Distribution and drug resistance of pathogenic bacteria in urinary system infection

Objective To investigate the distribution and drug resistance of pathogenic bacteria in patients with urinary system infection in our area,so as to provide reference for clinical therapy.Methods A total of 380 strains isolaed from urine specimens of inpatients and outpatients from Jan 2005 to Dec 2006 were identified and the drug resistance test was performed.Results A total of 380 strains were isolated.The former four ranks were Escherichia coli(248/380,65.3%),Staphylococcus aureus(53/380,8.7%),Enteroccus coccus(37/380,9.7%) and Pseudomonas aeruginosa and fungi.The resistance rate of gram positive bacteria negative bacillus to vancomycin was 100%.For Enteroccus bacillus,the most sensitive antibiotic was imipenem.Conclusion The resistance rate of pathogenic bacteria tends to increase during urinary tract infection.Rational use of antibiotics should be carried out according to urine culture result.
