  • 🎓 Name mentioned 1222 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.
  • 🧍 There had been past discussion about the validity of the separation of the two closely related species, Aeromonas salmonicida and Aeromonas bestiarum [1]. However, Soler et al. [2] using MLST with the gyrB and rpoD genes among the genus Aeromonas, provided initial evidence for the clear phylogenetic divergence between these two species to warrant their remaining as separate species.
