一般菌落溶血性状观察,均采用6—10％血琼脂平碟,每只平碟(直径7厘米)需血琼脂7—8毫升,需动物(兔或羊)血(?).6毫升左右。随着学生人数的加多,实验需要的动物血也大大地增加。为了节省用血,我们采用微量血碟法,并试用于学生实验,接种过金黄色葡萄球菌,乙型链球菌及甲型链球菌,效果良好。今就方法及优点介绍如下: General colony hemolytic traits were observed using 6-10% blood agar flat dish, each flat dish (7 cm in diameter) blood agar 7-8 ml, animals (rabbit or sheep) blood (?). 6 ml or so. With the increase in the number of students, the blood of animals required for the experiment also increased greatly. In order to save the use of blood, we use trace blood test, and try it on students’ experiments, inoculated with Staphylococcus aureus, Streptococcus B and Streptococcus A, the effect is good. Now on the methods and advantages described below:
