The study was designed to evaluate the isolation and identification of causative bacteria from caprine pneumonic lungs, antibiotics sensitivity test with isolated bacteria, gross and histopathological changes to determine the types of pneumonia. A total of 210 Black Bengal goat carcasses were subjected to gross examination and infected with pneumonia were collected for bacteriological and histopathologica study. Pneumonia was detected in 40 carcasses. Bacteriological examinations revealed the

... esence of ovine pathogens, such as Staphylococcus spp. (35%), Escherichia coli (25%), Pasteurella spp. (20%), Streptococcus spp. (15%), and Klebsiella spp. (5%). The antibiogram study indicated that the most effective antimicrobial agents against all the tested isolates were ciprofloxacin; ceftriaxone; and oxytetracycline; could be the choice of antibiotics for the treatment of pneumonia in Black Bengal goats. The gross lesions were recorded as hemorrhage (25%), congestion (20%), hemorrhage and congestion (30%), emphysema (15%), and hepatization (10%) of lungs. Based on the histopathological study, 30% of affected carcasses were bronchopneumonia, 25% with fibrinous bronchopneumonia, 20% with hemorrhagic pneumonia, 15% with interstitial pneumonia, and 10% with purulent bronchopneumonia. Both gross and histopathological lesions of above diseases were enunciated. However, other etiology may also have a considerable effect on the occurrence of pneumonia in Black Bengal goat of Bangladesh.
