[The adhesive properties and surface characteristics of streptococci colonizing buccal epithelial cells].

The species spectrum of streptococci subjected to desorption has been found to differ from that of streptococci tightly adhering to epithelial cells, the former streptococci having more hydrophilic surface than the latter ones. No difference in their electrophoretic mobility has been detected. The study of the adhesive properties of the isolated strains has revealed that streptococci with the hydrophilic surface, subjected to desorption in the process of cell washing, less actively adhere to cells of the buccal epithelium.
