P.a. motility is required for blanketing. (A and C) Three-dimensional views of a P.a.-pilA (A) and P.a.-flgK (C) pure-culture biofilms. (B and D) x–y slices close to the attachment surface and 3D views of a P.a.-pilA/A.t. (B) and P.a.-flgK/A.t. (D) Coculture biofilms. Red cells, P.a.; green cells, A.t. (Scale bars, 20 μm; 1 unit in 3D view, 13.4 μm.) All micrographs were taken at 164 h. (E) comstat determination of the relative amount of A.t. biofilm biomass present in cocultures. (F) A quantitative determination of biomass distributions along biofilm depth in P.a.-pilA/A.t. and P.a.-flgK/A.t. coculture biofilms at 96 h.
