• Notes:
  • 📠 This subspecies was automatically created by the valid publication of Fusobacterium necrophorum subsp. funduliforme (ex Hallé 1898) Shinjo et al. 1991 according to rule 40d. Publication: Shinjo T, Fujisawa T, Mitsuoka T. Proposal of two subspecies of Fusobacterium necrophorum (Flugge) Moore and Holdeman: Fusobacterium necrophorum subsp. necrophorum subsp. nov., nom. rev. (ex Flugge 1886), and Fusobacterium necrophorum subsp. funduliforme subsp. nov., nom. rev. (ex Halle 1898). Int J Syst Bacteriol 1991; 41:395-397.
  • ❗ Fusobacterium necrophorum subsp. necrophorum 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 Fusobacterium necrophorum within a separate genus Fusobacterium.
