Rapid detection of rifampicin-resistant Mycobacterium tuberculosis, based on isothermal DNA amplification and DNA chromatography

摘要

Rapid and easy detection of nucleotide point mutations in bacterial pathogens associated with drug resistance is essential for the proper use of antimicrobials. Here, we developed a rapid and simple method for the detection of mutations using Loop-mediated isothermal amplification (LAMP) combined with the single-tag hybridization (STH) chromatographic printed array strips (PAS) method. This procedure is able to detect four mutations (C1349 T, A1295C, G1303 T, A1304 T) in Rifampicin Resistance Determining Region (RRDR) of rifampicin-resistant Mycobacterium tuberculosis (RR-TB), simultaneously.
