• Notes:
  • Ochrobactrum pseudogrignonense is the correct name 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 Ochrobactrum.
  • The phylogenetic position of this species was determined in a genome-scale analysis by Hördt et al. (2020). Publication: Hordt A, Lopez MG, Meier-Kolthoff JP, Schleuning M, Weinhold LM, Tindall BJ, Gronow S, Kyrpides NC, Woyke T, Goker M. Analysis of 1,000+ Type-Strain Genomes Substantially Improves Taxonomic Classification of Alphaproteobacteria. Front Microbiol 2020; 11:468.
  • The full TRBA 466 classification is: risk group = 1, note = "+".
