Baird-Parker agar is a type of agar used for the selective isolation of gram-positive Staphylococci species.[1] It contains lithium chloride and tellurite to inhibit the growth of alternative microbial flora, while the included pyruvate and glycine promote the growth of Staphylococci.[1] Staphylococcus colonies show up black in colour with clear zones produced around them.[1]
