      abstract = {The present study was conducted to determine the  seroprevalence of Salmonella infections in poultry. This  study covered cultural prevalence with isolation and  identification of the causal agent and pathological lesions  in different organs produced by Salmonella in layer farms  of Mymensingh district during July-December 2007. The  materials were blood samples, liver and cloacal swabs from  live and dead birds. The used methods were whole blood  agglutination test by commercially available Salmonella  antigen kit, culture in different media, Gram’s staining,  motility test, basic 5 sugar fermentation test and  histopathology. The overall seroprevalence was 45.9% in  live bird and the rate of seroprevalence decreased with  advancement of age of birds. The cultural prevalence in  seropositive group was 71% and in seronegative group was  59%. In dead bird, the cultural prevalence in liver was 64%  and from cloaca 57%. A total 160 isolates were  characterized, among them 64.2% were Salmonella Pullorum,  22.3% were Salmonella Gallinarum and 13.5% were Paratyphoid  group of Salmonellae. Pathologically friable, bronze color  liver with focal necrosis, various grades of enteritis, and  hemorrhagic and congested egg follicles with stalk  formation were found. Microscopically, focal necrosis and  degeneration with leukocytic infiltration in liver,  inflammatory cells in the mucosa and submucosa of intestine  were found. In egg follicles, congestion and hemorrhages  with leukocytic infiltration were found. The isolated  Salmonella organisms may be used for further research such  as serotyping, vaccine production and antibiotic  sensitivity test.},
