128 M- and 15 T-typed strains of A-streptococci were investigated in respect of their streptolysin O production. The peak of streptolysin O production was reached after the logarithmic growth-phase and persisted for more than 24 h. The strains were classified in very weak 44% (0-1,0 E/ml), weak 30% (1,5-3,0 E/ml), medium 21% (4-8,0 E/ml) strong 5% (12-48 E/ml), 9 strains (7%) produced no detectable streptolysin O. The amount of streptolysin O necessary for antigen stimulation is discussed. A connection of growth character and enzyme production was not observed.
对128株M型和15株T型A组链球菌进行了链球菌溶血素O产生情况的研究。链球菌溶血素O的产生在对数生长期后达到峰值，并持续超过24小时。这些菌株被分类为：极弱（44%，0 - 1.0 E/ml）、弱（30%，1.5 - 3.0 E/ml）、中等（21%，4 - 8.0 E/ml）、强（5%，12 - 48 E/ml），9株（7%）未检测到链球菌溶血素O。文中讨论了抗原刺激所需的链球菌溶血素O的量。未观察到生长特性与酶产生之间的关联。
