Embodiment Construction

[0021] The present invention is explained in detail below in conjunction with embodiment.

[0022] 1. Preparation of Sequences

[0023] According to the GeXP primer design requirements and the FMDV-O genome published by NCBI, select the conserved region to design specific primers, and form specific chimeric primers by adding universal primers, while the universal primer sequences belong to non-biologically derived nucleotide sequences , in addition to synthesizing the universal primer sequence, and adding a Cy5 fluorescent label to the 5' end of the upstream universal primer. The primer sequences capable of specifically amplifying foot-and-mouth disease type O virus nucleic acid of the present invention are: AGGTGACACTATAGAATAGTGACTGAACTGAACTGAACTGCTTTACCGCAT, which is named FMDV-O-F in the present invention; GTACGACTCACTATAGGGAGACATGTCCTCCTGCATCTG, which is named FMDV-O-R in the present invention. Universal primers used in the present invention: Cy5 AGGTGACACTATAGAATA, named...

Abstract

The present invention discloses a primer that can be used to detect O-type virus of foot-and-mouth disease, as well as a detection kit and preparation method prepared by using the primers. The gene sequences of primers for detecting foot-and-mouth disease O-type virus of the present invention are SEQ ID No.1, SEQ ID No.2, SEQ ID No.3, and SEQ ID No.4. Relevant experiments show that the primer sequence of the present invention can specifically and rapidly amplify the nucleic acid of foot-and-mouth disease type O virus, and the specific band can be detected by nucleic acid electrophoresis and has specificity. The invention can carry out high-throughput qualitative, qualitative and quantitative detection of foot-and-mouth disease virus. Compared with other existing methods and kits, the present invention has great advantages in port quarantine, animal circulation quarantine and laboratory diagnosis.

Description

technical field [0001] The invention relates to a primer, a detection kit and a preparation method that can be used for detecting foot-and-mouth disease type O virus. Background technique [0002] Foot-and-mouth disease (FMD) is an acute and severe infectious disease of animals caused by foot-and-mouth disease virus (FMDV), which mainly harms pigs, cattle, and sheeppox cloven-hoofed animals, and the incidence is extremely high. It has caused huge political and economic losses, so it is listed as the first class A infectious disease by the World Health Organization (OIE). FMDV can be divided into 7 serotypes, namely A, O, C, Asia 1, SAT 1, SAT 2 and SAT 3, and each serotype has many different subtypes, and each serotype There is no cross-immunity between them, and there is only partial cross-immunity between subtypes of the same serotype. [0003] The typing and differential diagnosis of foot-and-mouth disease virus has always been a research hotspot. Because there is no c...
