Six human cyclosporiasis: with general review.
Cyclospora cayetanensis is an emerging coccidian pathogen known in animal since a long time, but recognized in human in last two decade. The present study of cyclosporiasis specified its characteristic features. An epidemiological, clinical and biological retrospective study was carried out on 6 patients, 24 to 67 years old, who complained of diarrhea and weight loss, after a travel abroad. The only pathogenic agent found in every patient was Cyclospora cayetanensis. The patients returned back from Asian countries and from Madagascar. They were cured by Trimethoprim-sulfamethoxazole (TMZ). Diarrhoea was the main symptom of infection by C. cayetanensis. Undoubtedly, transmission occurred by the oro-fecal route, and/or by consumption of infected water or foods. Diagnosis was asserted, recovery of this protozoan parasite in the stools samples. TMZ proved to be the most effective and possibly replaced Ciprofloxacine. The prophylaxis recommended control measure of water supply and foods. Cyclospora should be considered in the assessments of patients with unexplained prolonged diarrhoea, if the investigation for bacterial and parasitological diarrhoea or the traveler's diarrhoea were negative.
