Trypsinized cell walls of Group B hemolytic streptococci are composed of a group-specific carbohydrate and mucopeptide. The carbohydrate extracted with hot formamide is composed of rhamnose, N-acetylglucosamine, and galactose. Quantitative precipitin inhibition studies have shown that L rhamose is the significant component of the antigenic determinant. The cross-reactivity between B and G carbohydrates is dependent upon the fact that Lrhamose is a determinant sugar in both antigens.
B 组溶血性链球菌经胰蛋白酶处理后的细胞壁由群特异性碳水化合物和粘肽组成。用热甲酰胺提取的碳水化合物由鼠李糖、N-乙酰葡糖胺和半乳糖组成。定量沉淀抑制研究表明，L-鼠李糖是抗原决定簇的重要成分。B 组和 G 组碳水化合物之间的交叉反应性取决于 L-鼠李糖在两种抗原中都是决定糖这一事实。
