Taxonomy/phylogeny:
 
About 15 species have been described within genus Pasteurella, but the relationship between members within the closely related genera Actinobacillus, Haemophilus, Mannheimia and Pasteurella is very uncertain since none of these genera forms monophyletic clusters.

New families introduced within the order Enterobacterales
Phylogenetic tree for the order <i>Enterobacteriales</i>.

The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.
