Peptide nucleic acid of porcine reproductive and respiratory syndrome virus and uses thereof

摘要

The present invention discloses a peptide nucleic acid for porcine reproductive and respiratory syndrome virus (PRRSV) and use thereof. The peptide nucleic acid of the present invention is selected from any one or more from the peptide nucleic acids having a) a nucleic acid sequence of Sequence 1 as shown in the Sequencing List; b) a nucleic acid sequence of Sequence 2 as shown in the Sequencing List; c) a nucleic acid sequence of Sequence 3 as shown in the Sequencing List; and d) a nucleic acid sequence of Sequence 3 as shown in the Sequencing List. The peptide nucleic acid of the present invention has no toxic side effect and no resistance, is able to specifically directly inhibit the replication of PRRSV, has a good anti-viral effect, and suffers no food safety problems including drug residue and others.
