For detection of Van A / Van B VRE. faecalis & VRE. faecium

Acquired Vancomycin resistance in E. faecalis and E. faecium has the potential to be transferred to aggressive pathogens. The efficiency of control measures to avoid their spread is dependent on the labs ability to rapidly detect VRE. The use of CHROMagar VRE media allows Vancomycin resistant E. faecalis and E. faecium to be easily detected by colony colour after only 24h of incubation

Typical appearance of microrganisms

VRE. faecalis/VRE.faecium → pink to mauve
E. gallinarum/E. casseliflavus → blue or inhibited

Other bacteria → inhibited

Simple, Fast and Reliable Tool: For the direct detection of VRE strains with transmissible resistance: This is a precious help in the implementation of the appropriate control measures to prevent the spread of VRE.

Intense Colony Colours: In the new CHROMagar VRE media, VRE. faecalis and VRE. faecium strains are easily distinguishable by the colony colour

Flexibility: CHROMagar VRE is supplied with a shelf-life of about 2 years. This allows for flexibility of use, whether in an epidemic situation with many patients to screen, or whether for random surveillance of cultures
