<i><scp>P</scp>orphyromonas gingivalis</i> displays a competitive advantage over <i><scp>A</scp>ggregatibacter actinomycetemcomitans</i> in co‐cultured biofilm

Abstract

These results suggest that P. gingivalis possesses a competitive advantage over A. actinomycetemcomitans. As the required biofilm-formation abilities and proteolytic activities vary among P. gingivalis strains, the diversity of the competitive advantage is likely to affect disease recurrence during periodontal maintenance.
