Because many people with HIV are treated with antibiotics, they are at particular risk for developing C. difficile diarrhea. The diarrhea is often profuse, watery, and foul-smelling, and it may contain mucus or blood. If left untreated, it can lead to serious illness. It s usually treated with metronidazole, vancomycin, or neomycin. Parisitic Infection Amoeba Microscopic, parasitic amoeba can cause severe diarrhea.
People usually become infected by drinking contaminated, unpurified water.
Amoeba can also be transmitted sexually if there is any sort of oral contact with feces. An amoebic infection requires treatment with two antibiotics, metronidazole and iodoquinol, in order to kill and remove both the adult amoeba and amoebic cysts. Giardia Giardia is a water-borne parasite that inhabits streams and wells and can be found in unpurified drinking water. Like amoeba, giardia can be transmitted sexually if there is any sort of oral contact with feces. Treatment usually involves metronidazole.
