Investigation of antibiotic susceptibility of Salmonella spp. strains’ isolated from raw chicken meat

The aim of this study was to investigate the antibiotic susceptibility, resistance status and to determine the ESBL properties with Vitek in Salmonella spp. strains, which was isolated and identified from raw chicken meats. In this study, chicken meats were analyzed for Salmonella spp. isolation. As a result of isolation and identification, a total of 35 Salmonella spp. isolated. As a result of the antibiotic susceptibilities tests, according to the results of Vitek 2 Compact AST GN 38, all isolates were found to be resistant to amikacin, cephalexin, tobramycin, gentamycin and enrofloxacin. 29 (82.85%) isolates were found to be resistant to tetracycline and nitrofurantoin. 20 (57.15%) and 21 (60%) isolates were found to be resistant to ampicillin and piperacillin respectively. In addition, extended spectrum beta-lactamase was detected in 4 isolates. According to the results of disc diffusion method, all isolates were found to be resistant against erythromycin. 34 (97.14%) of all isolates were found to be resistant against sulfonamide compounds, 28 isolates (80%) were found to be resistant against ampicillin sulbactam and sulfamethoxazole/trimethoprim, 26 isolates (74.28%) were found to be resistant against neomycin, 29 (82.85%) isolates were found to be resistant against oxytetracycline and tetracycline, 31 (88.57%), 17 (48.57%), 10 (28.57%), 6 (17.14%) were found to be resistant against ofloxacin, florfenicol, amoxicillin, chloramphenicol respectively. 24 (68.57%) and 6 (17.14%) isolates were found to be intermediate (I-drug increased contact sensitive) and resistant to ciprofloxacin, respectively. In view of these results, it was thought that, in terms of public health, it could cause infection in people consuming contaminated foods with multiple antibiotic resistance strains, antibiotics could not be effected due to multiple antibiotic resistance and increase in the number of resistant strains. Finally, it was thought that the studies on antibiotic resistance could be beneficial in terms of epidemiolog
