  • 🧍 In the paper by Moore and Moore 1994, the genus Dialister is erroneously cited as Dialister (Olitsky and Gates). The genus Dialister was first proposed by Bergey 1923 not by Olitsky and Gates 1921. In 1921, Olitsky and Gates proposed the name "Bacterium pneumosintes". See also, The Index Bergeyana.

  • 🧍 Pittman et al. (1991) suggested the abbreviation "DILS" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM.

  • 🧍 Nom. rev. / Dialister (Olitsky; Gates 1921) as proposed by Moore; Moore 1994 seems incorrect; it should be: (ex Bergey et al. 1923).
