Abstract:
Objective:To investigate the distribution and drug resistance of pathogens in urinary tract infection in children.Methods:The clinical data of 108 cases of urinary tract infections with positive urinary culture from January 2018 to December 2018 in our hospital were analyzed retrospectively.The patients were divided into simple urinary tract infection group( n=29) and complex urinary tract infection group( n=79). Antibiotic resistance in each group was compared. Results:Gram-negative bacilli were found in 90 cases(77.59%, 90/116). Gram-positive cocci were found in 26 cases(22.41%, 26/116). Escherichia coli, Klebsiella pneumoniae and Enterococcus faecium were the main pathogens.Gram-negative bacilli had the lowest resistance rate to amikacin, imipenem and piperacillin/tazobactam(about 10%). The resistance rate of Gram-negative bacilli to furantoin and quinolones was about 20%, while 30% to 40% to the third and fourth generation cephalosporins and their enzymatic preparations.No Gram-positive cocci was found to be resistant to vancomycin and linezolid.The resistance rate of Gram-positive bacteria to streptomycin and furantoin was 0-20%.There was no significant difference in resistance rate of Gram-negative bacteria to common antibiotics between simple urinary tract infection group and complex urinary tract infection group( P>0.05). Conclusion:Gram-negative bacteria are the main pathogens of urinary tract infections.With the change of drug resistance of pathogens, it may be necessary to change the empirical treatment of urinary tract infection.Furantor can be used as a recommendation for the empirical treatment of mild infection.In the past, there may be underestimate of drug resistance of simple urinary tract infection, and further research is needed.
