Isolation and molecular characterization of multidrug-resistant *Escherichia coli* from chicken meat

M. M. Rahman, A. Husna, et al.

This groundbreaking study conducted by a team of researchers from Sylhet Agricultural University and other institutions reveals a striking prevalence of multidrug-resistant *Escherichia coli* in raw chicken meat in Sylhet, Bangladesh. The findings underscore urgent concerns about antibiotic resistance in poultry and the need for responsible antimicrobial practices.

Abstract
This study investigated the isolation and characterization of multidrug-resistant (MDR) *Escherichia coli* from raw chicken meat in Sylhet, Bangladesh. 600 chicken meat swabs were collected and analyzed, revealing a high prevalence of *E. coli* (63.5%). Antimicrobial susceptibility testing showed resistance to multiple antibiotics. PCR identified various antibiotic resistance genes (ARGs), with *tetA* (tetracycline resistance) being the most prevalent. A significant number of isolates were MDR, harboring multiple ARGs. ESBL and AmpC beta-lactamase genes were also detected. Significant correlations were found between resistant phenotypes and genotypes. The findings highlight the concerning prevalence of antibiotic resistance in chicken meat and underscore the need for prudent antimicrobial use in poultry farming.
