ARCHELLI, Susana  and  KOZUBSKY, Leonora Eugenia. Cyclospora cayetanensis: An emerging coccidian. Acta bioquím. clín. latinoam. [online]. 2012, vol.46, n.4. ISSN 0325-2957.

Cyclospora cayetanensis is a coccidian protozoon with several prevalence worldwide that causes watery and voluminous diarrhea conditions both in immunocompetent and immunocompromised patients. In the latter, apart from originating more severe enteric diseases, it can occur with billiary involvement. Its distribution is cosmopolitan, with soil, water and contaminated food, especially consumption of raw vegetables, playing an important role in its transmission. Man, the only reservoir recorded so far, eliminates immature oocytes in feces, which evolve in the environment becoming infective- mature oocytes. Like other coccidians, it presents a complex evolutionary cycle with sexed and unsexed forms of reproduction in a single host. Diagnosis is mainly based on findings of variable acid-alcohol resistant variables in feces. Molecular methods have been developed for its detection in fecal samples and in environmental and food samples as well.
