Flagella (singular: flagellum) enable bacteria to swim towards sources of nutrition, and away from sources of toxins. Such directed motility is termed ''[http://en.wikipedia.org/wiki/Chemotaxis chemotaxis]''. Rapid swimming helps [http://en.wikipedia.org/wiki/Bdellovibrio Bdellovibrio] penetrate and parasitize their host bacteria, but flagella are not always essential for virulence<ref name="virulence1">PMID: 2152887</ref>. Flagella are important in responses to quorum sensing<ref name="quorum1">PMID: 15449604</ref> and biofilm formation<ref name="biofilms1">PMID: 19231189</ref><ref name="biofilms2">PMID: 17416647</ref>.

The bacterial flagellum is made up of about 25 different proteins. There are only a few copies of some proteins, and tens of thousands of copies of the filament protein, FliC. The flagellum is made up of three major regions, as follows. | The bacterial flagellum is made up of about 25 different proteins.
