Abstract
In a study on parasites of stray dogs in Ismailia city, 50 stray dogs of different sexes and ages were examined for ectoparasites then necropsied for endoparasites. The detected parasites were six ectoparasite species and 20 helminths (14 trematodes, two cestodes and four nematodes). The total prevalence of ectoparasites was 100%. The most prevalent ectoparasite was Ctenocephalides canis (100%). Other detected ectoparasites were Ctenocephlides felis, Echidnophaga gallinacea flea, Rhipicephalus sanguineus, Heterodoxus spiniger and Hippobosca longipennis fly.The total prevalence of helminths was 100% with trematodes (36%), cestodes (100%) and nematodes (34%). Of the recorded 14 trematodes, Pygidiopsis summa and Ascocotyle rara were recorded for the first time in Ismailia Province and this may be the first time to record these two trematodes among the Egyptian dogs. The most prevalent trematode was Pygidiopsis genata (20%). Mesostephanus spp. had the highest mean intensity of 95.5 (18-170) flukes/dog. The detected cestodes were Dipylidium caninum (100%) with mean intensity of 62.3 (2-189) worms/dog and Taenia hydatigena (10%) with mean intensity of 2 (1-4) worms/dog. The recovered nematodes were Toxocara canis (20%) with mean intensity of 7.3 (3-15), Toxascaris leonina (10%) with mean intensity of 4.4 (2-8), Spirocerca lupi (10%) with mean intensity of 5.6 (3-8) and Rictularia affinis (8%) with mean intensity of 1.8 (1-2) worms/dog
