Prevalence of Intestinal Coccidial Infections among Different Groups of Immunocompromised Patients.

BACKGROUND: considerably has increased, since immunodeficiency virus (HIV) rapidly disseminated. In addition, cancer patients are highly susceptible to opportunistic infections. This study aimed to estimate the prevalence of cryptosporidiosis and isosporiasis in immunocompromised patients in Tehran. METHODS: This study carried out on patients admitted to Imam Khomeini hospital during 2013-2014. Stool samples collected from 350 immunocompromised patients. Formol-ether concentration was performed for all stool samples. Zeil-Neelsen technique was applied to stain the prepared smears and finally, all slides were examined by light microscope. RESULTS: oocysts were detected in 4 (1.1%) samples consisting 2 HIV+/AIDS patients, one patients suffering from malignancy and one patients with other immunodeficiency diseases. CONCLUSION: are the most prevalent gastrointestinal parasitic protozoans that infect a broad range of individuals, particularly those patients who have a suppressed or deficient immunity system.
