Baird Parker Agar was developed by Baird Parker from the Tellurite-glycine formulation for isolation and enumeration of Staphylococci in food and other material since it allows a good differentiation of coagulase positive strains. It is also being used for the isolation and enumeration of Staphylococci.
Tryptone, HM peptone B and yeast extract are sources of nitrogen, carbon, sulphur and vitamins. Sodium pyruvate not only protects injured cells and helps recovery but also stimulates Staphylococcus aureus growth without destroying selectivity. Lithium chloride and potassium tellurite inhibit most of the contaminating microflora except Staphylococcus aureus. The tellurite additive is toxic to egg yolk-clearing strains other than S.aureus and imparts a black colour to the colonies. Glycine, pyruvate enhances growth of Staphylococcus . With the addition of egg yolk, the medium becomes yellow, opaque. The egg yolk additive, in addition to provide enrichment, aids in the identification process by demonstrating lecithinase activity (egg yolk reaction).
