• Notes:
  • Aeromonas bestiarum Ali et al. 1996 was previously known as Aeromonas hydrophila genomospecies 2. {2} There had been past discussion about the validity of the separation of the two closely related species, Aeromonas bestiarum and Aeromonas salmonicida [1].

Minutes of the Meetings, 25 July 2005, San Francisco, CA, USA. Int. J. Syst. Evol. Microbiol. 2009; 59:2633-2637.
  • There had been past discussion about the validity of the separation of the two closely related species, Aeromonas bestiarum and Aeromonas salmonicida [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.

  • The full TRBA 466 classification is: risk group = 1, note = "ht+".
