  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this subspecies. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 According to Yarza et al. (2013), an "orphan species with designated type strains that were either not deposited in culture collections or whose type strain is currently not available from a recognized culture collection".
