Bacteria in the family Pasteurellaceae have been classified into a number of genera based on metabolic properties, but these classifications are not generally accurate reflections of the evolutionary relationships between different species.
Molecular signatures in the form of CSIs have also been used to help resolve polyphyletic distribution of three main genera within the family Pasteurellaceae: Actinobacillus, Haemophilus, and Pasteurella.
[5][6][7] These genera demonstrate extensive polyphyly across the family, however, CSIs have been found to be consistently shared by certain species that form a monophyletic group within each respective genus.
The designation was conceived to accommodate a collection of gram-negative organisms currently representing 34 genera and 105 species, described as “specialized commensals, primarily and potential pathogens of vertebrates–mainly mammals and birds.” [9]
