Prevalence of some common bacterial diseases in commercial poultry farm

Abstract

Bacterial disease of poultry is one of the major constraints to the expansion of poultry industry. 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.

Prevalence and Antimicrobial Resistance Profile of E. coli and Salmonella spp. from Liver and Heart of Chickens

“…The study was conducted from February to July 2018 at the Department of Pathology and Parasitology, Faculty of Veterinary Medicine, Chattogram Veterinary and Animal Sciences University (CVASU), Chattogram. Liver and heart samples were used that we previously collected (Halder et al, 2021) through postmortem of a total of 100 dead and sick chickens of various farms of Chattogram, Bangladesh.…”

“…To know the prevalence of colibacillosis and salmonellosis on the basis of different factors, we collected related information by using our previously designed wellstructured questionnaire (Halder et al, 2021).…”
