  • Notes:
    • 🧬 The phylogenomic assignment score of this taxon is 0.01487 (N = 1).
    • 😷 The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 2, note = "PV?". — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 2, note = "ht". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
    • 🎓 Name mentioned 21 times in PubMed until 2026-06-11.
    • 🙆 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. 🇬🇧
    • 🧍 According to Rules 27(3) and 30 [1], this new species is not validly published because the effective publication only documents deposit of the type strain in a single recognized culture collection. However deposit in at least one other recognized culture collections in a different country is documented. Publication: De Vos P, Trüper HG. Judicial Commission of the International Committee on Systematic Bacteriology. IXth International (IUMS) Congress of Bacteriology and Applied Microbiology. Minutes of the meetings, 14, 15 and 18 August 1999, Sydney, Australia. Int. J. Syst. Evol. Microbiol. 2000; 50:2239-2244.
    • 🧍 In a Request for an Opinion, Euzéby and Tindall provide a solution whereby this name may be considered to be validly published [2]. Publication: Euzeby JP, Tindall BJ. Status of strains that contravene Rules 27(3) and 30 of the Bacteriological Code. Request for an opinion. Int J Syst Evol Microbiol 2004; 54:293-301. 🇫🇷
