Study on the parasitic infections of native chickens of Ilam city, Ilam ,Iran

Chickens may be infected with parasitic, viral and bacterial infections. The aim of this study was to determine the fauna, prevalence and severity of internal and external parasites of Chickens inIlam. In this study, 60 chickens were necropsied. Internal organs, feather and leg skin chips were examined. Feather, leg skin chips, gastrointestinal tract and femur muscle was infected withparasites. The identification of Nematodes was possible after they were cleared inlactophenol and it was possible to identify the cestoda after schneider acetocarmine staining. Isolated parasites from the feather, feathers follicle and leg skin chips were prepared and then examined. To distinguish blood and mucosal parasites, 2 smears and 1cc blood was taken from wing vein. Femur muscle was examined by dob smear while cecum, small and large intestine were smeared and then all were stained with geimsa. A smear from the trachea, trachea bifurcate, and the end of large intestine was prepared and then stained with Ziehl-Neelsen method. Prevalence and fauna of cestoda include: Raillietina echinobothrida 26.6%, Raillietina tetragona 26.6%, Raillietina cesticillus 13.3%, Choanotaenia infundibulum16.6%, Cotugnia digonopora 5. .Nematoda, Acuaria spiralis3.3%, Cheilospirura hamulosa 1.6%, Ascaridia galli 30% , Heterakis gallinarum 16.6%, and external parasites: Menopongallinae 55%, Goniodes spp. 18.3%, Lipeurus caponis 53.3% Menacanthus stramineus 58.3%, Goniocotes gallinae 81.6%, Cnemidocoptes mutans 23.3%, Grallobia spp. 33.3%.
