Abstract: Objective To investigate the changes of pathogens distribution and antimicrobial resistance in children with urinary tract infection (UTI) in 10 years. Methods The results of urine culture and drug sensitivity in children with UTI from January 2001 to December 2003, and from January 2011 to December 2013 were retrospectively analyzed．Results In recent 10 years, there was no obvious change in the ratio of gram-negative bacteria to gram-positive bacteria. Escherichia coli was still the main bacteria causing UTI in children. The detection rate of enterococcus was significantly increased from 18.3% in 2011-2013 to 7.5% in 2001-2003 (P<0.05) and it had become the second pathogenic bacteria. The isolation rate of ESBLs producing strains was significantly higher in 2011-2013 than in 2001-2003 (P<0.05). The rate of Escherichia coli sensitive to imipenem remained at 100% and it is also sensitive to enzyme inhibitors antibiotics and nitrofuranto. Sensitivities to antibiotics were changed in different species of enterococcus. Conclusions The distribution of pathogens and antimicrobial resistance in children with UTI are constantly changing. The clinician should pay close attention to changes of epidemiology in the region and hospital and rational use of antimicrobial drugs.
