Abstract :Salmonella spp. infection is considered a crucial trouble of the poultry industry in Bangladesh. Hence, this study was aimed to estimate the seroprevalence of Salmonella spp. in poultry along with biosecurity practices that are associated with this Salmonella spp. infection. The study was conducted during the period from January to September, 2021 in Mymensingh and Gazipur district of Bangladesh. A total of 314 samples were considered to determine the seroprevalence. Seroprevalence was determined by performing the rapid serum plate agglutination test. The result revealed that the overall Salmonella spp. seroprevalence was 47.77% in the study area. The higher seroprevalence was in Mymensingh insert ignore into journalissuearticles values(51.59%); than Gazipur insert ignore into journalissuearticles values(45.21%); without significant insert ignore into journalissuearticles values(p>0.05); difference. The highest seroprevalence was in broiler insert ignore into journalissuearticles values(51.33%); where in layer and sonali was 32.67% and 16% respectively. Seroprevalence was significantly insert ignore into journalissuearticles values(p<0.05); higher in summer for layer insert ignore into journalissuearticles values(56.45%);, broiler insert ignore into journalissuearticles values(60.64%); and sonali insert ignore into journalissuearticles values(51.22%); than the winter seasons. In layer farms, the flock size of >2000 to <2500 had significantly insert ignore into journalissuearticles values(p<0.05); higher insert ignore into journalissuearticles values(71.43%); seroprevalence. In broiler farms, 15 to 30 days old birds had significantly insert ignore into journalissuearticles values(p<0.01); higher insert ignore into journalissuearticles values(77.05%); seroprevalence than other age. Among the different categorical level of biosecurity practices, the poultry farms that used surface water insert ignore into journalissuearticles values(OR=0.182, 95% CI=0.106-0.314);; disinfectant regularly insert ignore into journalissuearticles values(OR=0.296, 95% CI=0.171-0.511);; having density of 8-10 birds/meter2 insert ignore into journalissuearticles values(OR=0.379, 95% CI=0.219-0.654);; cleaned waterer and feeder regularly insert ignore into journalissuearticles values(OR=0.503, 95% CI=0.294-0.862);; and having visitor restriction insert ignore into journalissuearticles values(OR=0.375, 95% CI=0.219-0.643); showed lower tendency insert ignore into journalissuearticles values(p<0.001); to seroprevalence. In brief, Strict farm hygienic practice and biosecurity measures are significantly linked to decrease the Salmonella spp. seroprevalence.
