ISOLATION AND ANTIMICROBIAL DRUG CHOICE OF ESCHERICHIA COLI IN URINARY TRACT INFECTION

[Objective]To understand the epidemic of Escherichia Coli in the urinary tract infection and it's sensitivity to 14 antibiotics,and to provide references for the clinical application of drugs.[Methods]128 strains Escherichia Coli infected urinary samples which were collected from 2008 to 2009 were carried out K-B method susceptibility test and ESBLs test.[Results]A total of 355 strains of the clinical isolates were isolated from 1 029 cases of urine samples.128 strains of them were the E.coli,and 65 producing ESBL bacteria was detected in 128 E.coli.It's positive rate was 50.8%.The best effect of killing bacteria was Imipenem.It's susceptibility was 100%,the secondly was Amikcacin(81.5%).[Conclusion]Escherichia coli is the most common clinical isolates of urine specimen,and the multidrug resistance was serious in the producing ESBL bacterias.Imipenem should be applied firstly in the treatment to the infection of the producing ESBL bacteria.
