Figure. . . Enterobacterial repetitive intergenic consensus sequence type 2 PCR patterns of pairs of Escherichia coli isolates from 6 patients examined during study of extended-spectrum β-lactamase–producing Enterobacteriaceae infection among liver transplant recipients, France, January 2001–April 2010. The pretransplant colonizing isolate (C) and the posttransplant infecting isolate (I) show identical patterns for patients 2, 3, and 6 and different patterns for patients 1, 4, and 5.
