Objective: the aim of this study was determination of antibiotic resistance profile, investigation of class I and II integrons among Escherichia coli (E. coli) isolates from urinary tract infections. This study was conducted for the investigation of the prevalence of class I and II Integrons among E. coli Isolates from urinary tract infections. Materials and Methods: A total of 100 E. coli clinical isolates were collected from urinary tract infections in Borujerd city, Iran, from… to …. All the isolates were identified with standard laboratory procedures as described everywhere. The antibiotic susceptibility profile was conducted against adopted antibiotic disks following CLSI 2016 guidelines. All the isolates were enrolled in the PCR technique for the presence of class I and II integrons. Results: the highest resistance was against amoxicillin (72%), ciprofloxacin (69%), nalidixic acid (55%) and tetracycline (51%). The prevalence of class I and II integrons was 31% and 21%, respectively. A significant relation was observed between resistance to trimethoprim-sulfamethoxazole (p<0.001), nalidixic acid (p<0.01) and tetracycline (p<0.005) with the presence of class I integron. The rate of class I integron in the E. coli isolates was high, possibly playing a role in the spread of multidrug resistant isolates. Conclusion: considering the significant relation observed between the presence of class I integron among multidrug-resistant isolates, establishment implementation of proper procedures to control and suitable treatment strategies in hospitals seems essential for the prevention of more spread of these isolates.
