Distribution and Drug Resistance of Pathogenic Bacteria of Urinary Tract Infection in Children / 实用儿科临床杂志

ABSTRACT

Objective To explore the pathogenic bacteria′s distribution and their drug resistance of urinary tract infection in children.Methods A total of 555 pathogen strains in urinary tract infection for children from inpatients and outpatients from Jan.2005 to Dec 2006 were identified and the drug resistance test was preformed.Results In the 555 strains of bacteria,80.7% were Gram-negative,17.7%were Gram-positive and 1.6%were fungi.Most of Gram-negative bacteria were E.coli,among 300 strains of identified Escherichia,69.3% of them(208 strains) produced extended speetrum ? lactamases(ESBLs);among 41 strains of identified Klebsiella pneumoniae,78.1% of them(32 strains) produced ESBLs.Most of Gram-positive bacteria were Enterococcus,there were 70 strains(12.6%),sensitivity rates of nitrofurantion and vancomycin were 100%.Conclusion Gram-negative is the main infection bacterium in urinary tract infection for children and the most of them are very serious drug resistant.The clinicians should pay more attentions to idstream urin bacteriology culture and choose the suitable antibiotic according to the results of antibiotic susceptibility tests.
