Serovar-Specific Antimicrobial Resistance and Virulence Profiles of Salmonella enterica From Poultry in Bangladesh.

ABSTRACT: Salmonella enterica is a major foodborne pathogen that poses significant risks to public health and poultry production. This study aimed to investigate the distribution, serovar types, virulence genes, and antimicrobial resistance (AMR) profiles of S. enterica isolated from chickens in Bangladesh. A total of 250 samples from broiler (n = 100), layer (n = 100), and Sonali (n = 50) chickens were collected across four districts in Bangladesh and analyzed using polymerase chain reaction (PCR) and MALDI-TOF for identification and serotyping. The presence of virulence and AMR genes was assessed via PCR, while phenotypic resistance was determined using the disk diffusion method. In PCR, S. enterica was detected in 14.4% (36/250) of the samples, with significantly higher prevalence in layers compa
