Abstract

The generation of antiviral drugs from herbs and other natural resources with traditionally long-confirmed effects is an efficient approach. So far, no herb or components from herbs that could inhibit bovine herpesvirus type 1 (BoHV-1) replication have been described. In this study, the antiviral effect of curcumin, anatural phenolic constituent of the spice turmeric, on BoHV-1 replication was evaluated in cell culture. We demonstrated that curcumin impairs BoHV-1 viral particles and affects the virus post-binding entry process. Furthermore, curcumin upregulated the proportion of the plasma membrane adopting alipid raft conformation in MDBK cells, which supported the previous reports that curcumin can modulate the lipid bilayer. Though the antiviral mechanism of curcumin on BoHV-1 needs further study, we identified for the first time acomponent from herb that could inhibit BoHV-1 replication, in vitro.
