Oxoid™ Baird Parker Agar 5kg

Oxoid™ Baird-Parker Agar (5kg) is a selective and differential medium used for the isolation and enumeration of Staphylococcus aureus from food, environmental, and clinical samples. The medium is enriched with egg yolk emulsion and contains potassium tellurite, which selectively inhibits most other microorganisms while promoting the growth of S. aureus. S. aureus typically forms black colonies, often with a clear zone due to lecithinase activity, making it easily identifiable. This agar is ideal for use in food safety testing and microbiological research.

Key Features:

• Form: Dehydrated powder.
• Weight: 5kg.
• Application: Isolation and enumeration of Staphylococcus aureus'
• Composition: Contains potassium tellurite to inhibit non-Staphylococcus species and egg yolk emulsion to detect lecithinase production; provides nutrients to support the growth of S. aureus.
• Preparation: Suspend 52g of the dehydrated medium in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes. Sterile egg yolk emulsion can be added if required.
• Yield: Approximately 100 litres of prepared medium.
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light.
