Bismuth sulfite agar (BS)

Bismuth sulfite agar (BS)

Bismuth sulfite agar (BS) is a highly selective separation medium, which is specially used to directly separate Salmonella typhi and other Salmonella from patients' feces or food samples. Its selectivity comes from high concentration of bismuth sulfite and brilliant green, which can strongly inhibit the growth of Escherichia coli, Proteus and other miscellaneous bacteria and gram-positive bacteria. Salmonella can reduce bismuth sulfite to bismuth sulfide, which makes typical colonies appear black or brown with metallic luster. The medium around the colony usually turns black due to reduction. Brilliant green further inhibits non-salmonella. This culture medium has special discrimination against Salmonella typhi, and it is the key separation plate in the standard detection process of Salmonella.
