Analysis of pathogenic characteristics and drug resistance of urine culture in children

Abstract

Objective To investigate the distribution of pathogenic bacteria characteristics and antimicrobial susceptibility results in children with positive urine culture specimen in order to provide some references for the clinical rational use of antimicrobial agents. Methods The pathogenic data of children in our hospital in 2017 with positive urine culture specimen were collected and statistical analyzed. Results A total of 364 strains of 23 pathogens have been isolated, which the Escherichia coli was dominant, accounting for 41.21%(150 strains). followed by Enterococcus faecium(18.41%), Klebsiella pneumoniae (14.29%) and Enterococcus faecalis (7.15%). Different pathogenic bacterias have varying degrees of drug resistance to commonly used antibiotics.The drug resistance rates of Escherichia coli to ampicillin, piperacillin, cefmenorr and cefazolin were 88.36%, 85.71%, 81.58% and 81.16%.The drug resistance rates of Enterococcus faecium to ampicillin, clindamycin and penicillin G were 100%; the drug resistance rates of Klebsiella pneumoniae to ampicillin, tetracycline, cefazolin and cefuroxime axetil were 96.08%, 92.31%, 82.98% and 80%; All Enterococcus faecalis detected were sensitive to quinupristin/dalfopristin and clindamycin. Conclusion Escherichia coli, Enterococcus faecium, Klebsiella pneumoniae and Enterococcus faecalis are common pathogens in positive urine culture of children.Clinicians should use antibiotics reasonably according to the pathogenic characteristics.
