MIXED INACTIVATED VACCINE AGAINST IRIDOVIRUS INFECTION, STREPTOCOCCUS INFECTION, AND THEIR COMPLICATION IN FISHES

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a mixed inactivated vaccine, and to provide the vaccine capable of giving a countermeasure against infections in cultured fishes, because the cultured fishes frequently suffer from various infections and their complications caused by diversification of kinds of the cultured fishes and further suffer from drug resistant bacteria caused by frequently using chemotherapeutics, so that quality of the cultured fishes is deteriorated, production costs are increased due to disposal of died and diseased fishes, and therefore the countermeasure becomes one of the most important problems for the aquaculture industry. SOLUTION: This method for preparing the mixed inactivated vaccine comprises mixing at least two kinds of antigens the one of which comprises an inactivated antigen derived from a pathogen of the iridovirus infection in the fishes, and the other comprises an inactivated antigen derived from a pathogen of streptococcus infection. Thus, prevention of the above infection and complication is rapidly achieved in a labor-saving manner from geographical and temporal viewpoints, and further achieved at a low cost due to saved labors and expenses.
