title: [The electrophysiological properties of the structural polypeptides of the foot-and-mouth-disease virus].
abstract: The methodological approaches of isolation of preparations of FMDV structural polypeptides to analyse them by the electrophoresis and electro-focussing methods are presented. The value of isoelectric points of protein coat of FMDV structural polypeptides and corresponding them values of electric potential are determined. The similarity and differences of FMDV serotypes, characterized by the value of relative surface, falling on separate polypeptides, are determined for the virion structure on the basis of superposition principle. FMDV has been shown to possess the summarized negative charge of different values. The charge depends on the virus type and it is a determining condition for viruses resistance in environment. A graphical model of FMDV is suggested on the basis of systemic approach and it reflects the dipole character of electric charge distribution in virion structure and agrees with the virus model, built on the basis of icosahedron symmetry.
