<i>Corynebacterium matruchotii</i> Demography and Adhesion Determinants in the Oral Cavity of Healthy Individuals
<i>Corynebacterium matruchotii</i> may be key in tooth biofilm formation, but information about demographics, bacterial partners, and binding ligands is limited. The aims of this study were to explore <i>C. matruchotii</i>’s demography by age and colonization site (plaque and...
