Valid publication: Madhaiyan M, Wirth JS, Saravanan VS. Phylogenomic analyses of the Staphylococcaceae family suggest the reclassification of five species within the genus Staphylococcus as heterotypic synonyms, the promotion of five subspecies to novel species, the taxonomic reassignment of five Staphylococcus species to Mammaliicoccus gen. nov., and the formal assignment of Nosocomiicoccus to the family Staphylococcaceae.

Name	Kind

Notes:
- 😷 The risk group for Germany has been imported on 2026-08-13. 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.
- 🎓 Name mentioned 8 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.
- 🧍 Illegitimate according to the ICNP (contravening Rules 12b and 13c). The subspecific epithet ureilyticus in Staphylococcus ureilyticus (Kloos and Wolfshohl 1991) Madhaiyan et al. 2020 repeats the subspecific epithet urealyticus in Staphylococcus capitis subsp. urealyticus corrig. Bannerman and Kloos 1991. The conducted orthographic corrections of the connecting vowel, whether justified or not, did not create a new epithet but only another spelling of the same epithet. Because no two subspecies within a genus may bear the same subspecific epithet (Rules 12b and 13c), ureilyticus in the name Staphylococcus ureilyticus will have to be replaced.
