AGAR AGAR POWDER (as per IP) (Bacteriological Grade)

Description

Salmonella Differential Agar is slight modification of original formulation of Rambach used for differentiation of Salmonella species from Proteus species and other enteric bacteria. Production of acid from propylene glycol is a novel characteristic of Salmonella species and is utilized in these media. Many of the media such as SS Agar, XLD Agar recommended for the identification and differentiation of Salmonella species are based on lactose fermentation and hydrogen sulphide production. Other enteric gram-negative bacteria form colourless colonies. Salmonella Typhimurium and Salmonella Enteritidis produce pink to red colonies. Specimen should be enriched in an appropriate selective enrichment broth. This enriched culture is then inoculated on Salmonella Differential Agar, Modified and incubated at 35-37?C for 24-48 hours.
