Motile bacteria move through the function of flagella. These appendages rotate, which propels an organism forwards. This is a little like the propellers on a boat. Some bacteria have one flagellum, others have many, and some possess none at all. Some of the bacteria regarded as human pathogens have flagella. An example of a flagellate bacterium is the ulcer-causing Helicobacter pylori, which uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium. Some flagella also serve a function in environmental detection, sensing different conditions and signalling to a bacterium to move to or away from a given niche.
