Fine‐tuned production of hydrogen peroxide promotes biofilm formation of <i>Streptococcus parasanguinis</i> by a pathogenic cohabitant <i>Aggregatibacter actinomycetemcomitans</i>

Abstract excerpt

Summary Balanced bacterial biofilm communities help to maintain host health. Disturbance of such balance can lead to bacterial dysbiosis and pathogenesis. However, complex and dynamic bacterial interactions within the biofilm communities are poorly understood. In this study, we used a dual‐species biofilm consisting of the periodontal pathogen Aggregatibacter actinomycetemcomitans , and a commensal Streptococcus...
