Abstrakt: The adherence of streptococci to hydroxyapatite spheroids (HAS) depended upon the strain used, the fermentable carbon source available during bacterial growth, the number of times a clinical isolate had been subcultured on laboratory media and the pre-treatment of the HAS. Sucrose greatly stimulated the secondary colonization of Streptococcus mutans strain 3209 on HAS pre-equilibrated with this strain, but no similar effect was observed with glucose. Pre-equilibration of HAS with Streptococcus sanguis 7865 inhibited rather than enhanced subsequent colonization by Strep. mutans strain 3209 in the presence of sucrose.
