Thermo ScientificTM OxoidTM
Isolate and identify Salmonella and Shigella species from clinical or food samples with Thermo Scientific™ Oxoid™ SS Agar (Dehydrated). Differentiation of Salmonella and Shigella is achieved by incorporation of lactose in the medium. Organisms which ferment lactose produce acid which, in the presence of the neutral red indicator, results in the formation of red colonies. Salmonella, Shigella, and other non-lactose-fermenting organisms appear as transparent or straw coloured colonies on SS Agar.
