A collection of 19 strains of alpha haemolytic streptococci, isolated from throat swabs and characterized by production of spreading zones around colonies on blood agar, was found to constitute a very homogeneous group with morphological, physiological and biochemical characters corresponding to those of streptococci of ser-group H, or Streptococcus sanguis, and they all appeared to possess the group H antigen. They all had a common agglutinogen and, in addition, heterogeneous agglutinogens. The spreading growth, which appears to be a common property of S. sanguis, was due to twitching motility, and the spreading cultures possessed polar fimbriae. tneither twitching motility nor the possession of polar fimbriae have been observed in gram-positive bacteria before.
从咽拭子中分离出19株α溶血性链球菌，其特征是在血琼脂平板上菌落周围产生扩散区。结果发现，这些菌株构成了一个非常同质的群体，其形态、生理和生化特征与血清H组链球菌或血链球菌一致，并且它们似乎都具有H组抗原。它们都有一个共同的凝集原，此外还有异质凝集原。扩散生长似乎是血链球菌的一个共同特性，这是由于菌毛运动引起的，并且扩散培养物具有极生菌毛。以前在革兰氏阳性菌中未观察到菌毛运动和极生菌毛的存在。
