  • 🙆 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.
  • 🧍 The genome of the type strain was sequenced as part of the GEBA (Genomic Encyclopedia of Bacteria and Archaea) project. Publication: Mukherjee S, Seshadri R, Varghese NJ, Eloe-Fadrosh EA, Meier-Kolthoff JP, Goker M, Coates RC, Hadjithomas M, Pavlopoulos GA, Paez-Espino D, et al. 1,003 reference genomes of bacterial and archaeal isolates expand coverage of the tree of life. Nat Biotechnol 2017; 35:676-683.
  • 🧍 Members of the Subcommittee on the taxonomy of Campylobacter and related bacteria had noted that the specific epithet jejuni 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 jejuni. The correct etymology is: je.ju'ni. N.L. gen. neut. n. jejuni, of the jejunum.
