(A) Lanes: 1, sul1; 2, tetA(B); 3 and 4, qacE; 5 and 6, aphA1-Iab; and 7, molecular size marker (0.019 to 1.11 kb). (B) Lanes: 1, tetA(G); 2 and 3, tetA(A) (strains NCPH3633 and NCPH110); 4, strA; 5, qacE; 6, sul1; 7,blaTEM; 8, aadA2; and 9, molecular size marker. (C) Lanes: 1, molecular size marker; 2, strain NCPH3633 (a human Salmonella serovar Muenchen isolate of R type ACSSuTAxKGCfCro), 3, isolate UCE1; 4, isolate UCE3; 5, isolate UCM6 (the isolates in lanes 3, 4, and 5 are swine Salmonella serovar Muenchen isolates of R type ACSSuTAxK); 6, isolate UT30 (Salmonella serovar Typhimurium phage type DT193, swine isolate of R type AKSSuTG); and 7, isolate UW05 (a Salmonella serovar Typhimurium phage type DT104 swine isolate of R type AxACSSuT).
