  • 🧍 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. — 🧍 The original authorship, (Jones et al. 1931) Véron and Chatelain 1973, was corrected according to the new Rule 40d. Publication: Vandamme P, On SL.
