a
Interpretation of susceptibility patterns was performed following the current guidelines of CLSI (3) using MicroScan plates (Dade Behring, Deerfield, IL) and Etest strips to confirm resistance to vancomycin (Vanco), daptomycin (Dapto), or dalfopristin/quinupristin (Syn) (AB Biodisk, Piscataway, NJ). S, susceptible; R, resistant.
b
Numbers indicate PFGE patterns that differed by more than four bands.
