S1-PFGE pattern for strain CWH001 and southern blotting for the blaNDM-1, blaTEM-1 and blaVEB-3 genes. Lanes: Marker, Salmonella serotype Braenderup strain H9812 as a reference size standard; 1, PFGE result for S1-digested plasmid DNA of strain CWH001; 2–4, southern blot hybridization with the probes specific to blaNDM-1, blaTEM-1 and blaVEB-3, respectively. Full length S1-PFGE and southern blotting results are presented in Supplementary Fig. S1.
