Notes:
- 😷 The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
- 🎓 Name mentioned 1 time in PubMed until 2026-06-11.
- 🙆 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.
- 🧍 May not be validly published. The deposit number in one of the two culture collections in which the type strain was supposed to be deposited is unknown. — Gronow S. Personal communication, 2021-02-26.
- 🧍 The type strain is also available from the culture collections of the WHO Collaborating Centres in Amsterdam, The Netherlands, and Brisbane, Australia. — Leibniz Institute DSMZ. Prokaryotic Nomenclature Up-to-date, 2018-12-11.
