Abstract

The invention discloses a mycoplasma nucleic acid isothermal amplification method. In particular, the mycoplasma nucleic acid isothermal amplification method includes the step that amplification is carried out in a reaction system, wherein the reaction system comprises specific primer pairs for amplifying mycoplasmas, and primers can be used for amplifying amplification products corresponding to mycoplasma feature sequences from a detection sample with an extra-low mycoplasma copy number. By means of the mycoplasma nucleic acid isothermal amplification method, the to-be-detected sample containing mycoplasma RNA can be rapidly amplified with high specificity, high flexibility and low pollution; and the mycoplasma nucleic acid isothermal amplification method is particularly suitable for amplification and detection of the to-be-detected sample containing mycoplasma genitalium MG and / or mycoplasma pneumoniae MP. The mycoplasma nucleic acid isothermal amplification method has the beneficial effects of being high in detection efficiency and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of biological detection of microorganisms, in particular to primers, probes and related kits used in the real-time fluorescent nucleic acid constant temperature amplification detection of mycoplasma by combining specific target capture technology and real-time fluorescent nucleic acid constant temperature amplification detection technology. Background technique [0002] Mycoplasma is a kind of prokaryotic microorganism between bacteria and virus, which lacks cell wall and can replicate independently. Parasites in the genitourinary tract of humans and other primates rely on highly specific parasitic mechanisms including unique apical organelle transplantation and invasion into human cells. [0003] In recent years, a large amount of epidemiological data suggest that Mycoplasma genitalium MG is a common pathogen of human genitourinary tract, is related to many non-gonococcal urethritis (NGU), prostatitis and p...
