Description
P.salmonis抗原と抗−アースロバクターポリクローナル抗体の交差反応性
CHSE−214細胞培養物から収集した3回洗浄済みP.salmonis細菌細胞(約25μg)をLaemmli緩衝液(100μl)と混合し、95℃で3分間加熱した。サンプル(10μl)を9%アクリルアミドゲルに充填し、150ボルトで1時間電気泳動にかけて、タンパク質を分離した。このタンパク質を半乾燥トランスブロッター(BIORAD)を用いて100% ニトロセルロース膜に移した。タンパク質の移動は20ボルトで50分間実施した。
アースロバクターワクチンのSRSに対する防御
ギンザケ(治療群あたり110匹、平均体重10g)を12℃で一般的な操作手順に従って水槽水中に正常な養殖条件下で維持した。1週間の順化後、第1群、第2群及び第3群のそれぞれに対して食塩液希釈剤中で再構成した105、106及び107cfu/用量の凍結乾燥アースロバクターsp.nov細胞(Renogen(商品名))0.1mlを腹腔内にワクチン接種した。第4群及び第5群は、食塩液希釈剤中に12.2μg及び50μg/用量の“Peptimune”を添加する以外は第1群と同様に処置した。Peptimuneは、液体培養物(MTSBブロス)中で>1×E9の細胞密度まで増殖させた熱死滅アースロバクターの調製物であり、12及び50μg/投与を投与するようにタンパク質アッセイにより標準化されている。第6群及び第7群は、P.salmonisバクテリンをワクチン接種したポジティブコントロールであった。前記バクテリンはP.salmonis型菌株LF−89を感染させたCHSE−14細胞培養物の上清から4℃において0.125%ホルマリンを用いて少なくとも72時間かけて作製した。U/F濃縮を用い、濃縮上清を8μg(タンパク質)/0.1ml用量を取り込むように使用した。バクテリンワクチンは1匹の魚あたり20μg(第6群)及び100μg(第7群)のUltracorn(フランス国のVirbac)を用いてデリバリーした。Ultracornは、超音波処理したコリネバクテリウム・クティス(Corynebacterium cutis)溶解物に基づく免疫賦活剤である。注射前に抗原を等容量の鉱油アジュバントで乳化した。ネガティブコントロール群(第8群)には食塩液を注射した。
ワクチン接種から471dd及び1441ddに、2重化群の魚類(25匹/処置)にビルレントP.salmonisを腹腔内注射して攻撃誘発した。ビルレントP.salmonisはCHSE−14細胞上で最低2〜3週間培養した。少なくとも50% CPEに達する培養物の上清を腹腔内注射のために用いた。ビルレントP.salmonisは10−2以上の希釈度で0.1ml/魚(n=25)の量を注射した。攻撃誘発した魚は12℃で維持した。
感染から32日後471ddの攻撃誘発から生残した魚(n=7〜10)の組織サンプルにおけるSRS感染レベル
Renogenは、ワクチン摂取後471dd及び1441ddにP.salmonisの直接攻撃誘発に対して十分な防御を与えた。このワクチンは一般的な油ワクチンによる防御よりも優れていた。本発明者らは、Renogen(商品名)群では、より少ない数の生残魚が臨床的にP.salmonisに感染することを立証できた。この研究から、アースロバクターsp.nov.生ワクチンはP.salmonis感染に対して高度の防御を与えること及び防御効果が長期間であることが立証される。ワクチン中に死滅アースロバクター調製物を配合すると免疫促進効果が生じ、生残率が改善された。
