SS Agar Medium
SS Agar Medium is a selective and differential medium primarily used for the isolation of Salmonella and Shigella species from clinical specimens. It contains a combination of nutrients and inhibitors, including peptone, agar, lactose, bile salts, ferric citrate, sodium citrate, sodium thiosulfate, beef extract, brilliant green, neutral red, and purified water. These components work together to suppress the growth of non-pathogenic bacteria while allowing the growth of Salmonella and Shigella.
Product English Name:
SS Agar Medium
Alias:
Salmonella-Shigella Agar,SS Medium
Intended Use:
SS Agar Medium is specifically designed for the selective isolation and differentiation of Salmonella and Shigella species. It is widely used in clinical laboratories, food testing, and environmental monitoring to detect these pathogens. The medium's selective properties inhibit the growth of Gram-positive bacteria and most coliforms, while its differential properties allow for the identification of Salmonella and Shigella based on colony color and morphology.
