Wilson Blair HiVeg Agar Base, 500G

This animal free 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 dullgreen 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. Application: For the Isolation of Salmonellae Particularly Salmonella Typhi, Animal Free Media, WB BBS HiVegTM Agar Appearance of powder: Light yellow coloured, may have slightly greenish tinge, homogeneous, free flowing powder Gelling: firm, comparable with 3.0% agar gel Colour and clarity: basal medium yields light yellow coloured, clear to slightly opalescent gel, With addition of selective reagent greenish yellow coloured opaque gel forms in petri plates Reaction of 6.0% w/v aqueous solution is pH 7.3 ± 0.2 at 25°C Cultural characteristics observed with added selective reagents after an incubation at 35 - 37°C for 24 - 48 hours
