2. infection or infestation with parasites.

Patient discussion about parasitism

Q. is an Amoeba dangerous?? and how can i get rid of it? my son is in Peru, he called and told me he got an Amoeba..i have no idea if it's dangerous or not, and how to get rid of it. and what kinds of food he needs to avoid.I'll appreciate help!

A. oooo...an Amoeba is a nasty one...but not so dangerous! it's a one celled parasite which gets into your body if you eat in restaurants that the cook doesn't wash hands after going to the bathroom..it multiplies in your intestine and makes you diarrhea like hell. but if you'll treat it right it will go away as nothing happened. if you don't it can give you liver cyst. and that's not good. he should see a Dr.

If, as is expected for many microparasites of invertebrates, the host-parasite interaction produces cyclic or chaotic population dynamics in the host (Anderson and May 1981, May 1985a) and/or host and parasite are engaged in a long-term coevolutionary relationship (May 1985b), then communities strongly influenced by the host may exhibit highly variable configurations.

A growing body of the parasitological literature focuses on mechanisms by which microparasites (bacteria, viruses, protozoa, and fungi) reduce host fitness, primarily because of their role in regulating natural populations of many animals, including humans (Park 1948, Anderson and May 1981, May 1983, Ewald 1994).
