Fresh isolates of Streptococcus mutans, Streptococcus sanguis, and Streptococcus salivarius from human dental plaque were all highly hydrophobic. After repeated subculture in vitro on blood agar, strains of S. mutans serotype c showed decreased hydrophobicity, whereas serotype d/g strains did not. Parallel to the decreased hydrophobicity in the serotype c strains, an impaired ability to adhere to hydroxyapatite was observed. A similar but less pronounced decrease in hydrophobicity in one S. sanguis strain resulted in a marked decrease in adherence to hydroxyapatite.
从人类牙菌斑中分离出的变形链球菌、血链球菌和唾液链球菌新鲜菌株均具有高度疏水性。在血琼脂上进行多次体外传代培养后，变形链球菌c血清型菌株的疏水性降低，而d/g血清型菌株则没有。与c血清型菌株疏水性降低同时出现的是，观察到其黏附羟基磷灰石的能力受损。一株血链球菌菌株的疏水性也出现了类似但不太明显的降低，导致其对羟基磷灰石的黏附显著减少。
