• Notes:
  • This subspecies was automatically created by the valid publication of Campylobacter jejuni subsp. doylei Steele and Owen 1988 according to rule 40d. Publication: Steele TW, Owen RJ. Campylobacter jejuni subsp. doylei subsp. nov., a subspecies of nitrate-negative campylobacters isolated from human clinical specimens. Int. J. Syst. Bacteriol. 1988; 38:316-318.
  • The original authorship, (Jones et al. 1931) Veron and Chatelain 1973, was corrected according to the new Rule 40d. Publication: Parker CT, Tindall BJ, Garrity GM. International Code of Nomenclature of Prokaryotes. Int J Syst Evol Microbiol 2019; 69:S1-S111.
  • Members of the Subcommittee on the taxonomy of Campylobacter and related bacteria had noted that the specific and the subspecific epithets jejuni were erroneously formed. This required correction of the spelling of the epithets or, alternatively, correction of the etymology. The subcommittee members reached a consensus to correct the etymology of the specific and of the subspecific epithets jejuni. The correct etymology is: je.ju'ni. N.L. gen. neut. n. jejuni, of the jejunum. Publication: Vandamme P, On SL. Recommendations of the subcommittee on the taxonomy of Campylobacter and related bacteria.
