Figure 2. In Panel A, the green wireframe denotes bacteria labeled by the P. gingivalis-specific probe. There were many bacterial masses within the cell shown, but only small portions of those masses appeared to contain P. gingivalis. In Panel B, the green wireframe indicates bacteria labeled by the T. forsythensis-specific probe. Note that the upper perimeter of that cell could not be properly rendered. The cell seemed to be almost completely filled with bacteria. Large masses of T. forsythensis were present, but species recognized only by the universal probe appeared to dominate the intracellular flora (the scale bar in Panel B applies to Panel A as well).
