General description
Bismuth Sulfite Agar is a highly selective medium designed for the isolation and detection of Salmonella species, including Salmonella typhi, from food, water, and clinical samples. The medium′s selectivity is achieved through the combined action of freshly precipitated bismuth sulfite and brilliant green, which effectively suppresses the growth of coliforms while permitting the growth of salmonellae. Sulfur compounds in the medium provide a substrate for hydrogen sulfide production, and the metallic salts, stain the colonies and surrounding medium black or brown in the presence of hydrogen sulfide, providing a clear visual indicator for Salmonella identification.
