Vibrio is a genus of Gram-negative bacteria, possessing a curved-rod (comma) shape,^[1][2][3][4] several species of which can cause foodborne infection or soft-tissue infection called Vibriosis. Infection is commonly associated with eating undercooked seafood. Being highly salt tolerant and unable to survive in freshwater, Vibrio spp. are commonly found in various salt water environments. Vibrio spp. are facultative anaerobes that test positive for oxidase and do not form spores.^[4][5] All members of the genus are motile. They are able to have polar or lateral flagellum with or without sheaths.^[4][6] Vibrio species typically possess two chromosomes, which is unusual for bacteria.^[7][8] Each chromosome has a distinct and independent origin of replication,^[9] and are conserved together over time in the genus.^[10] Recent phylogenies have been constructed based on a suite of genes (multilocus sequence analysis).^[1]

O. F. Müller (1773, 1786) described eight species of the genus Vibrio (included in Infusoria), three of which were spirilliforms.^[11] Some of the other species are today assigned to eukaryote taxa, e.g., to the euglenoid Peranema or to the diatom Bacillaria. However, Vibrio Müller, 1773 became regarded as the name of a zoological genus, and the name of the bacterial genus became Vibrio Pacini, 1854.^[12] Filippo Pacini isolated micro-organisms he called "vibrions" from cholera patients in 1854, because of their motility.^[13] In Latin "vibrio" means "to quiver".^[14]
