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 Flavobacterium Bergey et al. 1923 (Approved Lists 1980).Publication:

🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Obesumbncterium"; "Obesumbocterium"; "Obesunzbacterium"; "Obesurnbacterium"; "Obseumbacterium"; "Obsumbacterium"; "Ohesumbacterium".
🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP.Publication:

😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1".
🧍 Pittman et al. (1991) suggested the abbreviation "OBBT" for this genus name but this does not appear to be of practical relevance any longer.Publication:

🧍 There are two DNA-DNA hybridisation groups (HG) within Obesumbacterium proteus; these are separable by biochemical characters and DNA-DNA hybridisation. The type strain (ATCC 12841) falls in Group 1. Similarly, there are two groups within Hafnia. The type strain (ATCC 13337 = NCTC 8105) falls in Group 1, leaving Group 2 unnamed. However, despite having distinct phenotypic differences, Obesumbacterium proteus group 1 (type strain ATCC 12841) is 75% related to DNA group 1 of Hafnia alvei (though only 52% related to DNA group 2 of Hafnia alvei); these two organisms are thus a single species, Hafnia alvei. This leaves two separate unnamed groups (Obesumbacterium proteus HG2 and Hafnia alvei HG2) that are not closely related.Publication:

In July 2010, Huys et al. validly publish the name Hafnia paralvei for Hafnia alvei HG2 strains.Publication:
