Abstract :
The prevalence of Giardia lamblia and Entamoeba histolytica/E.dispare were screened among 513 children aged less than 12 years in Al-Shulaa and Al-Khadimya - Baghdad, to evaluate the relationship of some factors (gender, age, grade and type of drinking water) with the prevalence of these two intestinal protozoal parasites, this study was done during the period from the beginning of April 2009 till the end of March 2010, in human.The study revealed that the total rate of (G.lamblia and E. histolytica/ E.dispare) infection was (13.64%), the infectivity rate of G.lamblia was higher than the infectivity rate of E.histolytica/ E.dispare as their rate was (10.72%) and (2.92%) respectively, and there was no significant relation (p≤0.05) between infectivity rate of these parasites and each of gender, age and grade (school and preschool) while there were very high significant relation between the type of drinking water and infectivity rate of both (G.lamblia and E. histolytica/ E.dispare) the maximum infectivity rate of (G.lamblia , E.histolytica/ E.dispare) was observed in patients who consumed tap water (17.56%) while patient who consumed the other kind of drinking water showed the minimum infectivity rate which was (3.49%).
