Incidence of the Pathological lesions in Lung and Associated Lymph Nodes of Slaughtered Cattles in Babylon Abattoir

Abstract

O NE OF the governorates of Iraq, Babylon is well-known for its agricultural and animal industries. The purpose of the study was to offer information on various pathological respiratory disorders affecting cattle and their effects on resources of animal. (30) samples of slaughter cattle (both male and female) were collected from the Al-Hashymia and Al-Qasim abattoirs at Babylon governorates. The morphological alterations in the lung and associated lymph nodes were examined postmortem, and tissue samples were collected, and finally sent for histopathological analysis in a plastic container with 10% formalin. The postmortem examination of the lung 60% revealed the existence of several hydatid cysts, many of which were big cysts measuring 1 to 5 cm in diameter. 16.7% of the samples had granulomatous lesions, which were visible as thick, yellow caseated material, which was surrounded by a thick connective tissue capsule. Additionally, there are vast fibrotic areas, 23% atrophy, and gray staining in the pulmonary lymph nodes. The findings of the lung's histologically included substantial pulmonary blood vessel congestion. 6.7% Papillary projection is the result of hyperplasia of the epithelial cells lining the bronchioles. There was hemosiderin-loaded macrophages (26.7%) and follicular hyperplasia with a spherical follicular center surrounded by broad lymphocyte mantles in the exanimated lymph node with severe necrosis (16.7%).
