Survival of F. nucleatum in aggregates with S. sanguinis and non-aggregated cells. The two chamber assay in which aggregated (Fn/Ss) and non-aggregated (Fn+Ss) F. nucleatum and S. sanguinis cells were added to the upper chamber, while F. nucleatum cells alone were co-cultured with O-mix in the lower chamber. Samples in the upper chamber were taken periodically to monitor F. nucleatum viability. Two independent experiments were performed in three replicates each, and average values ± SD are shown. The asterisk indicates significant differences between two values (Student’s T-test P value < 0.05).
