• Notes:
  • ❗ Propionibacterium freudenreichii subsp. freudenreichii 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 Propionibacterium freudenreichii within a separate genus Propionibacterium.
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — 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. — 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 the name to be applied to this subspecies. The name is on LoRN because of the recorded risk group of the genus.
  • 🧍 In the Approved Lists of Bacterial Names, Propionibacterium freudenreichii subsp. freudenreichii is erroneously cited as Propionibacterium freudenreichii subsp. freudenreichii (van Niel 1928) Moore and Holdeman 1970 (Opinion 86).
