Pulmonary and Hepatic lesions in slaughtered sheep in Mosul city

The aim of study was designed to determine the prevalence rates, gross and histopathological lesions of lungs and livers in sheep slaughtered house at Mosul city. 9127 slaughtered sheep were examined During April and May 2014. 1235 infected carcasses were observed harboring different pathological gross lesions in the lungs and livers with 10.26% and 3.26% prevalence rates. The highest prevalence rates of gross pathological lesions of the lung were pneumonia of various types and the lightest was observed in T.B-like lesions was 3.34% and 0.04% out of total slaughtered sheep, respectively. In the affected livers, peak and the lowest prevalence of gross lesions were 0.77% for fascioliasis and 0.14% for enlarged and pale livers out of the total sheep ante-mortem inspected, respectively. However in the lungs, different rates of histopathological lesions were recorded for interstitial pneumonia, edema, emphysema, bronchopneumonia, atelectasis, verminous pneumonia, granuloma, necrosis and hemorrhage in variable percentages. As concerned with the liver, these microscopc lesions were coagulative necrosis, hepatic congestion, hydatid cysts, hemosiderin deposition, sinusoidal congestion, vacuolar degeneration and infiltration of inflammatory cells forming various rates. Uniform pathological observations and similar remarks of microscopical changes having identical description and morphological features were entirely demonstrated as explained in pathology references.
