Spirochaeta

(spī'rō-kē'tă),

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.

gigas (CS3) did not branch into this cluster, but grouped together with the spirochete isolate Spirochaeta aurantia (M57740) as well as a DNA sequence retrieved from the sediments of an Australian fish farm (AY499871).

Collectively, all identified spirochete clones fell into 2 families: the Spirochaetaceae with 2 genera, Cristispira and Spirochaeta, and the Brachyspiraceae, with the genus Brachyspira (Paster & Dewhirst 2000, Leschine et al.
