[Antigenic relationship between nucleocapsid proteins of phyto- and zoorhabdoviruses]

The methods of electrophoresis in PAAG and immunological method were used for comparative analysis of structural proteins of phytorhabdovirus of potato curly dwarf (PCDV) and zoorhabdoviruses-vesicular stomatitis virus (VSV) and fixed rabies Virus (RV). Molecular weight of viral proteins was determined by the method of polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The proteins with molecular weight 45-51 kD, are probably, the major component of the viral nucleocapsid. Nucleocapsid protein 45 kD RV virus was isolated by the method of preparative electrophoresis and then the monospecific serum was obtained. The Ouchterlony and immunoblotting method were used to show, that nucleocapsid proteins with molecular weights 51 and 45 kD both of phytorhabdovirus PCDV and zoorhabdoviruses VSV and RV are serologically related. The obtained data may be used in biotechnology as the basis for creation of a new class of diagnostic preparations with the purpose to detect RV virus using proteins of curly potato dwarf virus and may be also used in serological tests to reveal viruses of Rhabdoviridae family in various eukaryotic objects.
