Spirochaeta

Spirochaeta
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 waters. At present the genus contains five species. The type species is S. plicatilis. [Mod. L. fr. G. speira, a coil, + chaite, hair]
- S. obermeieri SYN: Borrelia recurrentis.
- S. plicatilis a very large species (sometimes as long as 200 μm) of bacteria; it is nonparasitic, so far as known; it is the type species of the genus S..
