Abstract

A study of pulmonary diseases in the slaughtered cattle (n = 125) of Mymensingh town was conducted to study pathological findings using the standard methods from September 2001 through April 2002. The pulmonary lesions observed in this study included congestion, emphysema, anthracosis, pleuritis abscess and hemorrhage. The histopathological findings of congestion were characterized by hemorrhage, a large number of leukocytes infiltration in the lumen of the alveoli, bronchitis, bronchiolitis, proliferation of fibrous connective tissue and hyperplasia of bronchiolar epithelia. Histopathologically, emphysema was identified by the distended alveoli with thin and atrophied alveolar walls. In anthracosis, carbon particles were found in stroma and alveolar lumen. In pleuritic lesions, there was a proliferation of fibrous connective tissue along with the infiltration of mononuclear reactive cells. Abscesses were characteristic of the accumulation of neutrophils surrounded by immature fibroblasts forming a capsule like structure.
