The Function and Distribution of Different Fimbriae on Strains of Actinomyces viscosus and Actinomyces naeslundii

Abstract
Actinomyces viscosus and Actinomyces naeslundii differ in their abilities to colonize tooth and epithelial surfaces. These differences appear to be associated with the distribution of different fimbriae on the two species and with the distinct adherence-related functions of these structures.
