The reflection of control programs of parasitic diseases upon gastrointestinal helminthiasis in Dakahlia Governorate, Egypt.

The study area included Mansoura city as an urban area and Gogar village as a rural area. One thousand individuals were randomly selected from each area. Different methods of stool examination, perianal swab and urine examination of all participants revealed that the incidence in Mansoura city was in a descending order Heterophyes heterophyes 6.4%; Enterobius vermicularis 3.9%; Hymenienolepis nana 2.2%; Schistosoma mansoni 0.5%; Trichostrongylus colubriftormis; Strongyloides stercoralis and Fasciola sp. were recorded as 0.2% of each. Taenia saginata, Ascaris lumbricoides and Trichocephalus trichiuris were recorded as 0.1% of each. Neither Ancylostoma duodenale nor Hymenolepis dimninuta was recorded. In Gogar, the parasitic infection was H. hetephyes 4.5%; E. vermicularis 4.1%: H. nana 3.3%; S. mansoni 1.6%; T. colubriformis 0.9%; S. stercoralis 0.5%. Fasciola sp. 0.4%; T. saginata, A. lumbricoides, H. diminuta, A. duodenale and T. trichiuris were recorded as 0.1% of each. None S. haematobiumn was detected in both areas. So, the infection rates of H. heterophyes, E. vermicularis, H. nana S. mansoni, Fasciola sp., T. colubriformis and S. stercoralis were relatively high the rural than in urban area. This was not surprising since the socioeconomic, hygienic conditions and medical services were relative high in the city than in the village. No doubt, the identifications of parasitosis pave the way for feasible treatment and control measures.
