Pathogenic bacteria distribution and antibiotic resistance analysis of urinary system infection.

OBJECTIVE To study the distribution and drug resistance of pathogens in urinary system infection,provide the credible evidence with the clinic diagnosis and the treatment of urinary diseases.METHODS The pathogens from the urine specimens were isolated and cultured from inpatients and outpatients of hospital from Jan 2007 to Jun 2009.The total 340 strains of pathogens were identified and the antibiotics resistance was tested.RESULTS The Escherichia coli among the pathogens of the urinary system infection reached the top(62.30%),secondly were Enterococcus(12.35%)and Candida albicans(5.90%).The antibiotics resistance of E.coli to imipenem was the lowest,about 0%,however,it was above 60.0% towards the most beta-lactam antibiotics.To the quinolones,the drug resistance was obviously higher.The drug resistance of Enterococcus to vancomycin was 0-25.0%,but to the quinolones,macrolides,tetracyclines,and rifampicin was over 30.0%.CONCLUSIONS The main pathogen is E.coli which infects the urinary system of which the drug resistance is obviously higher.The clinics should reasonably choose the antibiotics according to the test results of the pathogens sensitivity to drug.
