• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Arcobacter Vandamme et al. 1991. Publication: Dieguez AL, Balboa S, Magnesen T, Romalde JL. Arcobacter lekithochrous sp. nov., isolated from a molluscan hatchery. Int J Syst Evol Microbiol 2017; 67:1327-1332.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Pseidonibacter".
  • 🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: On SLW. International Committee on Systematics of Prokaryotes (ICSP) Subcommittee on the Taxonomy of Campylobacter and related bacteria: minutes of the closed meetings, 17 January and 31 January 2024. Int J Syst Evol Microbiol 2025; 75:6618.
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Perez-Cataluna et al. (2018). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • ❗ Poseidonibacter is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: MCCC: 1; KACC: 1; KCTC: 1; CECT: 1; JCM: 1; DSM: 1.
  • 🧍 The dissection of Arcobacter was opposed by On et al. (2020). Publication: On SLW, Miller WG, Biggs PJ, Cornelius AJ, Vandamme P. A critical rebuttal of the proposed division of the genus Arcobacter into six genera using comparative genomic, phylogenetic, and phenotypic criteria. Syst Appl Microbiol 2020; 43:126108.
