Figure 1From: First report of molecular detection of fluoroquinolone resistance-associated gyrA mutations in multidrug-resistant clinical Mycobacterium tuberculosis isolates in KuwaitSpecies-specific identification of M. tuberculosis isolates by multiplex PCR. Representative agarose gel of amplicons of multiplex PCR from 7 selected multidrug-resistant M. tuberculosis isolates (lanes 1-7) showing M. tuberculosis-specific amplification of two fragments of 473 bp and 235 bp (marked by arrows) from oxyR and rpoB genes, respectively. Lane M is 100 bp DNA ladder and the position of migration of 100 and 600 bp fragments are marked.Back to article page
