Unraveling the Armor of a Killer: Evasion of Host Defenses by African Swine Fever Virus

Ana Luisa Reis et al. J Virol. .

Abstract

African swine fever is an acute hemorrhagic disease of pigs. Extensive recent spread in the Russian Federation and Eastern Europe has increased the risk to global pig production. The virus is a large DNA virus and is the only member of the Asfarviridae family. In pigs, the virus replicates predominantly in macrophages. We review how the virus overcomes the barriers to replication in the macrophage and the virus mechanism to inhibit key host defense pathways.

Keywords: African swine fever; apoptosis; immune evasion; interferon; protein synthesis.

African swine fever virus in spleen samples from pigs infected with virulent virus. Pigs were infected with the virulent ASFV Benin 97/1 isolate, and after 3 days pigs were euthanized and tissue samples were collected. A section of infected spleen is shown with the myeloid-specific cell surface marker SWC3 (CD172a) labeled in green and the ASFV p54 protein in red. Bar, 30 μm.
