Minimal spanning tree of the strains as shown in <b>Figures 1</b> and <b>2</b> using the same color code.

<p>The figure is based on the same data set as <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030624#pone-0030624-g001" target="_blank">Fig. 1</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030624#pone-0030624-g002" target="_blank">2</a>. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030624#pone-0030624-t001" target="_blank">Table 1</a> gives further information about assignment of biovar, genotype, and origin. Basic correlation and grouping of genotypes is similar compared to previously published <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030624#pone-0030624-g002" target="_blank">Fig. 2</a> in Morelli et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030624#pone.0030624-Morelli1" target="_blank">[6]</a>.
