Endoflagella
Endoflagella (pronunciation: en-doh-fla-jell-uh) is a term used in the field of Microbiology to describe a type of Flagella found in certain Bacteria.
Etymology
The term "Endoflagella" is derived from the Greek words "endo", meaning within, and "flagella", meaning whip. This is in reference to the whip-like structure of the endoflagella that is located within the periplasmic space of the bacteria.
Description
Endoflagella, also known as Periplasmic flagella, are unique structures that differentiate certain bacteria, such as Spirochetes, from others. Unlike external flagella, endoflagella are located in the periplasmic space of the bacteria, between the outer membrane and the cell wall. They are responsible for the distinctive corkscrew-like motion of these bacteria.
Function
The primary function of endoflagella is to provide motility to the bacteria. They rotate within the periplasmic space, causing the entire bacterium to move in a twisting or spiraling motion. This unique form of movement allows the bacteria to move in viscous environments, such as mucus or tissue.

- Periplasmic space: The space between the outer membrane and the cell wall in Gram-negative bacteria, where endoflagella are located.
