Abstract
Since the first report of vancomycin-resistant enterococci (VRE) in 1992; the
prevalence of VRE in the hospitals has rapidly increased in Korea. VRE have emerged as a major
cause of nosocomial infections. The aims of present study were to determine the prevalence of
VRE; the genotype of VRE and to establish whether the isolates were clonally related. A total of
90 VRE isolates were collected from the patients admitted to Dongsan Medical Center from Jan to
Dec; 2006. Species identification and genotyping were evaluated with multiplex polymerase chain
reaction. Antimicrobial susceptibility test was determined by agar dilution methods according to
Clinical and Laboratory Standards Institute (CLSI). Pulsed field gel electrophoresis (PFGE) with
SmaI-restriction enzyme was also performed. The annual incidence of VRE was 16.2% in 2001;
19.4% in 2002; 16% in 2003; 23.7% in 2004; 24.7% in 2005 and 14.7% in 2006. VRE were
identified as E. faecium and E. faecalis in 71 (78.9%) and 19 (21.1%) isolates; respectively. All
VRE isolates were resistant to vancomycin. Only 75 VRE isolates were resistant to teicoplanin;
and 15 VRE isolates were susceptible or intermediate to teicoplanin which were interpreted as
VanB phenotypes. All VRE isolates carried the vanA gene. PFGE analysis showed that all 15 VRE.
faecalis from the nursery showed same patterns. Our data indicate that the annual prevalence of
VRE seems to decrease shortly but should surveil continuously afterward. VRE isolates of the
nursery that showed same PFGE pattern is probably due to the spread of an endemic clone within
the hospital. Therefore; further moleculoepidemiological evaluations would be needed
prospectively.
