Vaginalis Agar Base is recommended for the qualitative isolation and differentiation of Gardnerella vaginalis from clinical specimens. It is used for the isolation of G. vaginalis from vaginal discharges. This medium is recommended for determination of haemolytic reaction of G. vaginalis and not for other microorganisms. If the specimen is suspected to contain streptococci or other haemolytic microorganisms, then a Soyabean Casein Digest Agar (with 5% v/v sheep blood) plate should be inoculated parallel to this medium to ensure the haemolytic reaction.
