Pasteurellaceae is the single family of the order Pasteurellales 
– one of the 15 orders of the class Gammaproteobacteria 

Now 26 genera and 88 species with a valid name 

- and standing in nomenclature

Now with whole genome phylogeny based on 30 core proteins:

The figure shows a neighbour joining tree based 30 core proteins (concatenated) from the whole genomic sequences of type strains of species of
Species in red are type species of genera and you see that only 9 type species out of the 26 genera are yet known by whole genomic sequences.
Compared to the well-known 16S rRNA phylogeny, the avian genera Gallibacterium and Avibacterium are not monophyletic in the whole genomic tree. 
Note that many members of the original genera Actinobacillus, Haemophilus and Pasteurella still need reclassification to new genera if only the whole genome phylogeny is considered. The problem is most remarcable for Haemophilus with only 3 species included in the monophyletic group around the type species H. influenzae and 10 species scattered in the tree. Note the close relationship of H. felis with P. multocida.      

Members of the bacterial family Pasteurellaceae represent specialized commensals or parasites of vertebrates and they survive poorly outside their natural host

There are 88 species with a valid name in current use and they are included in 26 genera

Only 47 out of the 88 species are known by whole genomes of type strains
