Abstract
A purified oligosaccharide consisting of a hexasaccharide with a native molecular weight of 959 which can be isolated from the cell walls of Streptococcus oralis. The oligosaccharide is able to significantly block the interaction between the human oral plaque bacteria Streptococcus oralis H1 and Capnocytophaga ochracea ATCC 33596. This purified oligosaccharide contains saccharide components found to inhibit many know interactions between plaque bacteria and may be effective in prevention, inhibition and reversal of dental plaque deposits. The oligosaccharide may be applied effectively when incorporated in toothpastes, mouth wash, etc.
