dc.description.abstractSalmonellosis is a critical challenge in commercial poultry farming. This study aimed to calculate\rseroprevalence, identify Salmonella spp., and its pathological investigation from January to\rDecember 2019. One hundred fifty (150) serum samples and fifty (50) cloacal swabs from\rapparently ill and healthy birds were collected in this study. Seroprevalence was observed by serum\rplate agglutination (SPA) tests. The tentative diagnosis of salmonellosis was made based on history,\rclinical signs and bacteriological studies. Salmonella spp. was further confirmed using an\rautomated microbiological method (VITEK®2). Post mortem examination was done in apparently\rsick birds, and gross and microscopic pathological lesions were investigated and recorded in a\rdatasheet. The overall seroprevalence of salmonellosis was 42.67% in commercial chickens. Age\rwise prevalence of avian salmonellosis showed significantly highest infection rate in adult layers\r(? 45 days old) 65.31%, then 40.74%up to 45 days. In case of broiler, the prevalence rate in 0-10\rdays, 11-20 days, and 21-35 days were 13.63%, 44.12%, and 16.67%, respectively. Seasonal\rinfluence showed significantly highest proportionate prevalence of salmonellosis during summer\r66.15%in comparison to winter 25.00% and rainy 24.44% seasons respectively. In bacteriological\rstudy, 12 samples were positive for Salmonellae among 50 cloacal samples. Out of 12 positive\rsamples 5 samples were selected for the automated microbiology system VITEK® 2, and only two\rsamples were confirmed as Salmonella gallinarum. Gross pathology of representative organs\rrevealed bronze-colored enlarged liver, hemorrhages in the spleen and lungs, and hemorrhages in\rthe ovary with stalk development. Microscopically, multifocal nodule formation and infiltration of\rinflammatory cells in the liver parenchyma and marked congestion with inflammatory cells in the\rspleen, hemorrhage and congestion in the lungs and intestine.
