Figure 2. Plasmid profile (A) and hybridization with CTX-M-9 probe (B) and CMY-2 probe (C). The studied isolates, by lane, are: 1: P5, 2: P6, 3: P6T (transconjugant of P6), 4: P9, 5: P10-1, 6: P12-1, 7: P12-2, 8: P14, 9: P15, 10: P18-1, 11: P19, 12: F2, 15: P10-2, 16: P18-2, 17: P18-2T (transconjugant of P18-2), 18: F3-1, 13, and 14: plasmid control strains E. coli 678 CECT (= NCTC 50193 with the following plasmid sizes: 54.38, 7.30, 5.56, 5.14, 3.98, 3.08, 2.71, and 2.06 kb) and E. coli 679 CECT (= NCTC 50192 with the following plasmid sizes: 148.5, 63.8, 36.2 and 7 kb.). M is marker III (Roche Diagnostics GmbH, Mannheim, Germany). Below each lane in panel A is indicated the plasmid profile designation shown in the Table.
