RESUMO
A total of 350 stool samples from 196 males and 154 female children and neonatus admitted in Ibn-Sina hospital, Sirt, were examined from June 2001 to May 2002, to determine the prevalence of intestinal parasites. Intestinal parasitic infections were identified in 196 [56%] of children and neonates. No intestinal helminthic parasites were detected but 13 intestinal protozoan parasites were detected. The most prevalent protozoan was Entamoeba histolytica /E.dispar [36.57%]; Blastocystis hominis [12.57%], Giardia lamblia [10.29%], Isospora belli [3.14%] and Balantidium coli [0.86%], the latter was detected in non-Libyan children. The non-pathogenic ones were Entamoeba coli [15.14%], Endolimax nana [13.71%], Entamoeba hartmanni [4.29%], Chilomastix mesnilli [4.29%], Re-tortamonas intestinalis [3.43%], Dientamoeba fragilis [2%], lodamoeba butschlii [0.86%] and Trichomonas hominis [0.86%]. The result showed a significant difference exists between the prevalence of pathogenic and non-pathogenic protozoan parasites [P<0.05]. High prevalence of E. histolytica/ E. dispar followed by E. coli, E. nana, B. hominis and G. lamblia in both sexes of children, while the prevalence of other intestinal parasites were low in both sexes, significantly different existed in the prevalence of intestinal parasites between males and females children [t= 24.68; P<0.05]. Age groups had no effect on the prevalence of intestinal parasites [F= 0.66; P<0.05]. Significant differences existed in the prevalence between single and multiple infections with pathogenic protozoa. The socio-economic status of children parents revealed that highprevalence in children from medium socioeconomic status. The family size had no significant effect on the prevalence of the intestinal parasites
