Bacterial flagellumPeriplasmic flagellum


Spirochetes have a flagellum that resides inside the cell within the periplasmic space. The number of flagella varies from species to species. The rotation of these structures results in specific movements of the cell body, which in turn enable the locomotion of the cell. In particular they impart spirochetes the ability to propel themselves through viscous media that would inhibit the rotation of external flagellar filaments.
