Other protozoal intestinal diseases (A07)

Clinical Information for Other protozoal intestinal diseases (A07)

Isosporiasis - Infection with parasitic protozoa of the genus ISOSPORA, producing intestinal disease. It is caused by ingestion of oocysts and can produce tissue cysts.

Giardiasis - An infection of the SMALL INTESTINE caused by the flagellated protozoan GIARDIA. It is spread via contaminated food and water and by direct person-to-person contact.

Balantidiasis - Infection by parasites of the genus BALANTIDIUM. The presence of Balantidium in the LARGE INTESTINE leads to DIARRHEA; DYSENTERY; and occasionally ULCER.

Cyclosporiasis - Infection with parasitic protozoa of the genus CYCLOSPORA. It is distributed globally and causes a diarrheal illness. Transmission is waterborne.

Cryptosporidiosis - Intestinal infection with organisms of the genus CRYPTOSPORIDIUM. It occurs in both animals and humans. Symptoms include severe DIARRHEA.

Coccidiosis - Protozoan infection found in animals and man. It is caused by several different genera of COCCIDIA.

Isospora - A genus of protozoan parasites found in the intestines of birds, amphibians, reptiles, and mammals, including man. The oocysts produce two sporocysts, each with four sporozoites. Many species are parasitic in wild and domestic animals.

Coccidia - A subclass of protozoans commonly parasitic in the epithelial cells of the intestinal tract but also found in the liver and other organs. Its organisms are found in both vertebrates and higher invertebrates and comprise two orders: EIMERIIDA and EUCOCCIDIIDA.

Cyclospora - A genus of coccidian parasites in the family EIMERIIDAE. Cyclospora cayetanensis is pathogenic in humans, probably transmitted via the fecal-oral route, and causes nausea and diarrhea.
