DEOXYCHOLATE CITRATE AGAR MEDIUM (as per BIS)

Description

Deoxycholate Citrate Agar Medium is a moderately selective and differential plating medium used for isolating enteric bacilli, particularly Salmonella and many Shigella species. This medium utilizes sodium deoxycholate and sodium citrate to selectively isolate target pathogens. The organisms are differentiated in this medium on the basis lactose fermentation and on their ability to reduce ferric ammonium citrate to iron sulphide. The medium is in accordance with IS 5887(Part VII), 1999.
