Baird-Parker (BP) Agar is a selective and differential medium used for the isolation and presumptive identification of coagulase-positive Staphylococcus from clinical specimens, foods, air, water, and other materials. Colonies of S. aureus form a characteristic black pigmentation by reducing the potassium tellurite and form clear zones due to proteolysis of the egg yolk emulsion. Lecithinase or lipase production results in the formation of a smaller, opaque zone within the clear zone. • Product meets AOAC, BAM, CLSI, EP, ISO, NF, SM-Dairy, SMWW, and USDA reference methods and performance criteria.• BP Agar should be used by trained professionals within a laboratory setting. • For in vitro diagnostic (IVD) use.• Product is not intended for use in the diagnosis or treatment of disease or other human conditions.
