Abstract
Purpose: The aim of the study was to determine the aminoglycosides resistance of Escherichia coli (E. coli) strains isolated from acute uncomplicated cystitis.

Materials and Methods: All 219 female patients who presented with symptoms of acute cystitis by E. coli infection were included in this study. We used gentamicin, tobramycin, and amikacin for detecting the resistance to aminoglycosides. The prevalence of gentamicin, tobramycin, and amikacin resistance of E. coli was 25.1%, 24%, and 0.4%, respectively.

Results: The resistant isolates to tobramycin or gentamicin definitively showed an associated resistance to other antibiotics such as ciprofloxacin and trimethoprin-sulfamethoxazole, while the resistance to amikacin was not. In addition, 3 aminoglycosides resistant E. coli isolates did not associated with the history of recurrent cystitis.

Conclusions: We recommend the clinical use of amikacin for the ciprofloxacin or trimethoprim- sulfamethoxazole
resistant E. coli isolates from urinary tract infection, instead of gentamicin or tobramycin.
