Description
VRESelect is a selective and differential chromogenic medium, containing 8 μg/mL of vancomycin, for the qualitative detection of gastrointestinal colonization of vancomycin resistant Enterococcus faecium (VREfm) and vancomycin resistant Enterococcus faecalis (VREfs) and to aid in the prevention and control of vancomycin-resistant Enterococcus (VRE) in healthcare settings. The test procedure is simple, and results are easy to read and interpret. The selectivity of the VRESelect is based on the presence of an antifungal/antibiotic mixture that inhibits the growth of most yeasts, Gram negative and Gram positive bacteria, with the exception of VRE.
Detection is based on the cleavage of chromogenic substrates by specific enzymes of Enterococcus faecium which produces pink colonies and Enterococcus faecalis which produces blue colonies.
The test is FDA-cleared for use with rectal swabs and fecal specimens from patients to be screened for VRE colonization.
Results can be interpreted after 24 to 28 hours incubation.
