ABSTRACT

Antibiotic resistance has been rapidly increasing all over the world. Presence of antibiotic resistant bacteria in food producing animals is considered an important transmission source for both direct and indirect transfer of those bacteria to human. For this reason, 45 cloacal samples comprising from 23 Japanase quails and 22 chickens were analyzed by conventional and molecular methods for E. coli isolation in this study. Subsequently, antimicrobial susceptibility profiles of E. coli isolates (n=71) were determined against thirteen agents; amoxicillin-clavulanic acid, piperacillin-tazobactam, ceftazidime, cefotaxime, ceftriaxone, cefpodoxime, aztreonam, ciprofloxacin, amikacin, ertapenem, imipenem, meropenem, trimethoprim-sulfamethoxazole by disk diffusion method. Double-disk synergy test (DDST) was also performed for detection of Extended Spectrum β-Lactamase (ESBL)-producing organisms. As a result, majority of poultry isolates was susceptible to most of the tested antibiotics and highest resistance rates were detected for ciprofloxacin (2.8%) followed by ertapenem, imipenem, meropenem with equal resistance rates of 1.4% with CLSI interpretative criteria. However, analyzing of the same data according to EUCAST interpretative criteria resulted in higher number of resistant isolates (n=16). In this case, isolates showed resistance to amoxicillin-clavulanic acid (7%), cefpodoxime (5.6%), ciprofloxacin (5.6%), ertapenem (2.8%) and aztreonam (1.4%). No ESBL-producing organism was detected among isolates. This is the first report on ertapenem resistant bacteria from various poultry sources in Turkey. Therefore, it is important to perform surveillance on the antibiotic resistant bacteria in healthy livestock animals for predicting their risk status to society.
