FIG. 3.
PCR amplification of antimicrobial resistance genes among four plasmids isolated from Salmonella serovar Typhimurium phage type DT193 isolates. The identification number and resistance phenotype of each plasmid are indicated under each panel. The amplified genes shown in the five panels (A to E) are as follows: β-lactamase TEM (blaTEM) (lanes 1), aminoglycoside phosphotransferase (aphA1-Iab) (lanes 2), streptomycin-6-phosphotransferase (strA) (lanes 3), dihydropteroate synthase (sul1) (lanes 4), class B tetracycline resistance (tetB) (lanes 5), class I integron (int1) (lanes 6), aminoglycoside adenylyltransferase (aadA) (lanes 7), and gentamicin resistance methylase (grm) (lanes 8). Lanes M, molecular size markers.
