Aim. A case-control study was conducted to determine the prevalence of G. lamblia, Cryptosporidium, spp and E. histolytica/dispar in diarrheal children at Yirgalem Hospital from February 2011 to August. Subjects and Methods. A total of 230 children participated in the study of which 115 (50%) were cases and 115 (50%) were controls. A single stool sample was collected and examined by direct saline wet mount, formol-ether concentration, and modified Ziehl-Neelsen. Results. Eighty-four (36.52%) were positive for at least one intestinal parasites (57 (49.56%) from diarrheal children and 27 (23.47%) out of nondiarrheal children). The prevalence of G. lamblia, Cryptosporidium spp, and E. histolytica/dispar was 15.65%, 9.56%, and 4.35% in children with diarrhea and 1.74%, 5.21%, and 1.74% in those without it, respectively. Cryptosporidium spp and E. histolytica/dispar revealed higher infection in males (10.81% and 5.4%, resp.) than in females (7.32% and 2.43%, resp.). G. lamblia infection was higher in females (29.27%) than in males (8.11%). Cryptosporidium spp infection was higher in the age groups of ≤4 years old (53.84%). Significant difference was seen between 10 and 13 (7.69%) years old. Higher prevalence of E. histolytica/dispar was found in 5–9 years (85.71%) than ≤4 years old (14.28%). Conclusion. Cryptosporidium spp, E. histolytica/dispar, and G. lamblia were higher in children with diarrhea than in those without it.
