The carbohydrates of whole cells of group A, B, C, D, F, and G streptococci were analyzed with a highly sensitive gas chromatographic procedure. Characteristic chromatographic fingerprints were obtained for each group of streptococci grown in broth cultures or as single colonies on a blood agar plate. Rhamnose, glucose, and N-acetylglucosamine were major components of all the groups. Groups A, C, and F contained very little galactose, and groups A and B showed almost a complete absence of N-acetylgalactosamine. Chromatograms obtained for group B streptococci were distinguished by the presence of 1,4-anhydroglucitol.
采用高灵敏度气相色谱法对A、B、C、D、F和G组链球菌全细胞的碳水化合物进行了分析。对在肉汤培养物中生长或在血琼脂平板上形成单菌落的每组链球菌都获得了特征性的色谱指纹图谱。鼠李糖、葡萄糖和N-乙酰葡糖胺是所有组的主要成分。A、C和F组几乎不含半乳糖，A组和B组几乎完全不含N-乙酰半乳糖胺。B组链球菌的色谱图以含有1,4-脱水葡萄糖醇为特征。
