| Taxonomy/phylogeny:
|
About 2 species have been described within genus Glaesserella, but the relationship between members within the closely related genera Actinobacillus, Glaesserella, Haemophilus, Mannheimia and Pasteurella is very uncertain since only few of these genera forms monophyletic clusters.
Note that the name of this bacterium is still Haemophilus parasuis in the phylogenetic tree. |
