Twitching motility is a form of crawling bacterial motility used to move over surfaces. Twitching is mediated by the activity of hair-like filaments called type IV pili which extend from the cell's exterior, bind to surrounding solid substrates and retract, pulling the cell forwards in a manner similar to the action of a … See more Pilus structure The type IV pilus complex consists of both the pilus itself and the machinery required for its construction and motor activity.
