PROBLEM TO BE SOLVED: To separate and identify the pathogen of newly generated disease in sea culture fish or the like, and to provide an effective preventing means against the disease.SOLUTION: In inactivated vaccine formulation, regarding a yellowtail in which symptoms such as the white turbidity of eye balls for unknown reasons are developed in the farm in the Kagoshima prefecture of Japan, the pathogen is separated, and the pathogen is identified as streptococcus agalactiae, and the inactivated vaccine formulation is used against the streptococcus agalactiae infectious disease of sea culture fish. Against the risk of widely propagating and spreading the infectious disease in the farm of Seriola fish or the like and the risk of widely propagating the infectious disease even to the sea culture fish other than Seriola fish, by administrating the inactivated vaccine formulation to the sea culture fish, the generation, propagation and spreading of the infectious disease in the sea culture fish can be effectively prevented.COPYRIGHT: (C)2012,JPO&INPIT【課題】海面養殖魚などに新規に発生した疾患の原因菌の分離・同定、その疾患に対する有効な予防手段の提供。【解決手段】日本国鹿児島県の養殖場において、原因不明の眼球の白濁などの症状を発症したブリについて、その原因菌を分離、その菌をストレプトコッカス・アガラクティエと同定するとともに、その不活化ワクチン製剤であり、海面養殖魚のストレプトコッカス・アガラクティエ感染症に対する不活化ワクチン製剤。ブリ属魚類の養殖場などで、この感染症が広く伝播・蔓延する可能性、また、この感染症がブリ属魚類以外の海面養殖魚にまで広く伝播する可能性に対し、この不活化ワクチン製剤を海面養殖魚に投与することにより、海面養殖魚におけるこの感染症の発生・伝播・蔓延を有効に予防できる。【選択図】なし
