Salmonella spp in chicken meat provided from İstanbul investigation of prevalence, serotyping and antibiotic sensitivity in strains

Salmonella is one of the most important pathogenic microorganisms causing foodborne diseases and epidemics in many regions of the world. The presence of Salmonella serotypes and the fact that these serotypes have developed resistance to various antibiotics pose significant risks in the treatment of human and animal diseases. The aim of this study was to determine the presence, serotyping and antibiotic susceptibility of Salmonella spp. in chicken meat obtained from different markets and butchers operating in the European and Asian sides of Istanbul. In this context, a total of 210 raw chicken meat samples were analyzed by the classical culture method according to ISO 6579-1. A total of 13 Salmonella strains were isolated from 12 (5.7%) chicken meat samples. In addition, the strains isolated by the classical method were confirmed and serotyped by molecular method. In this context, a total of 6 S. Infantis strains isolated from the European side, 1 from drumstick and 5 from wing origin, 1 S. Virshow strain from wing origin, 4 of 5 S. Infantis strains isolated from the Asian side, 4 from wing and 1 from cutlet origin and 1 S. Enteritidis strain from tenderloin origin. In the study, antibiotic susceptibility was tested by disk diffusion method and 13 Salmonella serotypes [Infantis (11) and Enteritidis and Virshow] were tested for susceptibility to cefazolin, pefloxacin, azithromycin, azithromycin, susceptibility to trimethoprim/sulfamethaxozole, gentamicin, kanamycin, chloramphenicol, tetracycline, ampicillin, cefotaxime, amoxicillin-clavulanic acid and cefazolin antibiotics. All isolates were resistant to cefazolin, pefloxacin, azithromine, tetracycline and all isolates were susceptible to ampicillin and gentamicin. In conclusion, in addition to raising public awareness to control the problem of antimicrobial resistance, which is of global importance today, the role and collective efforts of physicians, veterinarians and other professionals are of great importance to protect public health in line with the concept of "One Medicine One Health"
