Viruses as a biological weapon against farm animals.

Bioterrorist attacks could be catastrophic not only for the people (bioterrorism), but also for animals and plants (agroterrorism) and for economy of each country (national security). In this paper we have focused on two viruses extremely important from the veterinary point of view: (i) foot-and-mouth disease virus (FMDV; virus RNA) and (ii) African swine fever virus (ASFV; virus DNA), that are excellent examples of very dangerous infectious agents that can be used as a biological weapon for agroterrorist attacks.
