Campylobacteraceae Vandamme and De Ley 1991
General information
Description and emendation
Curved, S-shaped, or spiral rods that are 0.2 to 0.9 μm wide and 0.5 to 5 μm long. Gram negative. Nonsporeforming. Cells in old cultures may form spherical or coccoid bodies. Motile by means of a single polar unsheathed flagellum at one or both ends of the cell. Microaerophilic with a respiratory type of metabolism. Some strains may grow under aerobic or anaerobic conditions. Fumarate is reduced to succinate. Optimum temperature, 30 to 37°C. Colonies are usually nonpigmented. All species have oxidase activity. Negative reactions in methyl red and Voges-Proskauer tests, and no production of indole. Nonhemolytic. Gelatin is not liquified. Most species reduce nitrate and do not hydrolyze hippurate. Menaquinones are the sole respiratory quinones. Chemoorganotrophic. A variety of organic acids, including amino acids, are used as carbon sources. Carbohydrates are neither oxidized nor fermented. The DNA base composition ranges from 28 to 46 mol%. Nearly all family members occur in human or animal hosts or in both, often in association with disease. Some strains are considered true pathogens.
