Notes:
- 🎓 Name mentioned 1 time in PubMed until 2025-10-21.
- 🙆 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.
- 🧍 Originally considered not validly published. "The MTA from the US National Parks Authority attached to the type strain is not acceptable for type strains as it is considered to contravene Rule 30(4) of the ICNP." However, a careful reexamination of this MTA revealed that there are distinct MTAs associated with US National Parks and that the one in question is not in conflict with the requirements for valid publication. — Oren A. Personal communication, 2020-11-15.
