What is the advantage to spirochetes of the corkscrew movement provided by axial filaments?
A spirochaete or spirochete is a member of the phylum Spirochaetes (/-ˈkiːtiːz/) which contains distinctive diderm (double-membrane) bacteria most of which have long helically coiled (corkscrew-shaped or spiraled hence the name) cells. Spirochaetes are chemoheterotrophic in nature with lengths between 3 and 500 μm and diameters around 0.09 to at least 3 μm. Spirochaetes are distinguished from other bacterial phyla by the location of their flagella sometimes call…
A spirochete (plural spirochetes ) is a very thin elongate flexible spiral bacteria that is motile via internal periplasmic flagella inside the outer membrane. They comprise the phylum Spirochaetes.Owing to their morphological properties spirochetes are difficult to Gram-stain but may be visualized using dark field microscopy or Warthin–Starry stain.

A flagellum (/ f l ə ˈ dʒ ɛ l əm /; plural: flagella) is a lash-like appendage that protrudes from the cell body of certain cells termed as flagellates.A flagellate can have one or several flagella. The primary function of a flagellum is that of locomotion but it also often functions as a sensory organelle being sensitive to chemicals and temperatures outside the cell.
Treponema pallidum is a spirochaete bacterium with various subspecies that cause the diseases syphilis bejel and yaws.It is transmitted only amongst humans. It is a helically coiled microorganism usually 6–15 μm long and 0.1–0.2 μm wide. T. pallidum's lack of metabolic pathways (tricarboxylic acid cycle oxidative phosphorylation) results in minimal metabolic activity.
Chemotaxis (from chemo-+ taxis) is the movement of an organism in response to a chemical stimulus. Somatic ...
