Sequencing phylogeny of study NTHi isolates.

Abstract

<p>Radiation trees are presented for (A) 598 bases of the 16S rRNA gene, (B) 545 bases of the <i>recA</i> gene, and (C) the concatenation of these sequences (1143 bases). The trees are rooted by <i>H. parainfluenzae</i> T3T1 as indicated by yellow dots. Blue dots represent isolates that cluster with <i>H. influenzae</i> reference strains, orange dots represent closely related phylogenetic variants, red dots represent likely Hh isolates and green dots represent variants related to <i>H. parainfluenzae</i>. Colours were assigned based on the phylogenetic grouping of the concatenated sequences in radial tree C.</p
