Abstract:
OBJECTIVE To study the clinical species distribution and drug resistance of Enterococcus.METHODS We had collected 201 isolates of Enterococcus by cultured in normal methods in our hospital from July 2005 to June 2008,and analyzed the characteristics of species distribution,drugsensitive test,drug resistance of high concentration aminoglycoside antibiotics and measured the ?-lactamase.RESULTS There are 106 E.faecalis strains(52.7%),76 E.faecium strains(37.8%) and 19 the other Enterococcus strains(9.5%).There were 102 Enerococcus strains separated from urine and 46 separated from sputamentum.The drug resistance rate of Enterococcus faecalis to erythromycin,tetracycline,rifampin and ciprofloxacin were more than 75.0% and the resistance rate of E.faecium to penicillin,ampicillin,erythromycin,rifampin,ciprofloxacin and nitrofurantoin were more than 93.0%;the total resistance rate of Enterococcus to vancomycin and teicoplanin were 14.4% and 10.4%,respectively.The number of the isolates resistant to high concentration aminoglycoside antibiotics was 151(75.1%);Enterococcus with positive ?-lactamase were 74(36.8%).CONCLUSIONS The infection in urinary system and respiratory system were mainly caused by E.faecalis and E.faeciumwith multidrug resistance.
