Susceptibility to Vancomycin: E. faecium & E. faecalis

Vancomycin-resistant enterococci (VRE) first appeared in Europe during the 1980s. It rapidly spread to North America by the 1990s. 

Susceptibility:

More than 50% of E. faecium in the United States are VRE.

E. faecalis tends to be susceptible to vancomycin.

Most frequent form of VRE infection: UTI, followed by catheter line associated bacteremia (i.e hemodialysis, central lines).

Treatment for VRE: daptomycin, linezolid, and tigecycline. Susceptible strains may be treated with ampicillin.
