Purified Japanese flounder LCDV was used as a capture antigen of ELISA. Monitoring the immune response of Japanese flounder to LCDV was done using the sera obtained from apparently healthy, LCD-diseased and LCD-recovered fish. ELISA absorbances of these three groups were clearly different. Using the serum with high ELISA absorbance, the optimum ELISA condition was set up. Apparently healthy fish were injected with inactivated LCDV. One to three months after the injection, the antibody against LCDV was detected by ELISA established for LCDV and their ELISA antibody titer increased during that period.精製リンホシスチス病(LCD)ウイルスを ELISA 抗原として, ヒラメ健康魚, 発病魚および感染耐過魚の血中抗体検出を試みたところ, 群れごとに ELISA 吸光値に差が認められ, 値は上記の順に高かった。 感染耐過魚の血清を用い, 抗原および各抗血清の最適濃度ならびに ELISA のベースラインを決定した。 健康魚に不活化ウイルスを接種し, 最適 ELISA 条件下で血中抗体価を測定したところ, 接種1~3か月後に抗体価の上昇が観察され, 本 ELISA は免疫後の血中抗体価を測定するのに有効であると考えられた。日本魚病学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/53149https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/53149/1/article88.pdf0388-788X1881-7335AN00063165魚病研究3342072111998-10-20enginfo:doi/10.3147/jsfp.33.207publisher
