POSSIBLE ANTICONTAGIOUS AGENTS IN FISH BREEDING
Nowadays there is a great attention to the agents based on ribonucleic acid for preventing infectious diseases of fish. The publication shows protective effect of Vestin based on double-helical ribonucleic acid made of yeast against Cyprinus carpio L. virus infections. The protective effect is shown after single preventive injection by means of intraperitoneal introduction or by means of hyperosmotic infiltration. Application of Vestin based on double-stranded RNA made of yeast against rhabdovirus infection Rhabdovirus carpio demonstrated high rate of protection from the virus of carp's spring viremia. The carp keeps high resistance to the virus more than 21 days after the single preventive injection of Vestin.
