Phylogenetic tree based on 16S rRNA of H. parasuis 29755 and type strains of some closely related species and other genera within the Pasteurellaceae. Also included is the only additional H. parasuis strain for which a genome sequence has been reported, SH0165. The tree was generated with the tree-builder available from the Ribosomal Database Project[27] using the Weighbor (weighted neighbor-joining) algorithm [28] with Jukes-Cantor distance correction [29]. Numbers to the left of branches indicate the percentage of trees in which each branch was represented in 100 replicates. An E. coli type strain was used as an outgroup.
