The potassium tellurite concentration, 0.01% w/v, in Baird-Parker agar has been recommended for plasma coagulase media such as pig or rabbit fibrinogen agar. Comparative tests have shown that with some strains of Staphylococcus aureus this level of potassium tellurite is too inhibitory and it should be reduced four-fold to 0.0025% w/v to maximize the isolation rate. It is postulated that egg yolk in Baird-Parker agar has a protective effect on staphylococci against the inhibitory action of tellurite.
已推荐在贝尔德-帕克琼脂中使用浓度为0.01%（w/v）的亚碲酸钾，用于血浆凝固酶培养基，如猪或兔纤维蛋白原琼脂。对比试验表明，对于某些金黄色葡萄球菌菌株，这种亚碲酸钾水平的抑制作用过强，应将其降至四分之一，即0.0025%（w/v），以使分离率最大化。据推测，贝尔德-帕克琼脂中的蛋黄对葡萄球菌具有保护作用，可抵抗亚碲酸盐的抑制作用。
