Abstract:
OBJECTIVE In order to supply the basis of reasonable use of antibiotics,investigation of the change in distribution and drug-resistance of isolated enterococci was made in our hospital.METHODS Enterococci were cultured,isolated and identified with ATB Expression microbe identification system.Drug-resistance was detected with ATB ENTEROC and was statistically analyzed.RESULTS A total of 1 354 strains of enterococci were isolated from 50 148 clinical specimens,the isolation rate was 2.7%.The main strain of enterococci was Enterococcus faecalis.E.faecium was the second one.The isolation rate of enterococci,which were the highest in urine specimens,was increasing in sputum specimens year by year.The drug-resistance rate of enterococci to erythromycin,rifampin,ciprofloxacin and levofloxacin was high,but it was still sensitive to vancomycin and teicoplanin.CONCLUSIONS Great changes have taken place in bacterial distribution and drug-resistance of isolated enterococci,and the drug-resistance of strains of enterococci differed greatly.To insure effective treatment and decrease the infection of enterococci in hospital,the antibiotics sensitive to enterococci should been used on the basis of drug-resistance test when the infection of enterococci was treated clinically.
