Porphyromonas gingivalis integration in dual-species biofilms with Fusobacterium nucleatum ATCC 23726 ΔFap2, ΔRadD and ΔFap2/ΔRadD outer membrane proteins mutant derivatives. Biofilm integration is given as a percentage relative to biofilm integration measured with WT F. nucleatum ATCC 23726. At least three independent experiments were performed per strain combination. Data represent the means and standard deviation of at least three independent experiments. *P<0.05; **P<0.01; ##P<0.01. WT, wild type.
