abstract
The protein spectrums of blood serums and livers of sturgeons of the Caspian Sea and their parasites were obtained by the method of polyacrylamide gel disc electrophoresis. Each protein fraction is characterized by the relative electrophoretic mobility (REM). The similarities of protein fractions of parasites and fish tissues was revealed in REM. The greatest number is noted in the zone of the location of globulin proteins, which are responsible for the formation of antibodies. It has been established that parasites belonging to different classes, but parasitizing same family of fish, operate the same mechanism of adaptation to the hosts. The fractions with high REM, without the hosts was found in the electropherograms of the protein spectra of parasites.
