A survey of histopathologic changes of intestine due to parasitic worm infestation in native poultry of Urmia area
The main purpose of this survey was evaluation of histopathologic changes occurs during parasitic infestation in native chickens of Urmia area. In this study 20 native chickens selected randomly and all sections of intestines were extracted after euthanizing. Then parasitic infestations were expected in parasitology laboratory and extracted parasites recognized after fixation. Selected samples from infested area of intestines sent to pathology laboratory and after fixation in formalin buffer 10% dyed with hematoxillin & Eosin staining method. In 10 infested cases, 6 nematodes and 4 cestodes infestations were seen that nematodes contain three species, Ascaridia galli, Subulura brumpti and Heterakis gallinarum. In addition 50% of all samples were infested. In histopathological examination, 1 case had congestion in serous connective tissue. Infiltration of inflammatory cells in mucosa in all 10 cases was found that in 9 cases these cells were mononuclear (lymphoplasmocytic) and in 2 cases were heterophilic. In 3 cases exfoliation of villi cells and in 1 case mucosal congestion in tip of villi was found. Other findings includes: necrosis in mucosa in 1 case and hyperplasia of mucosa and fibroses in one other case were found.
