Prevalência e susceptibilidade de bactérias isoladas em uroculturas de pacientes internados em hospital pediátrico público

Abstract

The objective of this study was to describe the characteristics and susceptibility of bacteria isolated in urine cultures of children admitted with suspected urinary tract infection (UTI) in a public pediatric hospital in Minas Gerais. This is an observational cross-sectional study, that data were collected from 2007 to 2017. The study population was children aged up to 13 years old, who remained hospitalized at the Hospital Infantil João Paulo II (HIJPII) with suspected UTI. Data from 264 patients were analyzed, most of them female and aged under one year old. Gram negative fermenting rods were isolated in 85.2% of the urine samples. The main uropathogens isolated were Escherichia coli, Klebisiela pneumoniae and Pseudomonas aeruginosa. The overall susceptibility to antimicrobials of uropathogens isolated was greater than 80%. The empirical antimicrobials that were effective after reviewing the susceptibility data were in descending order: aminoglycosides (96.9%), 3rd generation cephalosporin (92.2%), quinolones (92.0%) and carbapenems (90.9 %).First-generation cephalosporins were associated with lower success rates (78.2%).
