Abstract

The invention relates to a feline coronavirus fluorescence EMA detection primer group, a kit and a detection method. The feline coronavirus fluorescence EMA detection primer group comprises an upstream primer, a downstream primer and a probe, the kit comprises a reconstitution fluid, a lyophilized enzyme tube containing primers, a positive quality control material and a negative quality control material. The detection method comprises the steps that the kit is used for performing a normal-temperature nucleic acid amplification technology, through the multiple enzymatic reactions of M-MLV reverse transcriptase, Rnase inhibitor, DNA helicase, single stranded DNA binding protein, DNA polymerase and the like, to-be-detected DNA is reversely transcribed to cDNA within 10-30 minutes under the constant temperature of 37-45 DEG C, the cDNA is amplified by millions of times, and rapid verification of the to-be-detected DNA can be achieved by cooperating with a fluorescence detection technology.The feline coronavirus fluorescence EMA detection primer group, the kit and the detection method have the advantages that the operation is simple, the time is short, the requirements for an instrument are low, and the feline coronavirus fluorescence EMA detection primer group, the kit and the detection method are suitable for the rapid diagnosis for pet infectious diseases.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a feline coronavirus fluorescent EMA detection primer set, a kit and a detection method. Background technique [0002] Feline Coronavirus (FCoV): According to statistics, 25% to 40% of domestic cats are positive for coronavirus, while in large cattery or breeding cattery, the positive rate reaches 80% to 100%. Although there may be no clinical symptoms at all after infection, feline infectious peritonitis may occur with a very high mortality rate. This disease often occurs in young adult cats under the age of four, especially in cats housed in groups. Currently, there is no effective vaccine for the prevention of feline infectious peritonitis, nor is there an effective drug treatment. Therefore, accurate diagnosis is crucial for the management and control of FCoV. [0003] At present, there are a few detection methods for feline coronavirus (FCoV) nucleic acid, mainly including PCR...
