Figure 1. . EcoRI restriction patterns of transferred CMY-2–encoding plasmids of 18 Salmonella isolates. The result of the hybridization assay with the blaCMY-2 probe labeled with digoxigenin (Roche Molecular Biochemicals, Mannheim, Germany) is shown below the gel, and arrowheads indicate the locations of the restriction fragments that were hybridized. Lanes 2–21, plasmids from transconjugants of Salmonella isolates NB04.022, SB04.003, NL04.050, SA04.028, CG04.039, SG04.039, SG04.042, SE04.006, SG04.047, SE04.005, NG04.011, NG04.016, NG04.018, NC04.001, NC04.002, NC04.003, NC04.004, and CE04.015; lanes 1 and 22, molecular marker II (Roche Molecular Biochemicals); lanes 12 and 13, a 1-kb molecular marker (Promega Co., Madison, WI, USA).
