• Notes:
  • ❗ Streptococcus lactis subsp. diacetilactis is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Streptococcus lactis within a separate genus Streptococcus.
  • 😷 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 2023-10-29. 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.
  • 🙅 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 subspecies. The name is on LoRN because of the recorded risk group of the genus.
