Background: Cyclospora cayetanensis is a food-borne coccidian parasite that causes cyclosporiasis in humans and possibly in other animals. It presents with watery diarrhea and other related symptoms. Since detection of oocysts may be difficult with histological stains, a negative result should not exclude the possibility of C. cayetanensis. PCR methods can achieve more sensitive detection of the parasite.
