Figure 1. Micrographs of the distribution of actinomyces and streptococci on pellicle surfaces for the different sequences of co-adhesion studied. (A) Actinomyces in buffer followed by streptococci in saliva. (B) Streptococci in saliva followed by actinomyces in buffer. (C) Actinomyces in saliva followed by streptococci in saliva. (D) Streptococci in saliva and actinomyces in saliva. Bar marker represents 20 µm.

Figure 2. The percentages of bacteria adhering as single bacteria or in multiplets (> 10 bacteria) for the different sequences of co-adhesion. Note that intermediate multiplets have not been indicated. Actinomyces in buffer followed by streptococci in saliva (white); actinomyces in saliva followed by streptococci in saliva (striped); streptococci in saliva followed by actinomyces in buffer (dotted); and streptococci in saliva followed by actinomyces in saliva (black). Bars indicate SD over 36 experiments, carried out with separately grown bacteria and different pellicle surfaces.
