  1. 1 Final identification was assigned using 16S rRNA gene identification as the reference method and if required with supplemental conventional tests.
  2. 2 Assignment to taxonomic level: S = species, G = genus, N = not identified.
  3. 3 Correctness of assignment: SC = correct at species level, SI = incorrect at species level, GC = correct at genus level, GI = incorrect at genus level, N = not identified.
  4. 4 Taxon included in the VITEK 2 NH database; Capnocytophaga spp. is included as genus.
  5. 5 Accepted as correct genus as Haemophilus aphrophilus was renamed as Aggregatibacter aphrophilus[22].
  6. 6Pasteurella multocida is included in the database of the VITEK 2 ID GNB card (bioMĂ©rieux).
