Problems solved by technology

[0005] MDI analysis method: As a method of biopsy, the method of MDI analysis of mycoplasma has been controversial in the industry. This technology has the following shortcomings: there are as many as 7 kinds of mycoplasma that can be detected in genitourinary system diseases. There are difficulties in type identification; both L-form bacteria and mycoplasma lack cell walls, and the two are difficult to distinguish under a microscope; there is no standardized experimental plan in China, and the standardization of test results needs to be improved, but this technology is economical, intuitive and fast. typical characteristics of
However, the sensitivity of immunological binding detection is not high, and the mycoplasma fixed on the NC membrane sometimes reduces the specific staining and strengthens the cross-reaction between each mycoplasma

Abstract

The invention relates to the field of microorganism detection, in particular to an ureaplasma urealyticum PCR (Polymerase Chain Reaction) detection kit and a detection method thereof, aims to provide the ureaplasma urealyticum PCR detection kit and the detection method thereof for detecting a specific nucleic acid sequence of ureaplasma urealyticum in a clinical sample so as to fulfill the aim ofquickly judging the existence of the ureaplasma urealyticum. In order to fulfill the aim, the technical scheme is to provide the ureaplasma urealyticum PCR detection kit, which includes DNA (Deoxyribonucleic Acid) extract, PCR reaction solution, dNTPs, tap enzyme, UNG enzyme, positive control, negative control and a quantitative reference product, wherein the PCR reaction solution includes a primer A and a fluorescent probe A; and the primer is divided into an upstream primer A and a downstream primer A. The kit has the advantages of high flexibility and specificity, stability, timeliness, convenience in operation and the like.

Description

technical field [0001] The invention relates to the field of microorganism detection, in particular to a PCR detection kit for Ureaplasma urealyticum strains and a detection method thereof. Background technique [0002] Ureaplasma urealyticum (Ureaplasmaurealyticum for short UU) is one of the common parasites in the human genitourinary tract, which can cause disease under certain circumstances. The colonization in the human body may have a secondary upward trend, that is, the mother's birth canal infects the newborn during delivery, and then decreases rapidly; it gradually increases after sexual life. In recent years, urogenital tract infection caused by Ureaplasma urealyticum has been paid more and more attention, and it is one of the pathogens causing nongonococcal urethritis. Has now been listed as the pathogen of sexually transmitted diseases. [0003] Ureaplasma urealyticum is one of the common pathogens of genitourinary tract infection, usually superficial infection,...
