Pathogens in Urinary System:Their Distribution and Resistance Analysis

OBJECTIVE To study the distribution and drug resistance of pathogens in urinary system,provide the credible evidence with the clinic diagnosis and the treatment of urinary diseases,and give doctors reasonable advice for medicine usage. METHODS The pathogens from the urine specimens were isolated and cultured from the patients in hospital from Jan 2003 to Dec 2004.The total 536 strains of pathogens were identified and the drug resistance was analyzed. RESULTS Escherichia coli among the pathogens infected the urinary system rated the top(57.0%),secondly were Enterococcus,Klebsiella,Staphylococcus,Pseudomonas aeruginosa and fungi.The drug resistance of E.coli to imipenem was the lowest,about 2.6%,however,it was above 30.0% towards the most beta-lactam antibiotics;the drug resistance of Enterococcus was generally higher,about 40.0-70.0%,but vancomycin was lower,about 10.3%. CONCLUSIONS The main pathogens are Enterobacteriaceae which infect the urinary system,the drug resistance is obviously higher to the quinolones,the clinic should reasonably choose the antibiotics according to the test results of the pathogens sensitivity to drugs.
