Vancomycin-resistant
Enterococcus faecalis coisolated with vancomycin-resistant
(VanA) Staphylococcus aureus was found to contain two
plasmids, designated pAM830 (45 kb) and pAM831 (95 kb). pAM830, found
to be conjugative and closely related to the Inc18 family of
broad-host-range conjugative plasmids, encodes resistances to
vancomycin (via a Tn1546-like element) and erythromycin;
pAM831 encodes resistances to gentamicin, streptomycin, and
erythromycin.
