  • ❗ Chryseomonas luteola is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Chryseomonas.

  • 🎓 Name mentioned 41 times in PubMed until 2024-03-28.
  • 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 Re-evaluation of the original taxonomy as Pseudomonas luteola IJSB 47:251. Publication: Anzai Y, Kudo Y, Oyaizu H. The phylogeny of the genera Chryseomonas, Flavimonas, and Pseudomonas supports synonymy of these three genera. Int J Syst Bacteriol 1997; 47:249-251.
  • 🧍 The level of similarity between the 16S rRNA sequence of the strain KS0921 G.L. Gilardi 4239 IAM 13000 JCM 3352 [the type strain of the species Chryseomonas luteola (Kodama et al. 1985) Holmes et al. 1987] and the 16S rRNA of the strain DSM 50071 ATCC 10145 [the type strain of the species Pseudomonas aeruginosa (Schroeter 1872) Migula 1900 (Approved Lists 1980)] is 94.0%. This result suggests that Chryseomonas Holmes et al. 1986 emend. Holmes et al. 1987 is a later synonym of Pseudomonas Migula 1894 (Approved Lists 1980), and that the name Pseudomonas luteola should be used for this species. Publication: Anzai Y, Kudo Y, Oyaizu H. The phylogeny of the genera Chryseomonas, Flavimonas, and Pseudomonas supports synonymy of these three genera. Int J Syst Bacteriol 1997; 47:249-251.
