A genus of Gram-negative bacteria which are found in water and cause cholera.
One of the two genera within the family Spirillaceae, and consisting of aerobic Gram-negative curved rods. The organisms possess a characteristic darting motility, and may present an irregular morphology on culture. Vibrio cholerae is the causative organism of Asiatic cholera, and is diagnosed by cultivation on Dieudonne’s medium, specific peptone-water sugar reactions, agglutination by ‘O’ and ‘H’ antisera (the former being specific), production of indole and nitrites from peptone water (cholera-red reaction), Voges – Proskauer and haemolysis tests. Vibrio eltor (the el Tor vibrio), connected with less severe cholera, is a haemolytic biotype of Vibrio cholerae with differing (+) VP and resistance to polymyxin. Paracholera vibrios (from less severe choleraic outbreaks) may show differing biochemical reactions and are distinguished by their ‘O’ antigens. Yet other vibrios may be non-pathogenic, or infectious only to domestic animals.
Genus of comma-shaped bacteria, some members of which produce disease in humans (e.g.. Vibrio cholerae, the agent that causes cholera).
A genus of Gram-negative motile comma-shaped bacteria widely distributed in soil and water. Most species are saprophytic but some are parasites, including V. cholerae, which causes cholera.
A bacterium with a curved shape, such as the vibrio of cholera.
A genus of curved, motile, gram-negative bacilli, several of which may be pathogenic for humans.
