The present study was conducted to evaluate the bronchopneumonia associated with the bacterial aetiology in sheep from various slaughter houses, postmortems and meat sales outlets of Jaipur Division, Rajasthan. A total of 436 entire lung samples were examined, out of which 102 lungs (23.39%) found with gross lesions were used for the study. For bacteriological isolation, swabs were collected at the site of the lesion from within tissue parenchyma under sterile conditions. Out of 102 sheep lungs with clear gross lesions 79 (77.45%) lungs were found to harbour bacteria. The predominant species were Escherichia coli, Streptococcus spp, Staphylococcus spp, Pseudomonas spp, Klebsiella spp and Enterobacter spp. These bacteria were isolated and phenotypically characterized using standard techniques. For pathomorphological evaluation, only those lungs (79) that were found infected with bacteria were considered. The gross pathology and histopathological findings were studied and lesions were grouped as 09 (11.39%) lungs with abnormalities of inflation (including emphysema and atelectasis), 02 (2.53%) with circulatory disturbances (including congestion, haemorrhage and oedema), 67 (84.81%) with inflammatory conditions (including suppurative or fibrinous bronchopneumonia, interstitial pneumonia and pleuritis) and 01 (1.27%) with parasitic hydatidosis. It is concluded that the pneumonia (83.54%) is the major lung affection in sheep from Jaipur Division and the Streptococcus spp and Escherichia coli were the most common bacteria causing pneumopathies.
