Motility behavior of the vibrioid bacteria. (A) Schematic drawing of the bipolar flagellated bacterium indicating the translation (T) and rotation axis (R) of its motility. The angle between both axes is denoted as β. (B) Two-dimensional projections of successive positions of the bacterium along its swimming path if the axes T and R are aligned (β = 0). The center of the cell follows a straight line, whereas both ends describe a helical pathway. (C) As described for B but the axes T and R are slightly diverging (β = 0), and the center of the cell follows a helical pathway.
