Abstract

This research was conducted to investigate the extended spectrum beta-lactamase activity and multidrug resistance of Salmonella serovars isolated from chicken carcasses. For this purpose, 99 Salmonella isolates from 930 chicken carcasses were tested against 12 different antimicrobials. The resistance rates of Salmonella isolates to antimicrobials were as follows: 35.3% (35/99) to ampicillin, 33.3% (33/99) to tetracycline, 29.2% to amoxicillin-clavulanic acid, 18.1% (18/99) to nalidixic acid, 17.1% (17/99) to chloramphenicol, 16.1% (16/99) to aztreonam, 12.1% (12/99) to trimethoprim-sulfamethoxazole, 4% (4/99) to gentamicin, 1.0% (1/99) to ceftazidime. Of the isolates 46.4% (46/99) were found to be resistant to two or more antimicrobials as a multidrug resistance. Extended spectrum beta-lactamase activity was detected in 1.0% (1/99) of the isolates. Furthermore, S. Typhimurium 26.2% (28/99), S. Infantis 16.1% (16/99), S. Hadar 12.1% (10/99) and S. Branderburg 9.0% (9/99) were found to be the predominant serovars. In conclusion, antimicrobial resistance and also multidrug resistance rates of Salmonella isolates in this study, indicated that monitoring of antimicrobial resistance profiles is important for Salmonella infections to plan treatment strategies.
