Abstract:

Aim: Urinary tract infeetions (UTI) are common in pediatric age group. To select the proper ampirical treatment, it is essential to know the prevelance of uropathogens and local antibiotic resistance profile.The aim of our study was to investigate the bacterial profile and the pattern of antibiotic resistance for UTI in our hospital and determine the impact of these results on the ampirical treatment. Methods: In this study, culture and antibiogram resul ts of 10850 urine samples obtained betvueen July 1, 2003 and July 31, 2004 were evaluated retrospectively to determine bacterial profile and antibiotic resistance pattern of pediatric urinary tract infections in our hospital. Results: 2793 urine samples were culture positive (25.7%). 76.9% of the positive cultures were found Gram-negative bacilli and 20.9% as Gram-positive cocci. E.coli was the most freguently isolated causative agent (51.5%). Methiciline sensitiue S. Aureus (MSSA) was most frequently isolated Gram-positiue microorganism (8.7%). Among ali of the microorganisms, the lowest resistance rates were obserued to carbapenems. Conclusion: In our clinic, the most common pathogens of UTI are Gram-negative bacilli, out of them E.coli was the most frequently isolated causative agent. Antibitic resistance rates are high except carbapenems.
