Abstract:
OBJECTIVE To realize the present resistance characteristics of enterococci to common antimicrobial agents,and to provide reference for clinical therapy. METHODS A total of 79 isolates of enterococci were collected from samples during the period of 2000-2003.The broth microdilution test and ?-lactamase determination were performed for each of the strains.The laboratory data were analyzed. RESULTS The rates of Enterococcus faecalis and E.faecium were 73.4%,and 26.6% of all enterococci isolates.The most common sites of infection were urinary tract(35.4%),surgical secretion(24.1%),and sputum(15.2%).The rate of E.faecium approached 50% of enterococci in urinary tract.The antibiotic resistance of E.faecium was more than E.faecalis to ampicillin,penicillin,and rifampin.The ratio of HLAR enterococci and VRE to total enterococci isolates were 61.9% and 0;?-lactamase producing rate was 6.3%. CONCLUSIONS Urinary infection caused by enterococci is most frequent.E.faecium is found more easily in urinary tract than in the others and very resistant to antibiotics.Vancomycin shows fairly high activity against enterococci.The different regimens should be adopted for different enterococci.
