Fig. 2From: Insights into the genome architecture and evolution of Shiga toxin encoding bacteriophages of Escherichia coliDiversity of STEC Stx phage genomes. The diversity of the 279 STEC stx phages was analyzed converting the shared proteins (phams) into a distance binary matrix using a python script and visualized in Splitstree (3D representation into 2D space). Clusters (a) and subclusters (b) are divided by colored circles (Green is Cluster A (subcluster A1 to A3), Purple is Cluster B, Orange is Cluster C, Blue is Cluster D, and Grey is Singleton). The scale bar indicates 0.01 substitutionBack to article page
