    Notes:
    • 🧍 Roop et al. 1986 propose a neotype strain because the type strain Forsyth ER33 is no longer extant (Rule 18c).
  • On et al. 1998 On SL, Atabay HI, Corry JE, Harrington CS, Vandamme P.

    Notes:
    • 🧍 On et al. 1998 [1] propose that the infrasubspecific divisions of Campylobacter sputorum should be revised to include biovar Sputorum for catalase- and urease-negative strains; biovar Faecalis corrig. for catalase-positive and urease-negative strains; and biovar Paraureolyticus, bv. nov., for catalase-negative and urease-positive strains [suitable reference strains: LMG 11764 (human isolate) and LMG 17590 = CCUG 37579 (bovine isolate)]. The Subcommittee on the taxonomy of Campylobacter and related bacteria [2] agreed to endorse this revised biovar nomenclature and to correct the spelling of the biovar name Fecalis (sic) to Faecalis.
