Constituent ratio and antimicrobial resistance of pathogenic bacteria causing urinary tract infections in children

OBJECTIVE To investigate the constituent ratio and antimicrobial resistance of pathogenic bacteria causing urinary tract infections in children and provide the reference for clinically reasonable use of antibiotics.METHODS The strains isolated from urine specimens from Jan.2008 to Dec.2010 were recruited in this study.The positive results of urine culture were statistically analyzed.RESULTS Among 115 isolates,the majority was Escherichia coli and Enterococci which accounted for 40.0% and 17.4%,respectively.Except for 100.0% susptibility rate of imipenem and meropenem to gram-negative bacilli and of vancomycin and teicomycin to gram-positive cococci,pathogenic bacteria were resistant to the most commonly used antibiotics in varying degree.CONCLUSION The constituent ratio of pathogenic bacteria from children was similar to adults.The antimicrobial resistance was rising.We should take effective measures to control the increasing tendency of antimicrobial resistance.
