Chromogenic Surveillance

There are two types of vancomycin resistance in enterococci. The first type is intrinsic resistance (mostly Van C type but also Van D, Van E, Van F, etc) found in E. gallinarum and E. casseliflavus/E. flavescens and demonstrates a low-level resistance to vancomycin. The second type of vancomycin resistance in enterococci is acquired resistance (Van A & Van B types), mostly seen in E. faecium and E. faecalis.

Therefore, to avoid the spread of this resistance to more virulent pathogens (S. aureus, for instance) it is crucial to promptly detect the presence of any of these two species in the patient, and accurately differentiate them from other Enterococci.

COLOREX VRE prepared plated culture media is a selective and differential chromogenic medium, containing vancomycin, intended for use in isolation of pure cultures of vancomycin resistant Enterococcus faecium and Enterococcus faecalis (VRE) from laboratory samples. Further, colony color is used to differentiate transmissible forms of resistance (i.e., VanA & VanB resistance) from intrinsically resistant (i.e. VanC, VanD, VanE, etc.) strains.
