Three hundred and eighty samples of house flies were collected randomly from garbage of houses and examined both external surface and digestive tract to isolate and identify parasites. 309 out of 380 samples were infected with parasites (81.31%), infection percentage with Protozoa (43.68%) while infection percentage with worms eggs (37.63%), as well as infection percentage with ectoparasites (52.36%) While infection percentage with endoparasites (28.94%). Ten species of parasites recorded in this study represented seven species of parasites which were isolated from external surface of house fly included two species of protozoa cyst were Entamoeba histolytica (10.35%) and Giardia lamblia (7.76%) and five species of worm's eggs were Ascaris lumbricoides (15.53%), Enterobius vermicularis (14.23%), Hymenolepis nana (7.11%), Trichuris trichiura (5.82%) and Strongyloides sp. (3.55%), in addition three species of protozoa oocyst which isolated from digestive tract were Cryptosporidium parvum (14.88%), Cryptosporidium muris (12.29%) and Cyclospora cayetanensis (8.41%).
