Analysis of bacterial distribution and antimicrobial susceptibility of community-acquired urinary tract infection

Objective To investigate bacterial distribution and antimicrobial susceptibility of pathogens causing community-acquired urinary tract infections(CAI),and propose rational use of antibiotics. Methods Bacteria were(isolated) and identified by routine methods.Antimicrobial susceptibility was tested by K-B methods. Results 263 strains of bacteria isolated from clinical urinary specimens of patients with CAI in our hospital.The most frequent pathogen found was Escherichia coli(64.3%),followed by Enterococcus(12.5%).Escherichia coli resistance to fluoroquinolones and ampicillin was significantly high. Conclusions The results indicate that bacteria causing CAI are obviously varied and drug resistance in the microbes is gradualy serious in this locality.
