Survival of P. gingivalis strains in a serum environment. a Graphs showing coverage of P. gingivalis strains 33F, W50 and SUB1 on surfaces in the presence (filled square) or absence (open square) of a serum coating. The bars show the mean ± SD of three independent biological replicates. Representative images show adherent bacteria stained with Baclight Live/Dead stain. The bar represents 10 µm. **p < 0.01. b Growth of P. gingivalis strains 33F (filled triangle), W50 (open circle) and SUB1 (filled diamond) in serum, assessed as absorbance at 600 nm. c Graph showing proteolytic activity of P. gingivalis strains W50 (open circle), K1A (open triangle) or E8 (filled circle) in serum. The graph shows mean ± SD of three independent biological replicates
