VAN A AND VAN B VANCOMYCIN RESISTANT ENTEROCOCCI DETECTION MEDIA AND THE METHOD OF DETECTING THE ORGANISMS USING THE MEDIA

摘要

A medium for detecting ~VanA and VanB vancomycin-resistant enterococci (VRE) ~ whereby ~VanA and VanB VRE~, which are clinically important among VRE, can b e selectively grown; and a method of selectively detecting ~VanA and VanB VRE~ from test bacteria or test materials by using the above medium. Namely, a medium for detecting ~VanA and VanB VRE~ prepared by adding vancomyin, D- cycloserine and D-lactic acid to medium components wherein enterococci can b e grown; and method of selectively detecting ~VanA and VanB VRE~ from test bacteria or test materials by using the above medium. It is preferable to ad d from 32 to 256 .mu.g/ml of vancomycin, from 1 to 64 .mu.g/ml of D-cycloserin e and from 0.025 to 0.8 mol/l of sodium DL-lactate.
