  • 🥇 Nomenclatural type of the genus Ruania Gu et al. 2007. Publication: Gu Q, Pasciak M, Luo H, Gamian A, Liu Z, Huang Y. Ruania albidiflava gen. nov., sp. nov., a novel member of the suborder Micrococcineae. Int J Syst Evol Microbiol 2007; 57:809-814. 🇨🇳
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281. 🇬🇧
  • 😷 The risk group for Germany has been imported on 2023-10-29. 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.
