Method of extracting mycobacterium tuberculosis DNA and kit for detecting multiple drug resistance of mycobacterium tuberculosis

The invention discloses a method of extracting mycobacterium tuberculosis DNA and a kit for rapidly and accurately detecting multiple drug resistance (MDR) of mycobacterium tuberculosis. The method includes: extracting DNA to be detected from a clinical sample, determining mycobacterium tuberculosis infection by utilization of fluorescence real-time quantification PCR, indentifying whether the mycobacterium tuberculosis is drug-resistant or not and identifying the drug-resistant bacterial strain causing infection, and finally determining the pathogen infection quantity. The method can be used for detecting the whole drug-resistant genes with 29 sites that are determined to cause tubercle bacillus resistance to drugs (comprising rifampicin, isoniazide and ethambutol), and is the most comprehensive rapid molecular diagnosis system comprising tubercle bacillus drug-resistant genes so far. Through unique primers, probes and selection of fluorochrome marking designs, all the drug-resistant gene sites are detected by application of multiple qPCR. The application is simple, convenient and rapid. The results are accurate and reliable. The method and the kit have great practical value and wide application prospects for rapidly diagnosing tubercle bacillus infection and determining drug resistance, thus performing targeted treatment.
