Distribution of Pathogenic Bacteria in Urinary System Infection and Their Drug Resistance

Objective To analyze the pathogenic bacteria's distribution and their drug resistance in urinary system infection,and to provide the information for choosing suitable antibiotic. Methods The pathogens from the urine specimens were isolated and cultured from the patients in hospital from Oct 2007 to Sep 2009. The total 286 strains of pathogens were identified and the drug resistance was analyzed. Results In the 286 strains of bacteria,67. 8% were Gram-negative and 32. 2% were Grm-positive. Most of Gram-negative bacteria were Escherichia and most of Grm-positive bacteria were Enterococcus. 34% of Escherichia produced ESBLs and the total rate of producing ESBLs was 26. 3%. The bacteria showed different antibiotic resistance rate and multi-drug resistance. Conclusion It's very important for making the clinical use of antibiotic more reasonable and controlling drug resistance strains transmission.
