We examined the samples using direct smear, formol-ethyl acetate concentration, Agar-plate culture and Ziehl-Neelsen staining technique. Results: The frequency of intestinal parasites were: Blastocystis hominis 12.8%, Giardia lamblia 2.5%, Entamoeba coli 4.8%, Iodamoeba butschlli 0.9%, unknown 4 nuclei cysts 0.4%, Endolimax nana 3.2%, Chilomastix mesnili 0.4%, Strongyloides stercoralis 0.1%, Hymenolepis nana 0.2% and Taenia saginata 0.2%.
