Objective To study the distribution of pathogens and resistance characteristics in urinary tract infections among children in our hospital and to provide basis for optimal selection of antibiotics by clinicians.
Methods The clinical data of 71 cases of urinary tract infections in hospitalized children were analyzed retrospectively. Kirby-Bauer Method was employed, and antibiotic resistance was determined according to NCCLS standard.
Results Gram-negative bacilli outweighed other pathogens. Escherichia coli accounted for 50.7%, Gram-positive bacteria accounted for 15.4%. Bacterial culture traced three major pathogens, namely, Escherichia coli, Klebsiella pneumoniae, and Staphylococci.
Conclusion Escherichia coli attributed to the majority of urinary tract infections in hospitalized children. There is a trend of increased proportion of Klebsiella and other enterobacteria. A substantial number of pathogens are resistant to antibiotics, some of which are multi-resistant strains. It is important to identify the pathogenic bacteria and select antibiotics according to drug susceptibility.
