  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this subspecies. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 According to P.A.R. Vandamme [1], the subspecific epithet venerealis is incorrect. The formation of venerealis is derived from a combination of the Latin adjective venereus and the suffix -alis, used to form an adjective. As, it is grammatically incorrect to combine an adjective-forming suffix to a word that is already an adjective, the subspecific epithet should be venereus. However, members of the Subcommittee on the taxonomy of Campylobacter and related bacteria [2] reached a consensus to correct the etymology of the subspecific epithet venerealis. The correct etymology is: ve.ne.re.a'lis. N.L. (arbitrary) adj. venerealis, pertaining to venereal disease. Publication: On SL. International Committee on Systematic Bacteriology Subcommittee on the taxonomy of Campylobacter and related bacteria. Minutes of the meeting, 2 September 1998, Budapest, Hungary. Int J Syst Evol Microbiol 2000; 50:1399-1400.
  • 🧍 Members of the Subcommittee on the taxonomy of Campylobacter and related bacteria had noted that the specific epithet fetus was erroneously formed. This required correction of the spelling of the epithet or, alternatively, correction of the etymology. The subcommittee members reached a consensus to correct the etymology of the specific epithet fetus. The correct etymology is: fe'tus. L. masc. n. fetus, fetus, fruit; L. gen. masc. n. fetus, of a fetus. Publication: Vandamme P, On SL. Recommendations of the subcommittee on the taxonomy of Campylobacter and related bacteria. Int J Syst Evol Microbiol 2001; 51:719-721.
  • 🧍 On the Approved Lists of Bacterial Names and on the Approved Lists of Bacterial Names (Amended Edition), the type strain is erroneously cited as ATCC 19483. — Tang J. Personal communication, 2001-04-05.
