ABSTRACT

In this study, totally, 295 cloacal swabs were collected from apparently healthy (195 swabs) and enteric (100 swabs) pet birds. After identification of Escherichia coli (E. coli) strains, to determining the E. coli producing extensive-spectrum beta-lactamase (ESBL) (EPE) strains, double disc synergy test was applied. TEM, CTX and SHV genes were detected in strains known as EPE phenotypically. The results showed that the detection rate of EPE strains in enteric birds is higher than apparently healthy birds (25.6 vs. 16.2%). The CTX gene was the highest ESBL gene. The SHV gene was not detected in any of E. coli strains. Furthermore, the ceftazidime and cefotaxime resistant E. coli strains were contained in the CTX gene. By considering the possibility of transmitting these genes along with other resistance genes to other bacteria, it can be stated that pet birds can be the source of transmission of resistance genes to human.
