• Notes:
  • 🧒 Migula (1900) assigned the uncategorized "Thiobacteria" to this class. Publication: Migula W. System der Bakterien, Vol. 2. Gustav Fischer, Jena, 1900.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Bacteira"; "Bacteriaa"; "Bacterie"; "Bacterima"; "Bacteriota"; "Bacteriua"; "Bncteria".
  • 🖹 Minimal standards for the description of new taxa in this group were published in 2010. Publication: Tindall BJ, Rossello-Mora R, Busse HJ, Ludwig W, Kampfer P. Notes on the characterization of prokaryote strains for taxonomic purposes. Int J Syst Evol Microbiol 2010; 60:249-266.
  • 🖹 Minimal standards for the description of new taxa in this group were published in 2018. Publication: Chun J, Oren A, Ventosa A, Christensen H, Arahal DR, da Costa MS, Rooney AP, Yi H, Xu XW, De Meyer S, et al. Proposed minimal standards for the use of genome data for the taxonomy of prokaryotes. Int J Syst Evol Microbiol 2018; 68:461-466.
  • 🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: On SLW. Minutes of the inaugural 25 October 2022 meeting of International Committee on Systematics of Prokaryotes (ICSP) Subcommittees on Taxonomy representatives: challenges, trends, and perspectives for microbial taxonomists. Int J Syst Evol Microbiol 2023; 73:6075.
  • 🧍 No type order designated. Tindall (2014): "No identifiable type, not currently used as a class name; as applied by Haeckel (1894) the name encompasses all prokaryotes.". According to Rules 15, 22 and 27(3), the class Bacteria is illegitimate because it was proposed without the designation of a nomenclatural type. Publication: Tindall BJ. Names at the rank of class, subclass and order, their typification and current status: Supplementary information to Opinion 79. Judicial Commission of the International Committee on Systematics of Prokaryotes. Int J Syst Evol Microbiol 2014; 64:3599-3602.
  • 🧍 Rejected name (Opinion 128). No type order designated. Name also used at other ranks. Nomen dubium et ambiguum (Rule 56a). Publication: Goker M. Solving the remaining problems with names of classes. Request for an Opinion. Int J Syst Evol Microbiol 2022; 72:5605.
