Various nutrient bases (dry nutrient agar, erythrol agar, medium for toxigenicity determination, casein-yeast and AGV media) have been examined to choose a base for Pizu's medium instead of agar D that is no longer manufactured. AGV medium has been found the best nutrient base. The method for the preparation of Pizu's medium has been simplified. The modified Pizu's medium permits the detection of cystinase in C: diphtheriae in 3-5 hrs both in pure and mixed cultures.
已对多种营养基础培养基(干燥营养琼脂、赤藓醇琼脂、产毒测定培养基、酪蛋白酵母培养基和AGV培养基)进行了检测,以选择一种培养基来替代不再生产的琼脂D作为皮祖培养基的基础培养基。已发现AGV培养基是最佳的营养基础培养基。简化了皮祖培养基的制备方法。改良后的皮祖培养基能够在3至5小时内检测出纯培养物和混合培养物中白喉棒状杆菌的胱氨酸酶。
