FIG 4 — Evolutionary model of E. coli O104:H4 emergence. Events in the emergence of E. coli O104:H4 are represented on the phylogeny of the isolates, including selected gain (green), loss (blue), recombination (orange), and SNP (red) events. Prophages are denoted in bold and plasmids in italic. See text for details and support for hypothetical gain, loss, recombination, and SNP events. Note that not all differences among genomes are represented here; most differences among isolates for which the ancestral state is not certain (for example, phage H on 55989) are not shown.
