This study aims to evaluate the presence of ESBL and pAmpC producing Salmonella spp. and Escherichia coli O157:H7 in bovine carcasses and assess their antibiotic resistance profiles.
Examined 300 bovine carcasses for Salmonella spp. and E. coli O157:H7 using culture-based isolation methods.
Confirmed isolates by molecular methods and performed antimicrobial susceptibility testing per EUCAST guidelines.
Determined ESBL and pAmpC production phenotypically and characterized by molecular methods.
Recovered 25 Salmonella spp. (32% S. Enteritidis, 68% S. Typhimurium) and 20 E. coli O157:H7 isolates.
Detected stx2 as the most frequent virulence gene with 31 phenotypically ESBL-positive isolates, 29 carrying ESBL genes.
Identified multidrug resistance in 34 (75.6%) isolates, with all isolates resistant to pefloxacin.
