Problems solved by technology

Due to the limitations of fluorescent reporter groups and instrument detection channels, the mutation types that can be detected by one PCR mix are limited, and multiple PCR mixes are required to meet the detection of so many mutation types, which is costly
Currently there is no product and method for comprehensive and rapid genotyping of Helicobacter pylori and detection of drug-resistant mutations

Embodiment 1

[0061] Embodiment 1 The implementation of the concrete technical scheme of the present invention

[0062] 1. Technical basis

[0063] 1.1 Design and implement primers and amplification reaction solution according to the known HP genome sequence.

[0064] The main research content is: according to the sequence characteristics of UreA, CagA, and VacA genes in the HP genome, design PCR primers to amplify the target fragments for typing detection; according to the 23S rRNA, 16S rRNA, rdxA genes, PBP1 Gene and gyrA gene sequence characteristics, design PCR primers to amplify the target fragments for drug resistance detection; in addition, IC internal control is also designed to monitor the entire experimental process.

[0065] The PCR reaction solution is divided into 4 tubes, two tubes of typing reaction solution (the first tube of VacA gene intermediate region primer and signal sequence primer, the second tube of UreA and CagA gene amplification primers), two tubes of drug resis...

Embodiment 2

[0113] Use of Helicobacter pylori typing and drug-resistant mutation gene detection kit of the present invention

[0114] 1. Uses: HP typing and drug-resistant mutation gene detection for patients with gastritis, gastric ulcer, and gastric erosion before initial treatment or retreatment can:

[0115] 1. Distinguish type I and type II, and determine the virulence of Helicobacter pylori;

[0116] 2. Detect 15 mutation types at 9 hotspot mutation sites of 5 HP therapeutic drugs;

[0117] 3. Assist in determining individualized clinical diagnosis and treatment plans, and conduct HP epidemiological research.

[0118] 2. Background of clinical indications:

[0119] Helicobacter Pylori (HP) was first isolated from the gastric mucosa of gastritis patients in 1983 by Barry J. Marshall and J. Robin Warren. Studies have shown that inflammation caused by HP can lead to atrophic gastritis, intestinal metaplasia, dysplasia, and eventually gastric adenocarcinoma.

[0120] HP contains two...

Abstract

The invention relates to a gene detection kit, in particular to a helicobacter pylori (HP) type and drug-resistant mutation gene detection kit. The kit comprises PCR (polymerase chain reaction) solutions and nucleic acid membrane strips for HP type and drug-resistant mutation gene detection; the PCR solutions comprise a PCR solution I, a PCR solution II, a PCR solution III and a PCR solution IV; the PCR solutions also contain a pair of internal control primers respectively. The HP type and drug-resistant mutation gene detection kit can be used for distinguishing two types of HP in one test, and can be used for detecting 15 mutation types of 9 hot spot mutational loci related with drug fastness of 5 therapeutics, a VacA gene and a CagA gene are used for typing, and a reference basis is provided for judgment of illnesses. Mutation types of drug-resistant mutation detection are more and more comprehensive, and the condition of genotypic resistance of HP from which a patient suffers is quickly and comprehensively evaluated.

Description

technical field [0001] The invention relates to a gene detection kit, in particular to a Helicobacter pylori typing and drug resistance mutation gene detection kit. Background technique [0002] Helicobacter Pylori (HP) was first isolated from the gastric mucosa of gastritis patients in 1983 by Barry J. Marshall and J. Robin Warren. Studies have shown that inflammation caused by HP can lead to atrophic gastritis, intestinal metaplasia, dysplasia, and eventually gastric adenocarcinoma. [0003] The whole gene sequence of HP has been determined, and the urease gene has four open reading frames, which are UreA, UreB, UreC and UreD. The polypeptides encoded by UreA and UreB are structurally equivalent to the two subunits of the urease structure. The urease of Helicobacter pylori is extremely rich, containing about 15% of bacterial protein, and its activity is 400 times that of Proteus. Urease catalyzes the hydrolysis of urea to form an "ammonia cloud" to protect bacteria from...
