| dc.description.abstract | The present study aimed to isolate Escherichia coli from chickens with colibacillosis, to detect the presence of important serotypes (O1, O2, O18, O78) and to examine antibiotic susceptibility profiles and resistance genes in antibiotic resistant isolates in Turkey. A total of 150 E. coli isolates collected from internal organs of broilers with colibacillosis were used in the study. Antibiotic resistance status of these isolates to 12 antimicrobial agents that belong to 7 antimicrobial families was examined by the disk diffusion method. The most important 23 resistance genes in antibiotic-resistant isolates and important APEC (Avian pathogenic E. coli) serotypes were investigated by polymerase chain reaction (PCR). While 6.7% of the isolates were found to be susceptible to all antimicrobials, 66.7% were multidrug resistant. It was determined that 150 isolates of E. coli were resistant at a rate of 73.3%, 68.7%, 63.4%, and 60.7% to amoxicillin/ampicillin, tetracycline, enrofloxacin, and trimethoprim/sulfamethoxazole, respectively. The blaTEM, blaCMY, blaSHV, blaCTX, blaOXA, tetA, tetB, qnrA, drfA1, drfA7,17 and sulII antibiotic resistance genes were detected. It was determined that 18.0% of isolates were O78, 10.0% were O2, 2.7% were O1, and 2.0% were O18. It was concluded that further epidemiological studies should be designed to investigate the virulence properties and clonal groups of APEC. This study was the first research of serotypes and antibiotic resistance genes of APEC isolates in Turkey using molecular methods. © 2019, Verlag Eugen Ulmer. All rights reserved. | |
