Trends in Positive Urine Culture Rates and Antimicrobial Resistance in Non-Hospitalized Children from Western Romania: A Retrospective Observational Study.

A higher number of positive urinary tract infections samples was observed in females when compared to males and in children aged 6-12 and 12 to 18 years when compared to those aged 1-5 years.

The antibiotic susceptibility testing of E. coli isolates revealed high sensitivity to most tested antibacterials.

Near-complete susceptibility was observed for fosfomycin (99.71%) and nitrofurantoin (96.01%), while high susceptibility rates were also observed for ciprofloxacin (85.43%) and amoxicillin-clavulanic acid (75.05%).

In contrast, high resistance was found for ampicillin (62.28% resistant) and trimethoprim-sulfamethoxazole (36.53% resistant).
