Problems solved by technology

Among the existing pathogen detection methods for Mycoplasma hyopneumoniae, pathogen isolation is the most accurate method for the diagnosis of Mycoplasma hyopneumoniae pneumonia, but at present, the isolation, culture and identification of Mycoplasma hyopneumoniae in vitro is difficult, low-sensitivity, time-consuming, and requires complex equipment and culture conditions, so in developing countries and areas with limited clinical conditions in my country, it is particularly important to establish a simple and rapid diagnostic method
Although the polymerase chain reaction (PCR) method has high specificity and sensitivity, it requires expensive PCR machines, electrophoresis tanks and other precision instruments, and is not suitable for grassroots development.

Embodiment 1

[0080] The specificity result of embodiment 1LAMP detection method

[0081] LAMP amplification was performed on 1 strain of Mycoplasma hyopneumoniae, 3 strains of control Mycoplasma, 4 strains of control bacteria and water control, and the results were as follows figure 1 As shown, the Mycoplasma hyopneumoniae reaction tubes showed a rising curve of turbidity in about 13 minutes, which was a positive result. The curves of the 3 control Mycoplasma reaction tubes, the 4 strains of control bacteria reaction tubes and the water control reaction tubes showed no amplification, which was Negative result.

Embodiment 2

[0082] The sensitivity result of embodiment 2LAMP detection method

[0083] The initial concentration of the original DNA of Mycoplasma hyopneumoniae was 1.50×10ng / μL. After 10-fold serial dilution, LAMP and PCR amplification were performed, and the results were as follows: figure 2 and image 3 As shown, the results show that the detection limit of the LAMP method of the present invention is about 1.50×10-7 ng / μL, while the detection limit of the conventional PCR method is 1.50×10-5 ng / μL.

Embodiment 3

[0084] Fluorescence visualization detection result of embodiment 3 LAMP detection method

[0085] According to the optimized conditions monitored by the turbidimeter, fluorescent dyes were added to the reactor, and after 60 minutes of reaction at 63°C, observed under ultraviolet light, Figure 4 To observe the results, the left tube is the reaction of Mycoplasma hyopneumoniae genomic DNA as a template, which is a positive result, and the right tube is a negative control, which is a negative result. The test results show that the established LAMP method can be used conveniently at the grassroots level. You only need to use the kit with the LAMP primer designed by this method, add the sample, and use an inexpensive water bath to keep it at 63°C for 60 minutes to quickly observe the results without the need for Open the lid to avoid contamination.

Abstract

The invention discloses a mycoplasma hyopneumoniae loop-mediated isothermal amplification kit and the application thereof. The kit comprises LAMP primers, 2x reaction buffer, Bst DNA polymerase, a fluorescence visual detection reagent, ultrapure water and a mycoplasma hyopneumoniae DNA template, wherein the LAMP primers include outer primers F3 and B3, inner primers FIP and BIP, and loop primers LF and LB. The kit can be applied to detection of lesion tissue of suspected mycoplasma pneumoniae of swine and a mycoplasma hyopneumoniae culture. Specificity detection and sensitivity detection prove that by the adoption of the LAMP detection method, reaction can be monitored in real time, the mycoplasma hyopneumoniae copy number can be detected, a detection result can be obtained quickly and accurately, and convenience is brought to easy, quick and reliable detection of mycoplasma hyopneumoniae.

Description

technical field [0001] The invention relates to the technical field of microbial detection, in particular to a fast, visualized and real-time quantitative detection of Mycoplasma hyopneumoniae, a loop-mediated isothermal amplification kit and an application thereof. Background technique [0002] Mycoplasma hyopneumoniae (Mycoplasmahyopneumoniae, Mhp) is an important pathogen that causes mycoplasma pneumoniae (mycoplasmalpneumoniaofswine, MPS), also known as swine asthma. It was first isolated from a cell-free medium by Goodwin (1964), and then Shanghai Academy of Agricultural Sciences The Institute of Animal Husbandry and Veterinary Medicine isolated the pathogenic strain for the first time in 1973, which mainly causes chronic contact respiratory infectious diseases in pigs with cough and wheezing as the main symptoms. [0003] Mhp can be transmitted through the air, and it is difficult to isolate and block its transmission route, resulting in a high incidence of swine asthm...
