Drug resistance and distribution of pathogenic bacteria in urinary tract infection

Objective To investigate the distribution and drug resistance of pathogenic bacteria in urinary tract infection and offer scientific basis for reasonable usage of antibiotics.Method All 655 strains of pathogenic bacteria isolated from urinary tract infection specimens were identified and drug susceptibility tests were performed by using K-B methods or ATB FUNGUS 3.Results Among the pathogenic bacteria isolated,the top five ones were Escherichia coli(37.9%),Candida(18.0%),Enterococci(13.1%),Klebsiella pneumoniae(6.6%),and Pseudomonas aeruginosa(6.3%).The pathogens showed varying degrees of resistance to various antimicrobial agents;the resistance rates of Klebsiella pneumoniae and Pseudomonas aeruginosa to Imipenem and Meropenem were 14.3%-26.8%.Conclusion In Shenzhen People′s Hospital,the main pathogens of urinary tract infection are Escherichia coli,Candida,and Enterococci.Drug resistance has been emerging in pathogenic bacteria in urinary tract infections.We should take better monitor and control of them.
