www.livescience.com/12951-10-infectious-diseases-ebola-plague-influenza.htmlBacteria and viruses that are deadly to one type of creature can evolve quickly to infect another. While the swine flu outbreak is the latest example, a host of infectious and deadly diseases have hopped from animals to humans and from humans to animals. The cross-species infection can originate on farms or markets, where conditions foster mixing of pathogens, giving them opportunities to swap genes and gear up to kill previously foreign hosts (i.e. you). Or the transfer can occur from such seemingly benign activities as letting a performance monkey on some Indonesian street corner climb on your head. Microbes of two varieties can even gather in your gut, do some viral dancing, and evolve to morph you into a deadly, contagious host.Diseases passed from animals to humans are called zoonoses. There are more than three dozen we can catch directly through touch and more than four dozen that result from bites. But disease-carrying parasites are not picky about hosts. Human diseases can decimate animal populations, too, from such well-meaning activities as ecotourism. ------------------------------------ "Ecotourism" ----- a new made up word for this new microbe carrying world we live in.

Unreal. It sure use to seem like there weren't so many zoonotic diseases before, or maybe I just didn't know better. It seems anymore...so much is being able to be mutually compatible. That's scary.
And yep...Ecotourism, what a word.

Thank you very much. Now that was a cool read. One of the best I have seen on this board. Every time I hear a doctor ask "Have you been out of the country?" I just want to kick the hell out of them. Thanks again
Mother earth can out do anything we come up with. Humans may become extincted but the earth will still keep turning.
