Figure 3. Minimum spanning tree (MST) of φPOC-J13 phage sequences.

Figure 3.

The MST was inferred from the alignment including 36 full genome φPOC-J13 sequences isolated from stx-encoding S. flexneri 2a strains (except for a few phages isolated from other Shigella spp., indicated by arrows), plus the φPOC-J13 reference sequence (GenBank accession no. KJ603229). Each circle represents a phage sequence colored by country of origin according to the legend in the figure. Unknown country of origin indicates that the infected patient did not have a known travel history available. The last two digits of each strain label indicate the time of sampling (2001–2014). The number along an edge is the number of SNPs separating two connected sequences. The clade including most of the Haitian strains is indicated with an ellipse.
