Description
(1)養殖場にクドア・セプテンプンクタータが寄生した種苗(稚魚)を導入しない。
(2)飼育環境を清浄化し、ヒラメへの寄生を仲介する環形動物を排除する。
(3)出荷前の成魚について、クドア・セプテンプンクタータが寄生していないことを確認する。
化学シフト(ppm)=((試料の共鳴周波数−基準物質の共鳴周波数)/基準物質の共鳴周波数)×106
・パーコール(登録商標)液を組織培養用培地(MEM)で希釈し、25%、36%、56%、60%の密度勾配液を調製する。
・重篤感染が確認されたヒラメの筋肉約10gを、リン酸緩衝液20ml中で約5mm角に切断する。
・100μmメッシュのフィルターで濾過し、濾過液を50ml遠心管に入れる。
・回転速度2500rpmで20分間遠心した後、上清を廃棄して沈殿したクドア・セプテンプンクタータの胞子を回収し、リン酸緩衝液2mlに懸濁させる。
・15ml遠心管に60%密度勾配液1mlを入れ、25%密度勾配液3ml及び胞子懸濁液を重層させる。
・回転速度2500rpmで30分間遠心した後、胞子の層を回収し、リン酸緩衝液2mlに懸濁させる。
・15ml遠心管に56%密度勾配液1mlを入れ、36%密度勾配液3ml及び胞子懸濁液を重層させる。
・回転速度2500rpmで20分間遠心した後、胞子の層を回収し、リン酸緩衝液2mlに懸濁させる。
・スイングロータを使用し、回転速度2500rpmで10分間遠心した後、上清を廃棄して沈殿した胞子を回収し、リン酸緩衝液100μlに懸濁させる。
