Cryptosporidiosis, isosporiasis, cyclosporiasis, and sarcocystosis are diseases caused by protozoa of the phylum Sporozoa, class Coccidea, order Eimeriida. All are obligate intracellular parasites of intestinal epithelial cells. Cryptosporidium sp, Isospora belli and Cyclospora cayetanensis complete their life cycles within a single host. They cause self-limited or prolonged diarrhea, depending on the hosts immune status. In contrast Sarcocystis requires two host species. Compared to other coccidia, Cryptosporidium sp are less host or organ specific, resist antimicrobial agents and produce auto infection, features more closely related to gregarines.
