• Notes:
  • 🧬 The phylogenomic assignment score of this taxon is 0.16540 (N = 1).
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 2 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 2". — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 2, note = "ht". — 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 species itself.
  • 🧍 According to Rules 27(3) and 30, this name is not validly published because the effective publication only documents deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Streptococcus gallolyticus subsp. pasteurianus (Poyart et al. 2002) Schlegel et al. 2003 is to be considered to be validly published.
