摘要：

Tetracycline- resistant bacteria have emerged due to the selective pressure of antimicrobial use. The aim of this study was to determine the prevalence of oxytetracycline resistance of Escherichia coli from pigeon faecal samples. All strains were examined for the presence and types of oxytetracycline resistance determinants using disc diffusion and polymerase chain reaction methods. Of 50 faecal E. coli. isolates, 30 (60%) were resistant to oxytetracycline. Polymerase chain reaction analyses indicated that the most common genes found in these isolates were tetB (43.3%) and tetA (30%). Only 10% and 3.3% of the isolates contained otrA and otrB, respectively. In conclusion, our findings suggest that oxytetracycline-resistant strains of E. coli are disseminated in pigeons.
