Figure 4

Localization of P. gingivalis, F. nucleatum and T. denticola within the biofilms. IF staining was performed for T. denticola (cyan), F. nucleatum (red) and YoPro-1 iodide & Sytox Green mixture for all other bacteria (green). Groups are defined by the use of the corresponding P. gingivalis strain (W50; wild-type, E8; Arg-gingipain-deficient mutant, K1A; Lys-gingipain-deficient mutant) in the biofilm. Scale bar length: 20 μm.
