Notes:
- 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
- 😷 The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — 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 4 times in PubMed until 2026-06-11.
- 🧍 Although the number DSM 9535 appears in the effective publication, no type strain is designated in the paper by Duffaud et al. 1998. However, the strain DSM 9535 does not appear on the DSMZ website and would appear not to be available from the publicly accessible section of that collection. With the kind permission of Professor Robert M. Kelly, Dr. Elena Pikuta deposited the strain SHCK-94 (here designated as the type strain) in the ATCC (ATCC BAA-1085) and the JCM (JCM 12858), and provided documentation confirming deposit in these collections.
