This study examines how oxygen levels affect the structure and composition of a four-species oral biofilm model over 21 days, finding that the community remains resilient and dominated by Veillonella dispar across all oxygen conditions.

The paper develops a human intestinal organoid co-culture model with macrophages to study bacterial infection control, finding that activated macrophages reduce bacterial burden and cytotoxicity.
