Thermo ScientificTM OxoidTM
Isolate Salmonella and Shigella from clinical specimens and foods with selective Thermo Scientific™ Oxoid™ XLD Agar (Dehydrated). The medium relies on xylose fermentation, lysine decarboxylation and production of hydrogen sulphide for the primary differentiation of shigellae and salmonellae from non-pathogenic bacteria. The careful addition of sodium desoxycholate inhibits the growth of coliforms without decreasing the ability to support shigellae and salmonellae.
