学习了“优选法”,我们对分离肠道致病菌的SS培养基中的主要成分——自制胆盐(代替进口胆盐)的用量进行了试验。我们是应用优选法的单因素折纸法,首先把培养基的其他成份固定下来,优选胆盐的用量。从8—10克的范围内的胆盐定了四个点(因检材来源关系),并以进口胆盐为对照, Studying the “preferred method”, we tested the amount of home-made bile salt (instead of imported bile salts), the main component of the SS medium for isolating enteric pathogens. We are the single factor origami method of applying the optimization method, first of all the other components of the medium are fixed, preferably the amount of bile salts. From the 8-10 grams of bile salt in the context of the four points (due to the source of the sample), and to import bile salts as a control,
