구강 Streptococci의 Hydroxyapatite 비드에의 부착에 관한 연구 = A STUDY ON THE ADHERENCE OF ORAL STREPTOCOCCI TO HYDROXYAPATITE BEAD

다국어 초록 (Multilingual Abstract)

The adherence of ^3H-labeled Streptococcus mutans 10449 cells to spheroidal hydroxyapatite(HA) beads was studied. The adherence equilibrium occured within 2 hrs. The number of cells adhering to SHA was 50% less than those on HA bead. When the assay was performed with non-heated saliva at different temperatures, 20% more cells were found to adhere to SHA at room temperature than at 4℃. This indicates the release of labeled DNA from bacterial cells possibly lyzed by lysozyme at the higher temperature. It was observed that saliva from different subjects had varing effect on bacterial adherence to HA. Use of saliva adsorbed with homologous bacteria decreased S. mutans adherence by 38%, indicating the presence of salivary agglutinin in aquired pellicle formed on HA. The desorption experiment of adhered bacteria confirmed the previous reports that the adhesive sites on HA bead for S. mutans were different from those for S. sanguis and that S. mutans could enhance the adherence of S. sanguis but not vice versa.
