BAIRD PARKER AGAR PLATE

Baird-Parker Agar Plate is a selective and differential culture medium for the enumeration of coagulase positive Staphylococci including Staphylococcus aureus in foods and clinical samples. The medium developed by Baird-Parker is characterized by high selectivity and excellent recovery of target organisms. It is AOAC International and USP recommended for Microbial Limit Tests and ISO for isolation and enumeration of Staphylococci.
The medium contains casein enzymatic hydrolysate and beef extract to supply essential carbon and nitrogen sources and yeast extract to supply B-complex vitamins to promote bacterial growth. The addition of sodium pyruvate enhances the survival of injured cells and the growth of Staphylococcus aureus, without altering the selectivity of the medium. Lithium chloride and glycine inhibit other microbes and therefore make the isolation more selective. Differentiation is based on lecithinase and lipolytic activities and the reduction of potassium tellurite produces typical black colonies like Staphylococcus aureus with egg yolk tellurite emulsion.
Its selective formulation and characteristic colony reactions make it a dependable medium for routine microbiological testing and quality assurance, allowing for dependable differentiation and reproducible results.

Designed for the selective isolation and enumeration of coagulase-positive Staphylococci through reliable differentiation based on lecithinase and tellurite reactions.
