  • 🎓 Name mentioned 730 times in PubMed until 2025-06-04.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 According to Bartlett et al. (2022), this species is an established human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology (Reading) 2022; 168:0.
  • 🧍 This species encompasses two biovars (or biogroups), Sobria and Veronii. The proposal of the name Sobria is deprecated by the subcommittee on the taxonomy of Vibrionaceae, as this is the most common group in clinical material, yet it is indistinguishable phenotypically from the species Aeromonas sobria Popoff and Véron 1981. However, as a biovar designation, the name Sobria is not covered by the Bacteriological Code. Nevertheless, it is felt that the subcommittee should make a recommendation on this problem.
