Vancomycin-resistant Enterococcus faecium (VREF) in
human infections mostly belong to the high-risk, epidemic,
clonal complex-17 (CC17) group. Treatment limitation and
high conjugation frequency makes it dominant in hospitals
worldwide. We investigated positive cultures by Pulse-field
gel electrophoresis (PFGE), multi locus sequence typing
(MLST). DNA of two strains (A2 and C) appeared to be
clonally related by PFGE. Three strains were of ST 18 type
(A1, B and C) and strain A2 is of a new ST 596. This ST 18
type strain found in our study is crucial and is believed to be the first in Malaysia.
