Abstract
Background: Urinary tract infections are the second most common type of body infection. E. coli is the most common cause of urinary tract of infection both sex. This study was done with aim of surveying amount of susceptibility and resistance among strain of E. coli that had been isolated from those who refer to the private laboratories in Tabriz city. Materials and methods: In this cross-sectional study, 2850 E. coli collected from urinary tract infections of the patients. These strains were selected using laboratory standard methods and culture-specific. The antibiotic susceptibility testing was performed using Kirby-Bauer disk diffusion method. Results: The most of sensibility to imipenem were 90%, Nitrofurantoin 87.05%, Amoxicillin 85.27% the most amount for resistant to Ampicillin were 82.95%, Tetracycline 80.1%, Tobramycin 74.25%. Conclusion: This study showed increased resistance to different antibiotics in E. coli that is a serious warning to the treatment of infections caused by this bacterium in the region. Therefore, in order to prevent increased resistance to other antibiotics, it is essential to withhold prescriptions and unessential use of available antibiotics.
