• Notes:
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 2, 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 Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1, note = "PIIC". — 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 species itself.
  • 🧍 Listed as urealyticum in the notification list. Publication: Anonymous. Notification list. Notification that new names and new combinations have appeared in volume 41, part 2 of the IJSB. Int J Syst Bacteriol 1991; 41:581.
  • 🧍 Illegitimate according to the ICNP (contravening Rules 12b and 13c). The subspecific epithet urealyticus in Staphylococcus cohnii subsp. urealyticus corrig. Kloos and Wolfshohl 1991 is a later homonym of the subspecific epithet urealyticus in Staphylococcus capitis subsp. urealyticus corrig. Bannerman and Kloos 1991. Because no two subspecies within a genus may bear the same subspecific epithet (Rules 12b and 13c), urealyticus in the name Staphylococcus cohnii subsp. urealyticus corrig. will have to be replaced. — 🧍 The original spelling, Staphylococcus cohnii subsp. urealyticum (sic), has been corrected by Sneath 1992. Publication: Sneath PH. Correction of orthography of epithets in Pasteurella and some problems with recommendations on latinization. Int J Syst Bacteriol 1992; 42:658-659.
