Genotype analysis of the O104 strains from bovine and clinical origins.

<p>(A) Hierarchical cluster dendrogram generated by array probeset differences for 241 strains including the diarrheagenic <i>Escherichia coli</i> collection representing the broad diversity across the <i>E</i>. <i>coli</i> species. Phylogroups are highlighted with color shading. The strains reported in this study from human clinical and bovine origin are highlighted in red and green boxes, respectively. Additionally, O104:H4 strains from the German and Georgian outbreaks [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196490#pone.0196490.ref015" target="_blank">15</a>] (indicated with asterisk) are used as reference. The scale bar represents the number of probeset differences. (B) Enlargement of the cluster region containing bovine and human <i>E</i>. <i>coli</i> O104:H7 strains from our study.
