Abstract

The invention belongs to the field of molecular biology detection, relates to a mycobacterium tuberculosis rifampicin drug resistance detection method, and provides a method for detecting mycobacterium tuberculosis rpoB mutant genes. The method comprises the following steps of culture, extraction, amplification, purification, digestion, separation, gathering, image displaying and identification. Compared with the existing similar detection methods, the method of the invention adopts once culture, novel forward and backward primers are adopted, the purification step is adopted, the cracking digestion is adopted, the gathering step is adopted before the image displaying, a labeled digoxin antibody developing system is adopted, conventional equipment is adopted, and medicament can be easily obtained, so the method provided by the invention has the obvious advantages that the detection is fast, the detection rate is high, the map identification performance is good, the identification is accurate, the cost is low, and the like. The clinic diagnosis and treatment requirements can be more exactly and efficiently met.

Description

technical field

[0001] The invention belongs to the field of molecular biology detection, relates to a detection method for rifampicin drug resistance of mycobacterium tuberculosis, and provides a method for detecting rpoB mutation gene of mycobacterium tuberculosis. Background technique

[0002] In recent years, both developed and developing countries have seen a big rebound in the prevalence of tuberculosis worldwide. According to statistics, 1 / 3 (about 2 billion) people in the world have been infected with tuberculosis. There are about 20 million tuberculosis patients, about 9 million new patients occur every year, and the annual death toll is as high as 3 million. The emergence of multidrug-resistant tuberculosis (MDR-TB) / extensively drug-resistant tuberculosis (XDR-TB) poses a serious threat to global public health security and greatly increases the global tuberculosis control. burden. According to WHO data, the number of drug-resistant tuberculosis patients in China ...
