alpha-haemolytic streptococci, classified as Streptococcus sanguis, with spreading growth due to twitching mobility were isolated from 41% of 121 swab cultures from the human pharynx. Sixty-five out of 70 isolates with spreading growth belonged to Lancefield's group H, while 5 isolates constituted a new serological entity. None of 159 non-spreading alpha-haemolytic streptococci isolated from the same cultures possessed either of these antigens. An examination of strains of types I, II and I/II described by Washburn et al., in the group H antisera employed in the present study indicated that type I and type I/II differ from one another in the degree of cross-reactivity with anti-type II serum. (The type II antigen was not demonstrated in any of the isolated strains). We support the opinion that type II should not be considered as S. sanguis.
从121份人类咽部拭子培养物中，41%分离出了α-溶血性链球菌，归类为血链球菌，因抽动运动而呈扩散生长。70株具有扩散生长的分离株中，65株属于兰斯菲尔德H组，5株构成一个新的血清学实体。从相同培养物中分离出的159株非扩散性α-溶血性链球菌均不具有这些抗原中的任何一种。对沃什伯恩等人描述的I型、II型和I/II型菌株，在本研究使用的H组抗血清中进行检测，结果表明I型和I/II型与抗II型血清的交叉反应程度不同。（在任何分离菌株中均未证实有II型抗原）。我们支持不应将II型视为血链球菌的观点。
