Oxoid™ Baird Parker Medium Base (ISO) (500g) is a selective and differential medium used for the isolation and enumeration of Staphylococcus aureus from food, dairy, and environmental samples. Developed according to ISO 6888 standards, it supports the recovery of coagulase-positive Staphylococci, with characteristic colony morphology that aids in identification. Supplementation with egg yolk tellurite emulsion enhances both selectivity and differentiation.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Isolation and enumeration of Staphylococcus aureus in food and environmental samples, as per ISO 6888 standards
• Composition: Peptones, yeast extract, glycine, sodium pyruvate, lithium chloride, and selective agents; requires supplementation with egg yolk tellurite emulsion for full functionality
• Preparation: Suspend 63g in 1 litre of distilled water, mix thoroughly, and boil to dissolve completely; do not autoclave. Cool to 50°C and aseptically add reconstituted egg yolk tellurite emulsion before pouring plates
• Yield: Approximately 7.9 litres of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Complies with ISO 6888 for the detection of coagulase-positive Staphylococci, including S. aureus, in microbiological testing
