| Research Abstract |
In this study, we developed a novel fish-immunization with a synthetic double-stranded RNA [Poly(I:C)] and live pathogenic viruses. The fishes immunized with live pathogenic virus, followed by administration of Poly(I:C), became a transient, non-specific antiviral state, and those fish survive the initial immunization with live virus, thereby mounting a specific protective immune response against the injected pathogenic virus. Strong protective immune response was observed in rainbow trout, Japanese flounder and sevenband grouper by Poly(I:C)-immunization with IHNV, VHSV and NNV, respectively. It is conceivable that Poly(I:C)-immunization will eventually be applicable to a wide range of fish species as well as other viruses.
