The sequence of the Stx2a-encoding phage from the July 2014 Dorset County, England, outbreak strain of Shiga toxin–producing Escherichia coli O55:H7, designated 122262, showed >98% nt identity with an outlier Stx2a-encoding phage designated 155, found in a subset of isolates off Shiga toxin–producing Escherichia coli O157 geographically associated with the island of Ireland. The main difference between the 2 prophages was an insertion sequence element.
