Movement
Biofilm bacteria can move in numerous ways that allow them to easily infect new tissues. Biofilms may move collectively, by rippling or rolling across the surface, or by detaching in clumps. Sometimes, in a dispersal strategy referred to as “swarming/seeding”, a biofilm colony differentiates to form an outer “wall” of stationary bacteria固定细菌, while the inner region of the biofilm “liquefies液化”, allowing planktonic cells to “swim” out of the biofilm and leave behind a hollow mound.26
