Related to Spirochaeta: Spirochaeta pallida


A genus of motile bacteria (order Spirochaetales) containing presumably gram-negative, flexible, undulating, spiral-shaped rods that may or may not possess flagelliform, tapering ends. The protoplast is spirally wound around an axial filament. No obvious periplast membrane or cross-striations occur. These organisms are motile by means of a creeping motion over the surfaces of supporting objects. They are not parasitic but are found free living in fresh or sea water slime; they are commonly found in sewage and foul water. At present the genus contains five species. The type species is Spirochaeta plicatilis.
