Application of carotene in preparation of medicine for resisting porcine hemagglutination encephalomyelitis virus infection

The invention relates to application of carotene in preparation of a medicine for resisting porcine hemagglutination encephalomyelitis virus infection, and belongs to the technical field of veterinary medicines. The technical problem that in the prior art, no special-effect treatment medicine for the porcine hemagglutination encephalomyelitis virus exists is solved. According to the invention, it is found for the first time that poison carotene can significantly inhibit the proliferation of porcine hemagglutination encephalomyelitis virus. A cell model verifies that on the basis of not damaging the cell activity, the toxic carotene can reduce the titer of the virus at an extremely low concentration (0.05 mu M), can significantly inhibit the proliferation of the virus at gene, protein and cell levels, is relatively high in safety, can be used as a potential drug for resisting porcine hemagglutination encephalomyelitis virus infection, and can be used for preparing a drug for treating porcine hemagglutination e
