Phylogeny of Shiga toxin-encoding phage from SDi/SJo S. sonnei isolates. (A) progressiveMauve alignment of phage sequences. Sequences are centered by the stxA gene. str., strain. (B) A neighbor-joining tree based on an estimate of the shared gene content from the progressiveMauve alignment. The CA STX1 phage is indicated by yellow background color. The numbers over the branches designate branch length. The color of the node corresponds to the type of Shiga toxin.
