Comparison of Escherichia coli O104:H4 isolates from Ontario. A) The XbaI pulsed-field gel electrophoresis profile of ON-2010 is distinct from those of ON-2011 and the outbreak strain from Germany. B) Optical mapping (NcoI) patterns reveal genomic similarities and differences between ON-2010, ON-2011, and the O104:H4 strain 55989. Blue, heterogeneity in siderophore biosynthesis region; red, strain-specific insertion of TetR-containing prophage.
