Cyclospora cayetanensis oocysts are spherical, 7.5-10 µm in diameter and unsporulated when passed in feces. Sporulation in the environment is temperature-dependent and may take one to several weeks for an infective oocyst to contain two sporocysts, each containing two sporozoites. See more Cyclospora cayetanensis is a coccidian protozoan. It appears that all human cases are caused by this species; no animal reservoirs for C. cayetanensis have been identified. See more When freshly passed in stools, the oocyst is not infective (thus, direct fecal-oral transmission cannot occur; this differentiatesCyclospora from another important coccidian parasite, Cryptosporidium).
