SS AGAR (SALMONELLA SHIGELLA AGAR) (VEG.)

SS Agar (veg) is prepared by using vegetable peptones in place of animal based peptones which makes the medium free of BSE/TSE risks. SS agar (veg) is the modification of SS Agar which is recommended as a differential and selective medium for the isolation of Salmonella and Shigella species from pathological specimens and suspected foodstuffs. Sodium thiosulphate is reduced by certain species of enteric organisms to sulphite and H2S (hydrogen sulphide) and this reductive enzyme process is attributed by thiosulphate reductase. Production of H2S is detected as an insoluble black precipitate of ferrous sulphide, formed upon reaction of H2S with ferric ions or ferric citrate, indicated in the centers of the colonies.
