Fifteen strains of Streptococcus sanguis biotype I and eight strains of Streptococcus sanguis biotype II with peritrichous fibrils, tufts of fibrils or a mixture of fibrils and fimbriae on the cell surface, were tested for their ability to adhere to saliva coated spheroidal hydroxyapatite (S-SHA) in a radiolabelled assay. S. sanguis I strains adhered better than S. sanguis II strains and peritrichously fibrillar strains generally adhered better than tufted strains. There was no correlation between the density of fibrillation and adhesion. The only highly adherent strain of S. sanguis II carried fimbriae in addition to fibrils. No correlation was observed between cell surface hydrophobicity as measured by phase partitioning with hexadecane and adhesion to S-SHA.
对15株具有周毛状纤丝、纤丝簇或纤丝与菌毛混合物的血链球菌I型菌株和8株血链球菌II型菌株进行了检测，以评估它们在放射性标记试验中黏附于唾液包被的球状羟基磷灰石（S-SHA）的能力。血链球菌I型菌株比血链球菌II型菌株黏附性更好，周毛状纤丝菌株通常比簇状纤丝菌株黏附性更好。纤丝密度与黏附性之间没有相关性。血链球菌II型中唯一一株高黏附性菌株除了有纤丝外还带有菌毛。通过十六烷相分配法测定的细胞表面疏水性与对S-SHA的黏附性之间未观察到相关性。
