Antimicrobial resistance of Escherichiacoli and Salmonella isolated from retail broiler chicken carcasses in Zambia

Antimicrobial resistance (AMR) of foodborne pathogens is public health concern, especially in developing countries such as Zambia. This study was undertaken to determine the antimicrobial profiles Escherichia coli (E. coli) and Salmonella isolated from retail broiler chicken carcasses purchased open markets supermarkets A total 189 E. five isolates were isolated. Identification confirmation done using Analytical Profile Index (API 20E) (Biomerieux®) 16S rRNA sequencing. susceptibility tests (AST) performed Kirby Bauer disk diffusion technique a panel 9 antibiotics. WHONET 2018 software used analyze AST results. The mostly resistant tetracycline (79.4%), ampicillin (51.9%), trimethoprim/sulfamethoxazole (49.7%). Two at least one antibiotic. has demonstrated presence AMR on supermarkets, which concern.
