• Notes:
  • 🥇 Nomenclatural type of the genus Atlantibacter Hata et al. 2025. Publication: Hata H, Natori T, Mizuno T, Kanazawa I, Eldesouky I, Hayashi M, Miyata M, Fukunaga H, Ohji S, Hosoyama A, et al.

  • ❗ Atlantibacter hermannii is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Atlantibacter.
  • 😷 The risk group for Belgium has been imported on 2024-02-05. The full classification is: risk group = 2, note = "human pathogen". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🎓 Name mentioned 12 times in PubMed until 2026-02-10.
  • 😴 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself. This name is taxonomically suspended (and therefore not recommended for medical use for now) until no later than 2030 in favour of Escherichia hermannii Brenner et al. 1983.
