Campylobacterota are a phylum of

Gram-negative bacteria.[3] Only a few genera have been characterized, including the curved to spirilloid Wolinella, Helicobacter, and Campylobacter. Until the 2021 revision of bacterial taxonomy by the ICSP,[4] the entire phylum was classified within the Proteobacteria (synonym Pseudomonadota) as the Epsilonproteobacteria.[5]

Most of the known species inhabit the digestive tracts of animals and serve as

Many Campylobacterota are motile with flagella.[11] The Campylobacterota found at deep-sea hydrothermal vents characteristically exhibit chemolithotrophy, meeting their energy needs by oxidizing reduced sulfur, formate, or hydrogen coupled to the reduction of nitrate or oxygen.[12] Autotrophic Campylobacterota use the reverse Krebs cycle to fix carbon dioxide into biomass, a pathway originally thought to be of little environmental significance. The oxygen sensitivity of this pathway is consistent with their microaerophilic or anaerobic niche in these environments, and their likely evolution in the Mesoproterozoic oceans,[13] which are thought to have been sulfidic with low levels of oxygen available from cyanobacterial photosynthesis.[14]
