Product Code TM 2314

  • Description

    SS Selective Agar, Improved is recommended as selective medium for the isolation of Salmonella as well a Shigella species from clinical specimens. It provides significantly greater sensitivity and specificity in the detection of both the organisms. The other selective medias like HE, SS and XLD largely fail to suppress the growth of Salmonella interfering organism like Citrobacter and Proteus which resemble the presence of Salmonella. Bacteria that decarboxylate lysine to cadaverine can be recognized by the appearance of a red colouration around the colonies due to an increase in pH. Sodium thiosulphate is reduced by certain species of enteric organisms to sulphite and H2S gas and this reductive enzyme process is attributed by thiosulphate reductase.
