[Cyclospora cayetanensis: review of an emerging intestinal pathogen].
Cyclospora cayetanensis is an emerging pathogen. It is a new human coccidian agent of intestinal disease. Twenty years ago, the first known human cases of cyclosporiasis were reported in the medical literature. Cyclosporiasis occurs in persons of all ages and either in immunocompetent or immunocompromised hosts. The most characteristic feature of this infection is a syndrome of acute or chronic diarrhea. This parasite has a world-wide distribution. In previous reports, Cyclospora cayetanensis was associated with prolonged diarrhea in travellers, returning from developing countries. However, Cyclospora infection has recently been reported in non travellers in the United States and Canada. Cyclospora can be transmitted by ingestion of water or food contaminated with oocysts. The life cycle of Cyclospora cayetanensis is not fully known. Diagnosis of cyclosporiasis is made by direct examination of stool samples. To date, oral trimethoprim-sulfamethoxazole is the only effective treatment for Cyclospora infection.
