Cyclosporiasis is infection with the protozoan Cyclospora cayetanensis. Symptoms include watery diarrhea with gastrointestinal and systemic symptoms. Diagnosis is by detection of characteristic oocysts in stool or intestinal biopsy specimens. Treatment is with trimethoprim/sulfamethoxazole. When freshly passed in stools, the oocyst is not infective (thus, direct fecal-oral transmission cannot occur; this differentiates Cyclospora from another important coccidian parasite, Cryptosporidium).In the environment , sporulation occurs after days or weeks at temperatures between 22C to 32C, resulting in division of the sporont into two sporocysts, each containing It usually causes a watery diarrheal illness that can last anywhere from nine to 43 days if left untreated. The diarrhea can last for 18 weeks and be associated with abdominal pain, nausea, vomiting and anorexia. Cyclospora is a parasite that is composed of one cell.

Cyclospora cayetanensis is a single celled protozoan that causes an infection in the gastro intestinal tract of the human body. It mainly occurs in semitropical and tropical regions. TMP-SMZ therapy significantly decreases the duration of oocyst excretion. However, the diagnosis and treatment of intestinal helminth infections have not been changed much, and the traditional microscopic method can be used for their diagnosis.

Cyclospora cayetanensis is a parasite that can cause intestinal distress when consumed through tainted water or food products. Its full name is Cyclospora cayetanensisa, and it has a life cycle that involves both sexual and asexual reproduction.The part of the cycle in man is the ingestion of sporulated oocysts that pass through the GI tract where the sporocysts break open in the small intestine and release It mainly occurs in semitropical and tropical regions.
