Prevalence and Antimicrobial Resistance Patterns of Escherichia coli Isolated From Broiler Chickens in Sylhet District of Bangladesh.

ABSTRACT: The emergence of antimicrobial resistance (AMR) Escherichia coli in poultry farming is a growing global public health concern, particularly in Bangladesh, where the use of antibiotics remains largely unregulated. This study aimed to determine the prevalence and AMR patterns of E. coli isolated from broiler chickens in Sylhet district of Bangladesh and to investigate the network of coexisting resistance traits among the isolates. A total of 130 samples (44 cloacal, 46 faecal, 21 liver and 19 intestinal) were collected from live and dead broiler chickens in the Sylhet district of Bangladesh from July 2020 to June 2021. E. coli was detected in 77.7% of samples by standard cultural and biochemical tests, with 65.4% confirmed by polymerase chain reaction (PCR) targeting the malB gene. Antibioti
