Abstract

The invention discloses an RT-PCR (Reverse Transcription-Polymerase Chain Reaction) primer for detecting European and American porcine reproductive and respiratory syndrome viruses and a kit. The nucleotide sequence of an upstream primer of the primer is 5'-ATGTGGGATAGGGTGGACA-3', and the nucleotide sequence of a downstream primer is 5'-AAGAACCAGAAAAGACACCCAA-3'; the kit comprises the primer. The European and American RT-PCR primer and the kit are adopted for detecting whether the European and American porcine reproductive and respiratory syndrome viruses are positive, and have the advantages of high sensitivity, strong specificity, fastness, convenience and low detection cost and the like.

Description

technical field [0001] The invention belongs to the technical field of animal virus molecular biological detection, in particular to a pair of RT-PCR primers and a kit for detecting the European type and the American type of porcine blue ear disease virus. Background technique [0002] Porcine reproductive and respiratory syndrome (PRRS) is an acute infectious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV). The main clinical features are abortion, stillbirth, mummified fetus, and weak fetus. Difficulty breathing, etc. During the course of the disease, the skin of both ears will appear cyanotic and purple, so it is also called "blue ear disease". The disease was first reported in my country in 1996. [0003] According to the difference of PRRSV structural gene sequence, it can be divided into two genotypes of European type (represented by Lelystad Virus strain) and American type (represented by ATCC VR-232 strain). Among them, the American PRR...
