Spirochaetales

 [spi″ro-ke-ta´lēz]
the spirochetes, an order of bacteria in which some species are free-living and some parasitic; it includes the disease-causing genera Borrelia, Leptospira, and Treponema.

Spi·ro·chae·ta·les

(spī'rō-kē-tā'lēz),
An order of bacteria containing slender, flexuous cells, 6-500 mcm in length, in the form of spirals with at least one complete turn. Some species may have an axial filament, a lateral crista, or ridge, or transverse striations. All these organisms are motile, whirling or spinning about the long axis, thus driving the organism forward or backward. Free-living, saprophytic, and parasitic forms occur. The type family is Spirochaetaceae.
