  • Title: Salivary protein interactions with oral bacteria: an electrophoretic study.
    Author: Newman F, Beeley JA, MacFarlane TW, Galbraith J, Buchanan L.
    Journal: Electrophoresis; 1993 Dec; 14(12):1322-7. PubMed ID: 8137797.
    Abstract:
    The relatively low levels of human salivary proteins in whole saliva as compared to the ductal secretions may be related to their interaction with oral bacteria. These interactions are thought to play an important role in the microbial colonisation of the mouth, and salivary proteins adsorbed to oral surfaces have been implicated in adherence. In this study we attempted to investigate the prevalence of interactive strains by screening a range of oral bacteria. Parotid saliva was incubated with bacterial suspensions and consequent alterations to the salivary protein profile determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). A number of salivary components were found to be preferentially removed, particularly by those species known to be primary colonizers of clean tooth surfaces.
