Objective: to determine the prevalence and type of intestinal parasites in HIV infected and uninfected patients with diarrhea.
Design: A cross-sectional study was conducted at Gondar University hospital, Northwest Ethiopia, between March 2003 and October 2004.
Patients and methods: A total 312 consecutive diarrheic patients were included in the study. Stool specimens were collected and examined for intestinal parasites following direct, formol-ether concentration and modified acid fast staining methods.
Results: Among the patients, 63.8% were found to be HIV seropositive. The prevalence of intestinal parasites in HIV seropositive and seronegative diarrheic patients was 30.6% and 33.6%, respectively. The most prevalent parasites were Strongyoides stercoralis (9.0%) and Entamoeba histolytica (8.3%) followed by Ascaris lumbricoides (5.4%) and Cryptosporidium species (5. 1%).
Conclusion and recommendation: The prevalence of intestinal parasites in diarrheic patients was very high. Institution of appropriate intervention measures are needed to reduce morbidity in such patients.
