    • As of 2020-04-15 this emendation was not yet included in an IJSEM List of Changes in Taxonomic Opinion.
    • The genome of the type strain was sequenced as part of the GEBA (Genomic Encyclopedia of Bacteria and Archaea) project.

• Notes:
  • Nomenclatural type of the genus Pannonibacter Borsodi et al. 2003. Publication: Borsodi AK, Micsinai A, Kovacs G, Toth E, Schumann P, Kovacs AL, Boddi B, Marialigeti K. Pannonibacter phragmitetus gen. nov., sp. nov., a novel alkalitolerant bacterium isolated from decomposing reed rhizomes in a Hungarian soda lake. Int J Syst Evol Microbiol 2003; 53:555-561.
  • The 16S rRNA gene sequence data, DNA-DNA hybridization results, G+C content determinations, cellular fatty acid analysis and biochemical characterizations prove that strains of Achromobacter groups B and E belong to Pannonibacter phragmitetus (i.e. the three taxa represent a single species). Whilst Pannonibacter phragmitetus was described in 2003 from a Hungarian soda lake, it had been observed in human blood cultures in the UK since 1975. Publication: Holmes B, Segers P, Coenye T, Vancanneyt M, Vandamme P. Pannonibacter phragmitetus, described from a Hungarian soda lake in 2003, had been recognized several decades earlier from human blood cultures as Achromobacter groups B and E.
