• Notes:
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. The usage of the term "coherent taxon" (or equivalent) is cautioned against. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M.

  • 🎓 Name mentioned 3 times in PubMed until 2025-06-04.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the genus.
  • 🧍 According to Rules 27(3) and 30, this name is not validly published because the effective publication only documents deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Actinocorallia aurantiaca (Lavrova and Preobrazhenskaya 1975) Zhang et al. 2001 is to be considered to be validly published.
