Abstract

The present invention provides a kit for the constant temperature detection of bacterial pathogens of respiratory tract infection with enzyme-cleavage probes. The primers and probes of 12 pathogen targets are combined into four triple nucleic acid reaction solutions, and the probes for detecting each bacterial pathogen contain one RNA. Base probes and include 6 isothermal amplification primers. Using the nucleic acid detection kit provided in the present invention, four single-tube multiple constant temperature amplification can be used to detect 12 kinds of bacterial pathogens with high frequency in respiratory tract infections, and the kit is easy to operate, and bedside detection can be realized, and the entire detection time Within 30 minutes, it can quickly and accurately screen a variety of bacterial pathogens in the sample to be tested.

Description

Technical field [0001] The invention involves the field of nucleic acid constant temperature detection technology, and specially involves a kit that specializes in the aquacilids infection of bacterial disease infection with enzyme cutting probe. Background technique [0002] Highness of respiratory infection is common in clinical clinical. Bacterial infections are common causes of respiratory diseases. There are many pathogenic bacteria that cause respiratory bacterial infections. In adult respiratory bacterial infections, golden pylori, copper green single bacteria, and Bowman Berobacteria, pneumonia, albumin, Bacteria, Bacteria, Puomy Legion, Enterprise, Pneumococcus, Pseudomonal Malcaria, Pseudoma, Onion Berk Holde The 12 are the most common. Therefore, it can achieve specific and rapid screening tests for the common bacterial diseases of these 12 respiratory tracts, which facilitates clinicians to diagnose patients in a timely manner and provide appropriate medication treatm...
