Oxoid™ Bismuth Sulfite Agar 500g

Oxoid™ Bismuth Sulfite Agar (500g) is a selective and differential medium used for the isolation and differentiation of Salmonella species, particularly Salmonella typhi, from clinical and environmental samples. The medium contains bismuth sulfite, which inhibits the growth of most other microorganisms, whilst allowing the growth of Salmonella species. The medium’s colour changes depending on the biochemical reactions of the bacteria, providing a visual indication of Salmonella presence.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Isolation and differentiation of Salmonella species
• Composition: Contains bismuth sulfite and other selective agents to inhibit non-Salmonella organisms; includes nutrients to support the growth of Salmonella
• Preparation: Suspend 42g of the dehydrated medium in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 12 litres of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
