Aim:

Bacterial infections of the urinary tract in children are one of the most common diseases in outpatient health care. Their proper and effective management requires updating local knowledge of the types of virulent microorganisms responsible for pediatric urinary tract infections and information of their resistance patterns. The aim of the research was to o determined the frequency and type of uropathogenic microorganisms in children.

Method:

A cross-sectional study was conducted among 219 outpatients under 18 years of age with suspected urinary tract infections from Stara Zagora region in the time period January - June 2023. It was applied the microbiological procedures - urine sample culture and antibiotic sensitivity test of the isolated uropathogens.

Results:

51.11% of outpatients with a positive urine culture had a urinary tract infection caused by strains of the Gram-negative bacteria - E. coli that showed increasing levels of resistance to Trimethoprim sulfometaxazole. Fluoroquinolones are the only class of antibiotics to which relatively high susceptibility rates of all Enterobacteriaceae isolates have been calculated. 100% resistance levels to most of the routinely prescribed antibiotics have been measured in isolates of the dominant Gram-positive microorganism- Enterococcus faecalis.

Conclusions:

Both increasing and alarmingly high rates of antibiotic resistance among gram-positive and gram-negative bacteria that cause pediatric urinary tract infections have been reported. The presented results should not be ignored by physicians when choosing and applying an antibiotic therapeutic regimen.
