Eubacterium
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.
Gram-positive bacteria have a thick proteoglycan layer and take up violet Gram stain. Species from this genus have been isolated from women with bacterial vaginosis.
