| Vibrio
A member of the genus Vibrio, a genus of motile (occasionally nonmotile), nonsporeforming, aerobic to facultatively anaerobic, gram-negative bacteria (family Spirillaceae) containing short (0.5–3.0 mcm), curved or straight rods that occur singly or which are occasionally united into S-shapes or spirals. Motile cells contain a single polar flagellum; in some species, two or more flagella occur in one polar tuft. Some of these organisms are saprophytes in salt and fresh water and in soil; others are parasites or pathogens. | |
