Applied multiplex allele specific PCR to detect second-line drug resistance among multidrug-resistant tuberculosis in China

In this study, we applied a multiplex allele-specific PCR (MAS-PCR) to identify the mutations on codons 90 and 94 of gyrA and nucleotide 1401 of rrs for detecting ofloxacin (OFX) and kanamycin (KAN) resistance in 139 MDR-TB isolates from China. Using the traditional phenotypic method as the reference, MAS-PCR detected resistance to OFX and KAN with sensitivities of 67.3% and 76.5%, respectively, and specificities of 100.0%.
