Phylogenomic and Molecular Demarcation of the Core Members of the Polyphyletic Pasteurellaceae Genera Actinobacillus, Haemophilus, and Pasteurella

Figure 1

(a) A maximum-likelihood core genome phylogenetic tree of sequenced members of the family Pasteurellaceae. (b) A maximum-likelihood phylogenetic tree based on concatenated nucleotide sequence alignments of the 16S rDNA, infB, recN, and rpoB genes. Both trees are rooted using members of the Vibrionaceae (not shown). Nodes with >80% bootstrap support are indicated by diamond shaped symbols at the node. Clusters of species representing Actinobacillus sensu stricto, Haemophilus sensu stricto, Pasteurella sensu stricto, Aggregatibacter, and Mannheimia are indicated by brackets. Members of the genera Actinobacillus, Haemophilus, and Pasteurella which do not fall into their respective ā€œsensu strictoā€ clades are indicated by the presence of square brackets around their generic name (ex. [Pasteurella] pneumotropica).
