Baird-Parker agar

History

Baird-Parker Agar From Liofilchem first published an academic article about this agar medium for the purposes of improved diagnostics and isolating coagulase-positive Staphylococci in 1962. He developed this agar medium from the tellurite-glycine formulation of Zebovitz et al and improved its reliability in isolating coagulase-positive staphylococci from foods. Baird-Parker added egg yolk emulsion as a diagnostic agent and sodium pyruvate to protect damaged cells and aid their recovery. It is now widely recommended by national and international bodies for the isolation of coagulase-positive staphylococci. Baird-Parker agar is commonly used as a method for the enumeration of coagulase-positive staphylococci (Staphylococcus aureus and other species) in food and animal feedstuffs.
