Survival of F. nucleatum aggregated and non-aggregated with S. sanguinis within S-mix. A: co-aggregation buffer treated (Fn/Ss) and non-treated (Fn+Ss) F. nucleatum and S. sanguinis SI-101 mixture were co-cultivated with S-mix in a 1:10 ratio in cell numbers. The viability of F. nucleatum (Fn) and S-mix was monitored every 12 hours. The data were expressed as percentage of viable count of F. nucleatum to the total viable count of S-mix. B: Quantitative measurement of H2O2 production. The H2O2 concentration within the co-cultures was monitored every 12 hours. 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).
