FIG. 2.

Total number of planktonic cells eroding from biofilm cultures over 4-h time intervals of cultures of Phillips cells grown on collagen at a wall shear rate of 40 s⁻¹ (black bars), Phillips cells grown on collagen at 100 s⁻¹ (gray bars), Phillips cells grown on fibrinogen at 100 s⁻¹ (stippled bars), and PH100 cells grown on fibrinogen at 100 s⁻¹ (diagonally striped bars). An asterisk indicates statistical significance with respect to the culture grown at 40 s⁻¹ (P < 0.05). Data represent means ± standard deviations of three or more experiments.
