• Notes:
  • De Vos et al. (2009) assigned this class to the phylum "Firmicutes" (Gibbons and Murray 1978) Garrity and Holt 2001. Publication: Ludwig W, Schleifer K-H, Whitman WB. Class III. Erysipelotrichia class nov. In: De Vos P, Garrity GM, Jones D, Krieg NR, Ludwig W, Rainey FA, K.-H. S, Whitman WB (eds), Bergey's Manual of Systematic Bacteriology, 2nd edn, vol. 3 (The Firmicutes), Springer, New York, 2009, p. 1298.
  • De Vos et al. (2009) assigned the genus Erysipelothrix Rosenbach 1909 (Approved Lists 1980) to this class. Publication: Ludwig W, Schleifer K-H, Whitman WB. Class III. Erysipelotrichia class nov. In: De Vos P, Garrity GM, Jones D, Krieg NR, Ludwig W, Rainey FA, K.-H. S, Whitman WB (eds), Bergey's Manual of Systematic Bacteriology, 2nd edn, vol. 3 (The Firmicutes), Springer, New York, 2009, p. 1298.
  • This taxon name is occasionally misprinted in some sources as: "Erysipelotri"; "Erysipelotrichi"; "Eysipelotrichia".
  • This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: May M, Brown DR. International Committee on Systematics of Prokaryotes Subcommittee on the taxonomy of Mollicutes: minutes of the meetings (closed and open), 1 and 5 June 2014, Blumenau SC, Brazil.

  • The BRCs most frequently used for deposits in this group are: DSM: 59; JCM: 33; ATCC: 26; CCUG: 19; CIP: 15; KCTC: 11; NCTC: 9; LMG: 4; VTT: 2; NBRC: 2.
  • Nomenclatural type changed from Erysipelotrichales Ludwig et al. 2010 based on new Rule 22. Publication: Oren A. Emendation of Rules 8, 15, 22, 25a, 30(3)(b), 30(4), 34a, and Appendix 7 of the International Code of Nomenclature of Prokaryotes. Int J Syst Evol Microbiol 2023; 73:6070.
  • This name was mentioned in a Request for an Opinion. Rule 8 of the 2022 revision of the ICNP does not require that the name of a class validly published before 1 January 2012 be formed from the stem of the name of the type genus of the type order of the class plus the ending ia. However, this name was already formed in that manner. Publication: Goker M. Solving the remaining problems with names of classes. Request for an Opinion. Int J Syst Evol Microbiol 2022; 72:5605.
