Distribution of Bacteria in Urinary Tract Infection and Drug Resistance of Escherichia coli

Objective To investigate the distribution of bacteria and drug resistance of Escherichia coli in urinary tract infection, and to provide the reference for rational use of antibiotics in clinic. Methods Bacteria were detected with ATB Expression system. K-B method was applied for the drug susceptibility test. Results Among the 2,350 detected urine samples, the positive rate of urine cultures was 31.74% and 746 bacterial strains were detected. The detection rate of Escherichia coli was the highest (50.41%, 376/746) among the urinary tract infection, followed by Enterococcus (16.35%, 122/746), fungus (13.41%, 100/746), and Klebsiella pneumoniae (9.12%, 68/746). Escherichia coli were highly sensitive to piperacillin/tazobactam, amikacin and imipenem. Conclusions The isolated rate of urine samples is high in the First People’s Hospital of Huaihua. It is of great significance to decrease nosocomial infections and guide rational use of antibiotics by urine cultures.
