Baird Parker Agar is a selective medium for Staphylococcus aureus (S. aureus) in food and other samples, as it allows good differentiation of coagulase-positive strains. This medium is also known as Staphylococcus Selective Agar. It is a synthetic medium. Sodium pyruvate has been added as a selective growth stimulant, and egg yolk emulsion as a differentiating agent.
