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

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.

For differentiation of Salmonella species from members of Enterobacteriaceae especially Proteus species.
