 A Multiplex-PCR for virulence genes. M: DNA ladder (100 bp); Lane 1: control negative: DNA/RNA free water; Lanes 2–7 and 10–12: isolates positive for phoP/Q gene (299 bp); Lane 8: isolate positive for phoP/Q (299 bp), stn (617 bp), and slyA (700 bp); Lane 9: isolate positive for phoP/Q (299 bp) and slyA (700 bp). B Simplex PCR for dfrA1 (367 bp) gene. M: DNA ladder (50 bp); Lane 1: control negative: DNA/RNA free water; Lanes 2: control positive; Lanes 2–4 and 6–9: isolates positive for dfrA1 (367 bp) gene; Lanes 5, 10, and 11: isolates negative for dfrA1 gene. C Simplex PCR for tetA (577 bp) gene. M: DNA ladder (100 bp); Lane 1: control negative: DNA/RNA free water; Lane 2: control positive; Lanes 3 and 5–8: isolate positive for tetA (577 bp) gene; Lines 4 and 9: isolates negative for tetA gene
