Objective To research the distribution of common pathogenic bacteria and drug resistance of urinary tract infection in the hospital for providing reference of antimicrobial drugs for clinical reference. Methods Pathogenic bacteria isolated from the germiculture positive specimens of midstream urine and the antimicrobial susceptibility test results from Jan 2012 to Dec 2013 in our hospital were retrospective summarized. Results 479 strains pathogenic bacteria were isolated from 2463 urine samples totally. The positive rate was 17.3％, with 309 strains of gram-negative bacilli (64.51％),138 strains of gram-positive coccus(28.81％),32 strains of fungi(6.68％).The top 7 isolation of pathogens were strains of escherichia coli(36.53％),strains of klebsiella pneumoniae(12.73％),strains of enterococcus faecalis D group(12.32％),strains of enterococcus faecium D group(10.23％),strains of fungi(6.68％),strains of pseudomonas aeruginosa(5.22％),strains of staphylococcus epidermidis(3.13％).125 strains of klebsiella pneumoniae produced ESBL were detected out with the rates of up to 71.42%. The strains of gram-negative bacteria were based on enterococcus faecalis (D group),yet staphylococcus aureus methicillin resistant strains accounted for 27.27%. Conclusion Escherichia coli is the main pathogenic bacteria of child urinary tract infection and the multidrug resistance of the pathogenic bacteria is in a very serious situation. And gram-positive cocci is going to be increasing. It is necessary to make clear pathogens and drug sensitivity results, which is important to guide clinic make use of antibacterial agents exactly to cure infection of urinary system in children.
