• Notes:
  • 🥇 Nomenclatural type of the genus Kalamiella Singh et al. 2019. Publication: Singh NK, Wood JM, Mhatre SS, Venkateswaran K.

Appl Microbiol Biotechnol 2019; 103:6851-6852. 🇺🇸
  • ❗ Kalamiella piersonii is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Kalamiella.
  • 😷 The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 1, note = "+". — 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 15 times in PubMed until 2026-06-11.
  • 🙅 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.
