scratch fever”, (Bartonellosis). Kennel cough (Bordetella). Psittacosis.
Obviously a veterinary practice is a bad place for someone with a severely compromised immune system.
There’s one more thing. Dogs can get canine parvovirus. People can get another kind of parvovirus, called “fifth disease”, but it’s a different kind from CPV, and you can’t get it from your dog. Probably if you have a severely compromised immune system, it could be very dangerous. It’s possible that the article you read was written by someone who didn’t understand the difference between the two parvos.
