• Notes:
  • 🎓 Name mentioned 1 time 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 other species in the genus.
  • 🧍 The IJSEM Notification List in which this name appears list states that this name is not validly published because the authors based it on a basonym that was not validly published at that time. According to Rule 27 Note 1 of the International Code of Nomenclatur of Prokaryotes (ICNP) an IJSEM Notification List “has no formal status in prokaryote nomenclature except to allow for orthographic corrections to be made”, i.e. an IJSEM Notification List is not decisive about whether or not a name is validly published. While the basonym used by the authors of the effective publication was indeed not validly published at that time, no Rule of the ICNP was cited that provides evidence that another name is not validly published when allegedly based on such a basonym. LPSN interprets this name as not being a new combination but currently sees no reason for regarding the name as not being validly published. For instance, while Rule 27 (2a) stipulates that a new name or new combination must be indicated as such it does not specify what happens if this is done incorrectly (as opposed to not being done at all).
