Distribution and Antibiotic Resistance of Pathogenic Bacteria in Patients with Urinary Tract Infections

OBJECTIVE:To analysis the distribution and antibiotic resistance of common isolated pathogenic bacteria in urinary-tract infection cases in our hospital so as to provide scientific basis for the rational clinical use of antibacterials.MET-HODS:625 urine samples were collected from urinary-tract infection cases in our hospital in 2006,from which,344 strains of bacteria were isolated,which were cultured and subjected to drug sensitivity test.RESULTS:Of the 344 strains of bacteria,Gram-negative bacilli took the lead,accounting for 60.2% of the total,followed by Gram-positive cocci(33.4%) and fungi(6.4%).The detection rates of ESBLs-producing Escherichia coli.and Klebsiella pneumoniae were 49.2% and 27.3%,respectively.The bacteria had different resistant rate to different antibiotics and were multidrug resistant.CONCLUSION:Bacterial culture of urine and drug-sensitivity test should be performed promptly and drugs should be used with prudence for urinary infection cases to reduce drug-resistance bacteria.
