Prevalence and antimicrobial susceptibility profiles of nontyphoidal Salmonella isolated from chickens in Rajshahi, Bangladesh

Abstract

Salmonellosis in poultry is an important disease that seriously impedes the development of the poultry industry. The increased resistance to antimicrobials against Salmonella has been a major public health concern worldwide. We conducted a study from January to June 2016 in and around the Rajshahi district of Bangladesh on the commercial chicken to isolate, identify and characterize poultryspecific Salmonella, to assess the potential risk factors and to determine the antimicrobial resistance pattern of the isolates. The overall prevalence of Salmonella enterica was 41% (49/120) [95% CI: 31.95%– 50.17%] with 41.7% in broiler chicken (25/60) [95% CI: 29.06%– 55.12%] and 40% in layer chicken
