Problems solved by technology

At present, there are few kits for detecting MG based on PCR technology in China, and the degree of automation is not high, the detection time is long, and the false negative is high. Therefore, it is necessary to develop a simple and fast reagent with high sensitivity, short detection time, low false positive The box is the problem that needs to be solved

Abstract

The invention relates to the technical field of medical detection, in particular to primers for detecting mycoplasma genitalium, a probe for detecting mycoplasma genitalium, a kit for detecting mycoplasma genitalium and a detection method. The primers and the probe comprise a primer pair of nucleotide sequences shown in SEQ ID NO:1-2 as shown in the description and a probe of a nucleotide sequenceshown in SEQ ID NO:3 as shown in the description. The provided primers and probe can specifically bound to a mycoplasma genitalium outer membrane protein B gene and a human beta-globin gene, the detection sensitivity and specificity are significantly improved, the positive rate of low-value samples reaches 100%, and detection results are accurate and reliable so that the primers, probe and kit for detecting mycoplasma genitalium and the detection method can be applied to clinical detection of mycoplasma genitalium.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a primer, a probe, a kit and a detection method for detecting mycoplasma genitalium. Background technique [0002] Mycoplasma genitalium (Mycoplasma genitalium, MG) belongs to Mycoplasma family Mollicola, is one of the pathogens that cause non-gonococcal urethritis (NGU). In addition, MG is closely related to sexually transmitted diseases such as pelvic inflammatory disease (PID), obstetric complications, prostatitis, epididymitis, and balanitis. In recent years, studies have found that MG infection may also be related to the occurrence and development of tumors and human immunodeficiency virus (HIV). [0003] The 2016 European guidelines for Mycoplasma genitalium infection state that the prevalence of Mycoplasma genitalium in men with non-Chlamydial nongonococcal urethritis (NCNGU) ranges from 10% to 35%. In China, the infection rate of Mycoplasma genitalium in STD c...
