• Notes:
  • 🎓 Name mentioned 0 times in PubMed until 2025-06-04.
  • 🙅 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 genus.
  • 🧍 Canale-Parola requested that Spirochaeta stenostrepta replace Spirochaeta plicatilis as the type species of the genus Spirochaeta, because no culture of Spirochaeta plicatilis exists. Rule 18a of the Bacteriological Code (1990 Revision) does permit a description to serve in place of a type culture. Therefore the Judicial Commission voted to deny the action proposed.
