  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1". — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 2, note = "t". — The risk group for Taiwan has been imported on 2024-11-03. The full classification is: risk group = 1, note = "P650 = v". — 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 88 times in PubMed until 2026-06-11.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 The separation of Porphyromonas gulae and Porphyromonas gingivalis into distinct species was confirmed by the 16S-23S rRNA gene internal transcribed spacer (ITS) data.
