title: Co-infection of Giardia intestinalis and Cyclospora cayetanensis in an immunocompetent patient with prolonged diarrhea: case report.
abstract: Cyclospora cayetanensis is an agent of emerging infectious disease, and a recognized cause of diarrhea in some patients. Also, the flagellated protozoan, Giardia intestinalis, induces a diarrheal illness of the small intestine. Cases of cyclosporiasis are frequently missed, primarily due to the fact that the parasite can be quite difficult to detect in human fecal samples, despite an increasing amount of data regarding this parasite. On the other hand, G. intestinalis can be readily recognized via the microscopic visualization of its trophozoite or cyst forms in stained preparations or unstained wet mounts. In this report, we describe an uncommon case of co-infection with G. intestinalis and C. cayetanensis in an immunocompetent patient with prolonged diarrhea, living in a non-tropical region of Turkey.
