Different Type 1 Fimbrial Genes and Tropisms of Commensal and Potentially Pathogenic Actinomyces spp. with Different Salivary Acidic Proline-Rich Protein and Statherin Ligand Specificities

Abstract excerpt

Actinomyces spp. exhibit type 1 fimbria-mediated adhesion to salivary acidic proline-rich proteins (PRPs) and statherin ligands. Actinomyces spp. with different animal and tissue origins belong to three major adhesion types as relates to ligand specificity and type 1 fimbria genes. (i) In preferential acidic-PRP binding, strains of Actinomyces naeslundii genospecies 1 and 2 from human and monkey mouths displayed...
