Flagella of bacteria

WebBacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments. At the base of each flagellum, a reversible rotary motor, which is powered by the proton- or the sodium-motive force, is embedded in the cell envelope. ... WebEvolution of flagella.

WebNov 16, 2011 · We report the switching behavior of the full bacterial flagellum system that includes the filament and the motor in wild-type Escherichia coli cells. In sorting the motor behavior by the clockwise bias, we find that the distributions of the clockwise (CW) and counterclockwise (CCW) intervals are either exponential or nonexponential with long tails. Protozoa are a heterogeneous group with three different locomotion organs: flagella, cilia, and pseudopods. Certain protozoa, such as Leishmania and Trypanosoma, have flagellated forms called promastigotes and non-flagellated forms called amastigotes.
