• Notes:
  • 🚋 The type species of this genus has alternatively been placed in the genus Spirochaeta Ehrenberg 1835 (Approved Lists 1980). Publication: Pohlschroeder M, Leschine SB, Canale-Parola E. Spirochaeta caldaria sp. nov., a thermophilic bacterium that enhances cellulose degradation by Clostridium thermocellum. Arch. Microbiol. 1994; 161:17-24.
  • 🚋 The type species of this genus has alternatively been placed in the genus Treponema Schaudinn 1905 (Approved Lists 1980). Publication: Abt B, Goker M, Scheuner C, Han C, Lu M, Misra M, Lapidus A, Nolan M, Lucas S, Hammon N, et al. Genome sequence of the thermophilic fresh-water bacterium Spirochaeta caldaria type strain (H1^T), reclassification of Spirochaeta caldaria, Spirochaeta stenostrepta, and Spirochaeta zuelzerae in the genus Treponema as Treponema caldaria comb. nov., Treponema stenostrepta comb. nov., and Treponema zuelzerae comb. nov., and emendation of the genus Treponema. Stand Genomic Sci 2013; 8:88-105.
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. The phrase "validly described" is misleading. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281.
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 1; ATCC: 1.
  • 🧍 As of 2022-08-12 this emendation was not yet included in an IJSEM List of Changes in Taxonomic Opinion.
