ABSTRACT:
Polypeptides related to fimbriae of Porphyromonas gingivalis are described and claimed which exhibit inhibition of bacterial adhesion to saliva-coated surfaces. The polypeptides are selected from the group consisting of fimbriae, fimbrillin, and fimbrial-related. peptides derived therefrom. The polypeptides are used as active ingredients in various oral formulations designed to prevent adhesion of P. gingivalis to host mucosal surfaces and thus interfering with the development of periodontitis. The polypeptides are also used in subunit vaccine formulations for use against pathogenic, fimbriated P. gingivalis in the prophylactic treatment of periodontitis. Use of the polypeptides for inducing protective immunity in serum and gingival crevicular fluid may prevent primary infection with P. gingivalis as well as the spread of the organism between intraoral reservoirs.
