Outline of Final Research Achievements

We evaluated the pathogenicity of 120-kDa collagen-binding proteins (CBP) of Streptococcus mutans for systemic disease development. CBP-positive S. mutans organisms in the oral cavity were found to be involved in development of cardiovascular diseases, including infective endocarditis and cerebral microbleeds, as well as IgA nephropathy, classified as a designated intractable disease. As a novel approach for inhibition of S. mutans, fruit-derived components exhibited inhibitory effects on both bacterial growth and biofilm formation activities.

Academic Significance and Societal Importance of the Research Achievements

本研究結果から、口腔内に存在するCBP 陽性のS. mutansがう蝕だけでなく様々な全身疾患の増悪化に関わることが明らかになり、口腔衛生状態を良好に保ちう蝕の予防に努めることが、全身疾患の予防にも有効である可能性を示すことができた。また、ある種の食品を応用することにより、S. mutansによるう蝕や全身疾患を低減できる可能性を示すことができた。
