Abstract

The invention belongs to the technical field of veterinary drug application, relates to a sulfated yeast beta glucan application in preparation of anti-animal-virus drugs and particularly relates to the application in preparation of anti-swine-flu viruses, porcine reproductive and respiratory syndrome viruses and porcine pseudorabies virus drugs. The sulfated yeast beta glucan application in preparation of the anti-animal-virus drugs has the advantages of being wide in antiviral spectrum, high in effective rate, safe and toxic-and-side-effect-free and residue-free, reducing or replacing utilization of antibiotics, belonging to a novel antiviral drug and having good application and development prospects.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine application, and relates to the application of sulfated yeast β-glucan in the preparation of anti-animal virus drugs, in particular to the application in the preparation of anti-swine influenza virus, porcine blue ear disease virus and porcine pseudorabies virus . Background technique [0002] With the rapid development of intensive and large-scale aquaculture, the incidence of animal diseases is getting higher and higher, especially the incidence of viral diseases is increasing, which has brought huge economic losses to the aquaculture industry. Although vaccine immunization can prevent the occurrence of such diseases to a certain extent, due to the increasingly accelerated mutation rate of pathogenic bacteria and the emergence of new super pathogenic microorganisms, the developed vaccines often have poor preventive effects or the developed vaccines Failure to keep up with the mutati...
