Vancomycin Resistant Enterococci (VRE) Agar Baseis recommended for selective isolation of vancomycin resistant Enterococci.It is formulated as per the recommendations of Centre for Disease Control and Prevention (CDC) for the selective isolation of vancomycin resistant enterococci. Vancomycin Supplement (FD261) helps in the selective isolation of vancomycin resistant enterococci from other enterocci. Meropenem Supplement (FD262) added to the medium helps to suppress the contaminating flora especially gram-negative bacteria. Enterococci species hydrolyze esculin to glucose and esculetin.The latter combines with ferric ions of ferric ammonium citrate to forma dark brown or black complex visualized as a zone of black precipitate around the colonies.
