AbstractIn 2019, diarrhea cases occurred on cattle farms in Qionglai and Guang'an, Sichuan Province. Two out of 20 (10%) serum and nasal swab samples were positive when tested using a bovine viral diarrhea virus (BVDV) antigen-capture ELISA kit. Two non-cytopathic strains of BVDV were isolated and named QL1903 and GA190608, respectively. The nucleotide sequences of the genomes of the two isolates were 89.52% identical. Phylogenetic analysis based on the 5'-UTR sequence revealed that the BVDV isolate QL1903 belonged to BVDV subtype 1b, whereas isolate GA190608 clustered with strains HN1814, EN-19, and BJ09_26 in a separate branch, which has tentatively been classified as a new genetic subtype, "1v".

Plant products provide an alternative and successful source of lead compounds for the pharmaceutical industry. The present study was aimed to evaluate, in cell-based assays, the antiviral properties of essential oils obtained from plants that commonly grow in Sardinia, Italy, against a broad spectrum of RNA/DNA viruses. The essential oils of Helichrisumitalicum (Roth) G. Don ssp. microphyllum (Willd.) Nyman, Laurus nobilis L., Mirtuscommunis L., Pistacia lentiscus L., Salvia officinalis L., Saturejathymbra L., Lavandula angustifolia Mill., Foeniculum vulgare Mill., and Eucalyptus globulus Labill. were extracted by hydrodistillation and analyzed by gas chromatography mass spectrometry (GC–MS). Interestingly, the essential oil of Salvia officinalis showed moderate activity against bovine viral diarrhea virus (BVDV), an enveloped RNA virus belonging to the Flaviviridae family. BVDV is responsible for several clinical manifestations in bovines, including respiratory, gastroenteric, and reproductive diseases, with a significant economic impact. With the aim to individuate the constituent of the Salvia officinalis responsible for the biological activity, we tested the major components of the oil: camphene, β-pinene, limonene, 1,8-cineole, cis-thujone, camphor, (E)-caryophyllene, and α-humulene. Here, we describe α-humulene as an active component that is non-cytotoxic and active against BVDV (EC50 = 36 µM). Its antiviral effects were evaluated using virucidal cytopathic effect inhibition and viral yield reduction assays. This is the first scientific report showing the anti BVDV effects of Salvia officinalis essential oil and α-humulene as the main active component.
