Among 86, mostly twitching, polarly fimbriated strains of Streptococcus sanguis, 55 agglutinated guinea pig erythrocytes (GPE) after cultivation in Todd-Hewitt broth (TH), and 21 strains agglutinated GPE only after growth in TH with 10% horse serum (THS). Two of the positive strains were non-twitching and unfimbriated. Ten strains failed to haemagglutinate. Among 5 twitching strains belonging to the 10043 group, 3 agglutinated GPE after growth in TH and 2 only after growth in THS. Among 35 non-twitching strains of alpha-haemolytic streptococci, only 6 agglutinated GPE after growth in TH, and among 8 negative strains which were tested after growth in THS, only 1 agglutinated GPE. Tests using 6 different kinds of erythrocytes (guinea pig, rabbit, sheep, horse, chicken, human) revealed that differences between these were slight only. The results do not indicate that there is an absolute association between twitching and haemagglutination in S. sanguis. The haemagglutination of S. sanguis was not mannose-sensitive.
在86株主要呈抽搐状、极纤毛化的血链球菌菌株中，55株在托德 - 休伊特肉汤（TH）中培养后能凝集豚鼠红细胞（GPE），21株仅在含10%马血清的TH（THS）中生长后才凝集GPE。其中两株阳性菌株不呈抽搐状且无纤毛。10株未能发生血凝。在属于10043组的5株抽搐状菌株中，3株在TH中生长后凝集GPE，2株仅在THS中生长后凝集。在35株α - 溶血链球菌的非抽搐状菌株中，仅6株在TH中生长后凝集GPE，在8株经THS培养后检测的阴性菌株中，仅1株凝集GPE。使用6种不同类型红细胞（豚鼠、兔、羊、马、鸡、人）进行的试验表明，这些红细胞之间的差异很小。结果并不表明血链球菌的抽搐与血凝之间存在绝对关联。血链球菌的血凝对甘露糖不敏感。
