Problems solved by technology

[0005] The purpose of the present invention is to provide a method for the preparation and use of a Mycoplasma pneumoniae rapid detection kit (LAMP), to improve the diagnostic efficiency of Mycoplasma pneumoniae, save time, and solve the problem that traditional detection methods cannot meet the development requirements of clinical diagnosis. After several experiments and tests, a method for clinical Mycoplasma pneumoniae detection using loop-mediated constant temperature amplification technology was finally explored. This method has the characteristics of rapid detection, convenience, and low cost.

Abstract

The invention relates to a mycoplasma pneumoniae rapid detection kit and a use method thereof, wherein the kit holds a loop-mediated isothermal amplification reaction tube and BstDNA polymerase; the reaction tube holds reaction buffer, dNTP, magnesium sulfate, a primer 1:5-ACCAATGCCATCAACCCG-3, a primer 2:5-TACCGGCGTAACGCAAAG-3, a primer 3:5-ATTTTCACCCGTGAGGGGGAGTTTTCGCTTAACCCCGTGAACG-3, a primer4:5-ACAGCGCTAAGGGCATCACTGTTTTTCAAAGCCGCTTCGGTTC-3, lycine, manganese chloride and calcein. The method for detecting mycoplasma pneumoniae comprises the following steps: extraction of a sample to be detected or bacterium DNA to be detected, loop-mediated isothermal amplification reaction of mycoplasma pneumoniae and colour development detection. The invention has the characteristics of accurate detection, high sensitivity, strong specificity, simpleness, convenience and rapidness.

Description

technical field [0001] The invention relates to a method for rapid detection of bacterial samples using a loop-mediated constant temperature amplification (LAMP) technology, in particular to a rapid detection kit (LAMP) for mycoplasma pneumoniae and a use method thereof. Background technique [0002] Mycoplasma pneumoniae (MP) is the pathogen of human mycoplasma pneumonia and one of the main pathogens causing respiratory tract infection and atypical pneumonia in children. More than 1 / 3 of non-bacterial pneumonia is caused by MP. MP is also an important pathogen of community-acquired pneumonia, and the infection rate in densely populated places is as high as 50%. Rapid and accurate detection of Mycoplasma pneumoniae is a prerequisite for effective prevention of Mycoplasma pneumoniae infection. At present, the clinical identification of Mycoplasma pneumoniae is usually carried out using traditional physiological and biochemical methods. However, due to the high requirements o...
