Here we report the presence and expression levels of the vanC
1 and vanC
2/3 genes in vancomycin-susceptible strains of
Enterococcus faecalis
. The vanC
1 and vanC
2/3 genes were located in the plasmid DNA and on the chromosome, respectively. Specific mRNA of the vanC
1 gene was detected in one of these strains. Additionally, analysis of the vanC gene sequences showed that these genes are related to the vanC genes of
Enterococcus gallinarum
and
Enterococcus casseliflavus
. The presence of vanC genes is useful for the identification of
E. gallinarum and
E. casseliflavus. Moreover, this is the first report of vanC mRNA in
E. faecalis.
