Wilson Blair Agar Base
Details
This medium is recommended for isolating Salmonella species especially Salmonella Typhi from clinical specimens. The medium is highly selective for Salmonellae, being inhibitory to coliforms, Proteus and Shigellae ; occasional strains of coliforms grow to form dull green or brown colonies, but without a surrounding metallic sheen. The medium is also suitable for the isolation of lactose-fermenting strains of Salmonellae, which can not be differentiated on lactose containing differential media since lactose is not the fermentable substrate used in this medium.
