Abstract

Foot-and-mouth disease (FMD) is a highly contagious disease that affects cloven-hoof Animals including cattle, swine, sheep, goats, and lots of wild species. Effectively control measures are urged needed. Here, we showed that homoharringtonine treatment exhibited a strong inhibitory effect against two different strains of FMDVs (O/MYA98/BY/2010 and A/GD/MM/2013) in swine kidney (IBRS-2) cells. Further experiments demonstrated that homoharringtonine did not affect virus attachment or entry. Using time-of-addition assays, we found that the Antiviral activity of homoharringtonine occurred primarily during the early stage of Infection. These results demonstrated that homoharringtonine might be an effective anti-FMDV drug. Further studies are required to explore the Antiviral activity of homoharringtonine against FMDV replication in vivo.
