Abstract
Cyclospora cayetanensis is an intestinal coccidian parasite that causes significant diarrhoeal illness in both immunocompetent and immunocompromised hosts.
Despite, the diagnosis of Cyclospora cayetanensis infection is difficult because of its frequent misdiagnosis with Cryptosporidium
and its difficult staining properties, yet it is very important because diarrhea caused by Cyclospora cayetanensis can be treated by drugs in contrast to Cryptosporidium that is difficult in treatment.
The present study aimed to diagnose C. cayetanensis infection in stool samples of immunocompetent and immunocompromised patients with diarrhoea, to evaluate different methods used for diagnosis of Cyclospora cayetanensis to determine the most suitable method for its diagnosis and to test the susceptibility of laboratory animals to infection with C. cayetanensis namely, albino mice.
The stool samples from the following five groups of diarrhoeic patients were examined for Cyclospora cayetanensis:
• Group I: 66 cancer patients under chemo or radiotherapy.
• Group II: 38 uraemic patients.
• Group III: 23 patients with chronic liver cell failure.
• Group IV: 32 malnourished children.
• Group V: 21 diarrhoeic immunocompetent patients
