Multiplex PCR for M. tuberculosis, M. bovis and M. bovis bacillus Calmette-Guérin (BCG) strains. PCR products were separated by electrophoresis and visualized. Lanes M: molecular size marker (100-bp ladder); 1: M. bovis BCG Pasteur; 2: M. bovis BCG Tice; 3: M. bovis BCG Tokyo; 4: M. bovis AN5; 5: M. tuberculosis H37Rv; 6: negative control. Expected sizes of PCR products are shown. RD, regions of difference; PCR, polymerase chain reaction; ESAT-6, early secreted antigenic target 6 kDa protein.
