• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Mycobacterium Lehmann and Neumann 1896 (Approved Lists 1980). Publication: Kusunoki S, Ezaki T. Proposal of Mycobacterium peregrinum sp. nov., nom. rev., and elevation of Mycobacterium chelonae subsp. abscessus (Kubica et al.) to species status: Mycobacterium abscessus comb. nov. Int J Syst Bacteriol 1992; 42:240-245. 🇯🇵
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Adekambi et al. (2006), Val-Calvo et al. (2025). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • ❗ Mycobacteroides is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 7; ATCC: 5; JCM: 3; CCUG: 3; NCTC: 2; CIP: 2; TMC: 1; KCTC: 1; BH: 1; LMG: 1.
  • 🧍 Medical researchers opposed the dissection of the genus Mycobacterium into several genera. Publication: Tortoli E, Brown-Elliott BA, Chalmers JD, Cirillo DM, Daley CL, Emler S, Floto RA, Garcia MJ, Hoefsloot W, Koh WJ, et al. Same meat, different gravy: ignore the new names of mycobacteria. Eur Respir J 2019; 54:1900795. 🇮🇹
