The hmuR mutant of
P. gingivalis
is deficient in community accumulation. (A) Confocal
microscopy showing x-y and x-z projections of communities of
S. gordonii
(red),
F. nucleatum
(green)
and
P. gingivalis
(blue) wild type (WT) or
hmuR mutant strains. Representative image from three
independent experiments. (B) Confocal microscopy showing x-y and x-z projections of single species
P. gingivalis
WT or

hmuR mutant accumulations. Representative image from three independent
experiments. (C) Biovolume analysis of
P. gingivalis
WT or

hmuR mutant accumulation in the
P.
gingivalis-F. nucleatum-S. gordonii
communities shown in A. (D) Biovolume analysis of
P. gingivalis
WT or
Δ
hmuR
single species accumulations measured by crystal violet staining and release. (F) Biovolume analysis
of
P. gingivalis
WT or

hmuR single species accumulations shown in B. (E) Biomass of
P. gingivalis
WT or

hmuR accumulation in two species
P. gingivalis-S. gordonii
communities.
