Thermo Scientific™ SS Agar (Dehydrated)

Description

• 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
• Salmonella and Shigella are major causes of bacterial enteric illness with transmission occurring via the fecal-oral route, person-to-person contact, or by the ingestion of contaminated food or water
• SS Agar is a differential, selective medium for the isolation of Shigella and Salmonella species from pathological specimens, suspected foodstuffs etc
• Easy-to-read : lactose fermenters (red colonies) are easy to differentiate from non-lactose fermenters like Shigella and Salmonella (straw colorless colonies)
• Selective : due to the inclusion of selective inhibitory substances brilliant green, bile salts, thiosulphate, and citrate, most Gram-positive and coliform organisms are inhibited
• Thiosuplate in combination with iron acts as an indicator of sulphide production, which is indicated by blackening in the centers of the colonies
• Not all products are available for sale in all territories
