Phylogenetic analysis of Haemophilus influenzae (A), Klebsiella pneumoniae (B), Streptococcus pneumoniae (C) and Moraxella catarrhalis (D), based on the concatenated multigene data set. Within each phylogeny, the bacteria identified in this study are marked in red and highlighted with a red solid circle. All horizontal branch lengths are scaled to the number of nucleotide substitutions per site, and trees are mid-point rooted for clarity.
