  • 🙆 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 genus.

  • 🧍 Practically all characteristics of three strains (including the type strain) of Staphylococcus pulvereri Zakrzewska-Czerwińska et al. 1995 are in conformity with those described for the species Staphylococcus vitulinus corrig. Webster et al. 1994. The author supposes that these strains actually belong to the species Staphylococcus vitulinus. Publication: Petras P. Staphylococcus pulvereri = Staphylococcus vitulus? Int J Syst Bacteriol 1998; 48:617-618.
  • 🧍 The original spelling of the specific epithet, vitulus (sic), has been corrected by Trüper and De' Clari 1998. Publication: Trüper HG, De' Clari L.

  • 🧍 The ribotypes of Staphylococcus vitulinus strains were either similar or identical to those of strains Staphylococcus pulvereri. This observation suggests strongly that they belong to the same species. It is nevertheless, possible that they are different subspecies. — 🧍 The synonymy between Staphylococcus vitulinus and Staphylococcus pulvereri is supported by the Subcommittee on the taxonomy of staphylococci and streptococci.
