The study was undertaken to investigate some common bacterial diseases in commercial poultry farm. A total of 100 sick and dead chickens (67 broilers, 26 layers and 7 sonali) were collected from different poultry farms which were subjected to postmortem examination for tentative diagnosis. After the post-mortem examination, out of 100 collected dead chickens, bacterial diseases were confirmed 58 %. Among them 52 % of the chickens were diagnosed tentatively to be the case of colibacillosis, 4 % salmonellosis, and 2 % of fowl cholera. In post-mortem examination, some pathological lesions like: omphalitis, fibrinopurulent fluid accumulation in peritoneal cavity, air sacculitis, pericarditis and perihepatitis, extreme congestion and septicemia in intestine for colibacillosis infection; unabsorbed yolk mass, bronze discoloration and friable liver, hemorrhages in spleen, misshaped ova for salmonellosis as well as swollen and hardening of comb, congestion of skin, multiple pin point pale color necrotic lesion on liver, pin point hemorrhage on fat muscle of heart were observed for fowl cholera infection. Hence, this study will definitely help to perceive the prevalence of common bacterial diseases like colibacillosis, salmonellosis and fowl cholera infection in commercial poultry farm. ER -
