2 The subspecies name Yersinia pseudotuberculosis subsp. pseudotuberculosis (Pfeiffer 1889) Bercovier et al. 1981 is automatically created by the valid publication of Yersinia pseudotuberculosis subsp. pestis (Lehmann and Neumann 1896) Bercovier et al. 1981 [Rule 40d (formerly Rule 46)].

¤ Yersinia pseudotuberculosis (Pfeiffer 1889) Smith and Thal 1965 (Approved Lists 1980).

Note: 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).
