Analysis of the Isolation and Drug Sensitivity of Common Pathogenic Bacteria in Urinary Tract Infection

[Objective]To understand the distribution and drug resistance of pathogenic bacteria in urinary tract infection and provide reliable basis for diagnosis and treatment.[Methods]147 strains of pathogenic bacteria isolated and cultured from the urine of the inpatients and outpatients in the General Hospital of Ji'nan Military Region from 1 June 2007 to 31 May 2008 were identified.Drug resistance test was conducted with K-B method.[Results]Of the 147 pathogenic bacteria isolated,Gram-Negative bacilli accounted for 70.07%(103),most of them were enteric bacilli.Of them Escherichia coli accounted for 48.98%(72);Gram-Positive cocci accounted for 26.53%(39/),of them Enterococcus accounted for 17.01%(25),Staphylococcus accounted for 9.52%;fungus accounted for 1.36%(2).Gram-negative bacilli had the lowest resistance to Imipenem and Cefotetan while had the highest resistance to Ampicillin,the resistance of Gram-positive cocci to Vancomycin and Linezolid was not detected,they had the highest resistance to Ciprofloxacin.[Conclusion]Urinary tract infection was mainly caused by the pathogenic bacteria of Entetobacteriaceae bacteria and Enterococcus.Rational use of antibiotics was very important to control urinary tract infection.
