Hynes Desoxycholate Citrate Agar (Dehydrated)

Isolate and differentiate Salmonella and Shigella species from clinical samples easily and with improved selectivity using Thermo Scientific™ Oxoid™ Hynes Desoxycholate Citrate Agar (Dehydrated).

The medium is pale pink and clear. Lactose fermenting organisms produce pink colonies and may be surrounded by a zone of precipitated desoxycholic acid. The colonies of non-lactose fermenters are colorless, and, due to their alkaline reaction, they are surrounded by a clear orange-yellow zone of medium.

An improved medium, based on the Hynes¹ modification of Leifsons² medium, Desoxycholate Citrate Agar (Hynes Modification) makes the isolation of salmonellae and shigellae easier.

• Easier colony selection: improved medium gives larger and more numerous colonies of Shigella species which can easily be picked off and emulsified in saline for slide agglutination tests
• Improved selectivity: more inhibitory to coliforms and Proteus species than the original Desoxycholate Citrate Agar (Part No. CM0035B)
