Abstract:
Background and Aim : The second most common infection in the human body is a urinary tract infection with a different pattern of antibiotic resistance in each region. Escherichia coli is the most common cause of urinary tract infections in humans. The aim of this study was to evaluate the antibiotic resistance of Escherichia coli strains that were referred to the laboratory of Imam Khomeini Hospital in Shirvan in ۲۰۲۰.Methods : This descriptive study was conducted on ۴۳ isolates of E. coli. After identifying the bacteria by antibiotic sensitivity tests Biochemical and microbiological evaluation of isolates was performed by disk diffusion method according to CLSI guidelines.Results : Out of ۴۳ samples, ۷۹% of isolates belonged to women and ۲۱% to men. Antibiotic resistance was evaluated as follows: cotrimoxazole ۵۸%, ceftriaxone ۵۶%, ampicillin sulbactam ۵۴%, imipenem ۵۲%, ciprofloxacin ۳۵%, gentamicin ۱۹.۵%, nitrofurantoin ۵.۳%.Conclusion : According to the results of this study, the most common cause of urinary tract infection is Escherichia coli and it is recommended to use nitrofurantoin and gentamicin to treat urinary tract infections and avoid prescribing antibiotics cotrimoxazole and cefriaxone.
