Problems solved by technology

[0004] Traditional detection methods for canine distemper mainly include virus isolation and culture, ELISA detection, immune test strip detection and RT-PCR detection, etc. There are problems such as low sensitivity or low specificity. At present, many patents use RT-PCR or LAMP methods. These methods have high sensitivity and specificity, but require expensive instrument reagents and require high technical requirements for operators. At the same time, it takes a long time, so it cannot be used for grassroots and on-site inspections

Abstract

The invention relates to primer pairs for fluorescence EMA detection of canine distemper virus (CDV), a kit and a detection method. The primer pairs for fluorescence EMA detection of canine distempervirus (CDV) contain a forward primer, a reverse primer and a probe. The kit comprises the following contents: a redissolved solution, a lyophozyme tube containing primers, a positive quality control and a negative quality control. The detection includes the process of carrying out a normal-temperature nucleic acid amplification technology by using the kit. Through multiple enzymatic reactions of M-MLV reverse transcriptase, a Rnase inhibitor, DNA helicase, single-stranded DNA binding protein, DNA polymerase and the like, RNA to be tested can undergo reverse transcription into cDNA under the condition of constant temperature 37-45 DEG C within 10-30 min, and the cDNA is amplified by millions of times; and and with the cooperation of the fluorescence detection technique, rapid detection of RNA to be tested can be realized. The detection method of the invention has advantages of simple operation, short time and low requirement on equipment, and is suitable for rapid diagnosis of pet infectious diseases.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a fluorescent EMA detection primer set, a kit and a detection method for canine distemper virus. Background technique [0002] Canine distemper (Canine Distemper) is a highly contagious disease caused by canine distemper virus (Canine Distemper virus, CDV). According to the statistics of the list of animal diseases released on December 11, canine distemper belongs to the third category of animal diseases, mainly infecting dogs and cats. The transmission channel is mainly through direct contact with sick animals, and can also be transmitted through air or food. Belongs to zoonotic diseases. [0003] Under natural conditions, canine distemper can infect dogs of different ages, sexes and breeds, but it is the most susceptible to juvenile puppies. Other studies have shown that in addition to canids, many animals such as mustelidae, raccoons, and giant pandas can also be infected. It is...
