SS agar is used as a selective medium for pathogenic enteric bacteria - usually used for Salmonella spp, but sometimes for Shigella spp (some of which may be inhibited). In addition, Proteus spp will form colourless colonies while any lactose fermenting organisms form pink colonies. Some H2S utilizing enterics will have black-centred colonies. Gram positive bacteria cannot grow on SS agar due to the high concentrations of brilliant green dye, sodium citrate, and bile salts.
