• Notes:
  • 🧕 Boone et al. (2001) assigned this genus to the family Enterobacteriaceae Rahn 1937 (Approved Lists 1980). Publication: Garrity GM, Holt JG. The Road Map to the Manual. In: Boone DR, Castenholz RW, Garrity GM (eds), Bergey's Manual of Systematic Bacteriology, second edition, vol. 1 (The Archaea and the deeply branching and phototrophic Bacteria), Springer-Verlag, New York, 2001, p. 119-166.
  • 🚋 The type species of this genus has alternatively been placed in the genus "Paracolobactrum" Borman et al. 1944. Publication: Hoshina T. On a new bacterium, Paracolobactrum anguillimortiferum n. sp. Bulletin of the Society of Scientific Fisheries (Japan) 1962; 28:162-164.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Edwardisella"; "Edwardseilla"; "Edwardsiclla"; "Edwardsiealla"; "Edwardsiela"; "Edwardsielta"; "Edwardsietla"; "Edwardsrella"; "Edwardviella"; "Edwarsiella"; "Edwordsiella"; "Fdwardsiella".
  • 🧬 The phylogenomic assignment score of this taxon is 0.03902 (N = 5).
  • ✏ The authority of the taxon name (Ewing and McWhorter) deliberately differs from the authors of the publication (Ewing et al.).
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 7; CCUG: 5; JCM: 4; CIP: 4; NCTC: 4; ATCC: 4; NCCB: 2; LMG: 2; MCCC: 1; NCIMB: 1.
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 2, note = "Animal classification RG: 2 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 2". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🧍 According to Shipunov (2011), this name is a hemihomonym. Publication: Shipunov A. The problem of hemihomonyms and the on-line hemihomonyms database (HHDB). Bionomina 2011; 4:65-72.
  • 🧍 Edwardsiella Ewing and McWhorter 1965 (Approved Lists 1980) is a later homonym of a genus name with standing in the zoological (animal) nomenclature: Edwardsiella Andres, 1883. Principle 2 of the 2008 Code is not retroactive, so the name does not contravene the Code because of this homonymy. — Crook M. Personal communication, 2021-08-19.
  • 🧍 Pittman et al. (1991) suggested the abbreviation "EDWL" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM.
