ReadyPlate™ Baird Parker Agar is used for the isolation and enumeration of Staphylococcus aureus. Potassium chloride, lithium chloride, and glycine allow the media to be selective for Staphylococcusaureus. Sodium pyruvate is essential to recover the damaged S. aureus cells and their subsequent growth.Agar is the solidifying agent. Staphylococcus colonies show two characteristic features when grown in this medium: (a) characteristic zones and rings are formed because of lipolysis and proteolysis, and (b) reduction of tellurite to tellurium produces a black coloration. The egg-yolk reaction and tellurite reduction usually occur together with a positive coagulase reaction and thereby serve as an index for the latter. According to EN ISO 6888-1, sulfamethazine addition is advised to suppress the growth and swarming of Proteus spp., if these are suspected in the test sample.
