Abstract

The invention relates to a primer group, a kit and a method for simultaneously detecting mycobacterium tuberculosis composite flora and rpoB gene mutation by LAMP. The primer group comprises a mycobacterium tuberculosis composite flora IS6110 gene amplification primer and an rpoB gene amplification primer group; the sequences of F3, B3, LF, LB, FIP and BIP of the mycobacterium tuberculosis composite flora IS6110 gene amplification primers are sequentially shown as SEQ ID NO: 4 to SEQ ID NO: 9; the rpoB gene amplification primer group comprises one or more of gene rpoB codon 516 wild type amplification primers, gene rpoB codon 526 wild type amplification primers and gene rpoB codon 531 wild type amplification primers; the F3, B3, FIP and BIP sequences of the gene rpoB codon 516 wild type amplification primers are sequentially shown as SEQ ID NO: 10 to SEQ ID NO: 13, the F3, B3, FIP and BIP sequences of the gene rpoB codon 526 wild type amplification primers are sequentially shown as SEQID NO: 14 to SEQ ID NO: 17, and the F3, B3, FIP and BIP sequences of gene rpoB codon 531 wild type amplification primers are sequentially shown as SEQ ID NO: 18 to SEQ ID NO: 21.

Description

technical field [0001] The invention belongs to the technical field of tuberculosis and drug-resistant gene mutation detection, and in particular relates to a primer set, a kit and a method for simultaneously detecting Mycobacterium tuberculosis complex flora and rpoB gene mutation by LAMP. Background technique [0002] Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, Mycobacterium bovis and Mycobacterium africanum, etc. It can affect various organs of the body, and tuberculosis is the most common. Mycobacterium tuberculosis is mainly transmitted through the air, and most people are asymptomatic after being infected with Mycobacterium tuberculosis, which is called latent infection. Latent infection can last for decades, and only 5%-10% of latent infection develop into active tuberculosis. Since the advent of therapeutic drugs one after another, tuberculosis has been basically cured. In recent years, the incidence of tuberculosis has been on...
