• Notes:
  • ⏰ According to Collins et al. (1993), this species is an earlier heterotypic synonym of Aeromonas trota Carnahan et al. 1992. 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.

  • 🎓 Name mentioned 21 times in PubMed until 2024-03-27.
  • 🙆 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), no evidence of human infection was found for this species. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology 2022; 168:0.
  • 🧍 DNA-DNA hybridization studies are necessary in order to determine the genospecific relationship between these two species [2]. Publication: Nair GB, Holmes B. ICSB, SUBCOMMITTEE ON THE TAXONOMY OF VIBRIONACEAE: Minutes of the closed meeting, 19 May 1998, Atlanta, GA, USA. Int. J. Syst. Bacteriol. 1999; 49:1945-1947.
  • 🧍 Huys et al. 2002 wrote: "Although the species name A. enteropelogenes has nomenclatural priority, the authors would like to discourage the use of this name because the name A. trota has been cited much more frequently. The preferential use of A. trota in future publications may be the best option to avoid ambiguity in the description of ampicillin-susceptible aeromonads and to secure nomenclatural continuity in Aeromonas literature... To this end, it is anticipated that other workers may find additional arguments in order to formulate a Request for an Opinion from the Judicial Commission to overrule nomenclatural priority." The proposal by Huys et al. 2002 contravenes Rules 24(b) and 55. As long as a Request for an Opinion is not published and as long as the proposal by Huys et al. 2002 is not approved by the Judicial Commission, authors who consider Aeromonas enteropelogenes and Aeromonas trota to be synonyms must use the earlier synonym, Aeromonas enteropelogenes instead of Aeromonas trota. — 🧍 In the paper by Huys et al. 2002, Aeromonas enteropelogenes Schubert et al. 1991 is erroneously cited as Aeromonas enteropelogenes Schubert et al. 1990, and Aeromonas trota Carnahan et al. 1992 is erroneously cited as Aeromonas trota Carnahan et al. 1991. Publication: Huys G, Denys R, Swings J. DNA-DNA reassociation and phenotypic data indicate synonymy between Aeromonas enteropelogenes Schubert et al. 1990 and Aeromonas trota Carnahan et al. 1991. Int J Syst Evol Microbiol 2002; 52:1969-1972.
