Eubacterium

This article is about the genus Eubacterium. For eubacteria as opposed to archaea (archaebacteria), see Eubacteria.

Eubacterium is a genus of Gram-positive bacteria in the family Eubacteriaceae. These bacteria are characterised by a rigid cell wall. They may either be motile or nonmotile. If motile, they have a flagellum. A typical flagellum consists of a basal body, filament, and hook. The long filament is the organ which helps eubacteria move.^{[citation needed]}
