ABSTRACT
An inhibitory analysis of the role of glycosylation and glycoproteins in the manifestations of the most important properties of African swine virus was carried out using a set of strains and variants with contrasting characteristics. Glycoproteins were shown to realize some virus functions such as virulence and its variability, intracellular transport and exocytosis of virions, hemadsorption, but not immunological recognition of the infected cells by cytotoxic T-lymphocytes.

African swine fever virus polypeptides p14 and p31 are synthesized in the presence of phosphonacetic acid which inhibits viral DNA replication, and therefore they are early viral proteins. These polypeptides were found to be localized on plasma membranes by immunofluorescence with monospecific antisera and monoclonal antibodies and by selective solubilization of infected cells. The p14-specific antibodies mediate complement-dependent cytolysis and antibody-dependent cytotoxicity of the cells infected with African swine fever virus.
