Abstract:
Objective To investigate the antimicrobial resistance of Enterococcus f aecalis and Enterococcus f aecium isolated from the First Affiliated Hospital of Chongqing Medical University between 2009 and 2012 .Methods Antimicrobial susceptibility testing was carried out according to the unified protocol .The dates were analyzed by WHONET 5 .6 software according to clinical and laboratory standards institute(CLSI) of 2012 .Results A total of 783 non-repetitive Enterococcus f aecalis and 664 non-repeti-tive Enterococcus f aecium isolates were collected .The strains were still highly susceptible to linezolid and vancomycin .The resist-ance rates were all less than 2 .0% .The resistance rates of vancomycin to Enterococcus f aecalis and Enterococcus f aecium were 0 .1% and 1 .4% ,respectively .The percentage of Enterococcus f aecalis resistant to ampicillin ,penicilin and nitrofurantoin were 5 .7% ,2 .6% and 2 .2% ,respectively .About 32 .9% of Enterococcus f aecalis isolates were resistant to gentamicin .The resistance rates of ampicillin and penicillin to Enterococcus f aecium were more than 90 .0% .Conclusion Enterococcus f aecalis is main En-terococcus in the First Affiliated Hospital of Chongqing Medical University .There is an obvious difference between the antibiotic re-sistance of the Enterococcus f aecalis and Enterococcus f aecium .So ,monitoring drug resistance of the Enterococcus shows great sig-nificance to the clinical treatment .
