  • 🎓 Name mentioned 6 times in PubMed until 2024-03-27.
  • 🧍 Consequently, the Subcommittee on the taxonomy of Vibrionaceae (1999) decided to clarify this problem [3]. Publication: Nair GB, Holmes B. International Committee on Systematic Bacteriology Subcommittee on the taxonomy of Vibrionaceae. Minutes of the meetings, 17 August 1999, Sydney, Australia. Int. J. Syst. Evol. Microbiol. 2002; 52:2331-2333.
  • 🧍 Later, another DNA relatedness data contradicted the previous results and according to Esteve et al. [4] the synonymy beetwen Aeromonas ichthiosmia and Aeromonas veronii should be reconsidered. Publication: Esteve C, Valera L, Gutierrez C, Ventosa A. Taxonomic study of sucrose-positive Aeromonas jandaei-like isolates from faeces, water and eels: emendation of A. jandaei Carnahan et al. 1992. Int J Syst Evol Microbiol 2003; 53:1411-1419.
  • 🧍 On the basis of 16S rRNA gene sequence analysis [1], DNA-DNA hybridization [2] and phenotypic data [2], Aeromonas ichthiosmia Schubert et al. 1991 seems a later heterotypic synonym of Aeromonas veronii Hickman-Brenner et al. 1988. Publication: Collins MD, Martinez-Murcia AJ, Cai J. Aeromonas enteropelogenes and Aeromonas ichthiosmia are identical to Aeromonas trota and Aeromonas veronii, respectively, as revealed by small-subunit rRNA sequence analysis. Int J Syst Bacteriol 1993; 43:855-856.
