• Notes:
  • The e-mail address of the corresponding author given in the effective publication is not functional any more.
  • 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. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M.

  • According to Bartlett et al. (2022), this species is a putative human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology 2022; 168:0.
  • At the time of publication, the type strain was not deposited in two publicly accessible service collections in different countries, and Desulfomicrobium orale Langendijk et al. 2001 was not validly published [Rules 27(3) and 30]. However, according to the Judicial Opinion 81, Desulfomicrobium orale Langendijk et al. 2001 is now considered to be validly published, since deposit in a second culture collection in a different country has been documented.

  • The specific epithet orale is a Neo Latin adjective in the neuter gender, not a Latin noun in the genitive case as cited by Langendijk et al. 2001. Publication: Judicial Commission. Judicial Opinion No. 81. Int J Syst Evol Microbiol 2008; 58:1755-1763.
