In group A and A-variant streptococcal antisera the presence of antibodies reacting with group L streptococcal polysaccharide (L polysaccharide) was revealed. Group A and A-variant streptococcal polysccharides (A and V polysaccharides) were shown to be partially identical to L polysccharide by means of the precipitation test in agar gel. Experiments in inhibiting the reactions of the above mentioned antisera with A, V and L polysaccharide preparations suggest the presence of a determinant common to all these polysccharides and differing from the "ramnose" determinant of the polysaccharides and from the determinant characteristic of A polysaccharide. In the identification of group A streptococci by the immunological methods, as well as in the study of cross reactions with the tissues of mammals, the possible presence of antibodies against various antigenic determinants of A polysaccharide, one of which is also common to L polysaccharide, should be taken into consideration.
在A组和A变异型链球菌抗血清中，发现存在与L组链球菌多糖（L多糖）发生反应的抗体。通过琼脂凝胶沉淀试验表明，A组和A变异型链球菌多糖（A和V多糖）与L多糖部分相同。抑制上述抗血清与A、V和L多糖制剂反应的实验表明，所有这些多糖存在一个共同的决定簇，该决定簇不同于多糖的“鼠李糖”决定簇以及A多糖的特征性决定簇。在通过免疫学方法鉴定A组链球菌以及研究与哺乳动物组织的交叉反应时，应考虑可能存在针对A多糖各种抗原决定簇的抗体，其中之一也是L多糖所共有的。
