Prevalência e sensibilidade de microrganismos isolados em uroculturas no Espirito Santo, BrasilPrevalence and sensitivity of microrganisms in isolated urocultures in Espírito Santo, Brazil ABSTRACT The urinary tract infection (UTI) is one of the most frequent bacterial infections occurring in humans, and it is considered the second most frequent infection in the world. This work aims to identify and describe the prevalence and sensitivity of microorganisms isolated from urine cultures. A cross-sectional study was done involving the retrospective analysis of existing data in urine cultures logbooks performed between December of 2012 and April of 2013, in private laboratories of the south region of Espirito Santo. Logs from 413 positive urine cultures and their antibiotic susceptibility results were analyzed to obtain the prevalence of microorganisms and their sensitivity profiles. The analyzed data show that 87,9% belonged to female patients; the most common microorganism was Escherichia coli, detected in 71,0% of urine cultures. Regarding the tested antibiotics, ampicillin was the less active, inhibiting only 42,3% of organisms growth, followed by sulfamethoxazoletrimethoprim (60,0%), cephalothin (65,1%) and cefazolin (69,7%). The frequency of the isolated uropathogenic organisms and their profile of sensitivity and resistance varied according to the region and the population studied.
