Abstract

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.

[A群溶血链球菌产生溶血素O(作者译)]。

对128株M型和15株t型a型链球菌产链溶素O进行了研究。在对数生长期后达到产链溶素O的峰值，并持续24 h以上。菌株分为极弱44% (0-1,0 E/ml)，弱30% (1,5-3,0 E/ml)，中21% (4-8,0 E/ml)，强5% (12-48 E/ml)， 9株(7%)未产链溶素O。讨论了抗原刺激所需的链溶素O量。生长性状与产酶量之间没有联系。
