Phylogenetic relationships based on the 5S (<i>rrf</i>) –23S (<i>rrl</i>) rRNA gene sequences between <i>Borrelia</i> spirochete isolated from <i>I. ovatus</i> tick (strain IO-TP-TW) in Taiwan and 14 other strains belonging to six genospecies of <i>Borrelia</i> spirochetes.

<p>The trees were constructed and analyzed by (<b>A</b>) neighbour-joining and (<b>B</b>) maximum parsimony methods using 1000 bootstraps replicates. Numbers at the nodes indicate the percentages of reliability of each branch of the tree. Branch lengths are drawn proportional to the estimated sequence divergence.
