• Notes:
  • 📠 This subspecies was automatically created by the valid publication of Yersinia pseudotuberculosis subsp. pestis (Lehmann and Neumann 1896) Bercovier et al. 1981 according to rule 40d. Publication: Bercovier H, Mollaret HH, Alonso JM, Brault J, Fanning GR, Steigerwalt AG, Brenner DJ. Intra- and interspecies relatedness of Yersinia pestis by DNA hybridization and its relationship to Yersinia pseudotuberculosis. Curr. Microbiol. 1980; 4:225-229.
  • ❗ Yersinia pseudotuberculosis subsp. pseudotuberculosis is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Yersinia pseudotuberculosis within a separate genus Yersinia.
  • 😷 The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 2.

  • 🧍 The original authorship, (Pfeiffer 1889) Smith and Thal 1965, was corrected according to the new Rule 40d. Publication: Garrity GM, Labeda DP, Oren A. Judicial Commission of the International Committee on Systematics of Prokaryotes. XIIth International (IUMS) Congress of Bacteriology and Applied Microbiology.

  • 🧍 The subspecies name Yersinia pseudotuberculosis subsp. pestis (Lehmann and Neumann 1896) Bercovier et al. 1981 is placed on the list of nomina rejicienda because of practical concerns about human welfare. Therefore, Yersinia pseudotuberculosis subsp. pseudotuberculosis (Pfeiffer 1889) Bercovier et al. 1981 should thereafter be designated simply as Yersinia pseudotuberculosis (Pfeiffer 1889) Smith and Thal 1965 (Approved Lists 1980).
