The Vibrionaceae are a family of Proteobacteria, given their own order. Several species are pathogenic, including the type species Vibrio cholerae, which is the agent responsible for cholera. Others are found in freshwater and marine habitats. Of particular note, most luminescent bacteria belong to this family, and are typically found as symbiotes of deep-sea animals.
The Vibrionaceae have Gram-negative stains, and are facultative anaerobes capable of fermentation. They contain oxidase and have multiple flagella, which are generally polar although this varies. Originally these characters defined the family, which was divided into four genera. Two of these, Vibrio and Photobacterium, correspond to the modern group, although several new genera have been defined. Genetic studies have shown the other two, Aeromonas and Plesiomonas, belong to separate families.
