Quantitative coaggregation assay between Fusobacterium nucleatum ATCC 23726 and mutant derivatives in outer membrane proteins with Porphyromonas gingivalis strains. (a) P. gingivalis 4612 with F. nucleatum ATCC 23726; (b) P. gingivalis T22 with F. nucleatum ATCC 23726; (c) P. gingivalis ATCC 33277 with F. nucleatum ATCC 23726. Data are expressed as relative percentage coaggregation compared with coaggregation reaction of the wild type with the respective P. gingivalis partner strains set as 100%. Data represent the means and standard deviation of at least three independent experiments. *P<0.05; **P<0.01. WT, wild type.
