How does bacteria move?

    There are three ways in which bacteria move:
    -The use of flagella which protrude from the cell and can work like a tail(s)
    -Some bacteria such as Spirochaetes have what is known as an axial filament which is an internalized structure which allows the cell to rotate in a spiral-like manner, resulting in locomotion.
    -Gliding bacteria secrete a copious slime, but the mechanism which allows mobility is still unknown.

    Most forms of bacteria move through the use of flagella. These things are long, whip-like tails that allow bacteria to swim through their environment. The flagella serves the same function of a ship’s propeller for bacteria. Other forms of bacteria control their depth in water through the use of gas bubbles, while some just glide through surfaces, leaving trails of slime.

    To follow up on these answers, which are both correct.  There are some semi-understood way that bacteria move by bacterial gliding.  After secretion, some bacteria glide using type IV Pili, which is a system made of several thin, but strong pilin (protein strings) for movement.  Other bacteria that move by bacterial gliding use a twitching energy that is not understood.
