Butyrivibrio is a genus of bacteria in Class Clostridia. Bacteria of this genus are common in the gastrointestinal systems of many animals. Genus Butyrivibrio was first described by Bryant and Small (1956) as anaerobic butyric acid-producing curved rods (or vibroids). Butyrivibrio cells are small typically 0.4 – 0.6 µm by 2 – 5 µm. They are motile using a single polar or subpolar monotrichous flagellum.
