Experimental studies of the effect of Rhabdovirus infection on hematological, immunological and biochemical indicators in cold-blooded animals

Bactericidal activity of blood serum (BABC), content of lysozyme, protein in it were recorded as well as formula and form of erythrocytes, activity of digestive enzymes by results of free amino acid accumulation in the food substrate were determined ten days after rhabdovirus injection to one-year-old carp. It is shown that if there are no clinical symptoms of viremia in carps, BABC, relative number of stab neutrophils and the value of eccentricity index in erythrocytes increase. Simultaneously stimulation of the activity of digestive enzymes and formation of free amino acids in chyme whose content is higher than that in the intact fish are observed in such fish. Free amino acids are discussed for expediency to be used as an additive to the folder for increasing resistivity of fish to infections.
