- a feed control group to which no acid heat-treated cells were added was used.
- Infectious diseases caused by WSSV are infectious diseases caused by viruses that have spread worldwide since 1990 and have caused enormous damage to shrimp farming. It also occurred in Japan for the first time in a region where Chinese prawn seedlings were introduced in 1993, and spread to western Japan the following year, causing serious damage to the prawn aquaculture industry. It is the most important infectious disease in shrimp farming because of high mortality and infection rate.
- Test Method 5 Infection preventive effect in the prawn WSSV infection model 5-1.
- Feeding method As test animals, 40 prawns (weight approximately 18 g) were reared in a 200 L water tank. 0.2, 0.5, or 1.0% by weight of acidic heat-treated cells were added to feed materials such as fish meal, minerals, and vitamins, and 10% by weight of water was added and kneaded thoroughly. Then, after granulating using a fine disc pelleter, it was dried in a heat dryer at 40 ° C. for 10 hours to prepare a shrimp feed to which acidified heat-treated cells were added. Moreover, the feed which does not add an acidic heat processing microbial cell as a control plot was produced. These feeds were orally administered to each test group from 7 days before the test start date (WSSV infection date) to 15 days after the test start. The dose in each test group corresponds to 0, 20, 50, or 100 mg / kg body weight per day as the amount of cells.

- Beggar is a biological defense mechanism of the innate immune system that exists in common from higher organisms such as mammals to lower organisms such as invertebrates. Specifically, phagocytic cells such as macrophages and neutrophils remove foreign substances from the body by taking in foreign substances that have entered. In general, it is said that an immunostimulatory substance such as peptidoglycan exhibits an immunostimulatory effect by improving phagocytic ability, and serves as an index for evaluating the immunostimulatory substance. In prawns belonging to the crustacean, cells called macrophages and neutrophils do not exist, and blood cells play a similar role.
- Test method 7 Phagocytosis in prawn blood cell 7-1. Rearing of prawns As test animals, prawns (about 18 g) were reared in a 60 L aquarium with 15 fish in each test area.
- Feeding method 0, 0.2, 0.5, or 1.0% by weight of acidic heat-treated cells were added to feed materials such as fish meal, minerals, and vitamins, and 10% by weight of water was added and kneaded sufficiently. Then, after granulating using a fine disc pelleter, dried with a heat dryer at 40 ° C. for 10 hours to prepare a shrimp feed to which acidic heat-treated cells were added. This feed was fed for 23 days.
- the dosage of acidic heat-treated cells is an amount corresponding to 0, 20, 50, or 100 mg / kg body weight per day, respectively.
- Phagocytosis Blood was collected from 5 each of prawns before and 3 days and 7 days after the start of administration of the test feed, and granulocytes were separated by percoll density gradient centrifugation. 200 ⁇ L of the suspension was spread on a cover glass in a plastic petri dish and blood cells were attached, and then 2 mL of yeast suspension was added and cultured for 2 hours. After completion of the culture, the cells were fixed with a fixing solution and then stained with a light solution and observed under a microscope.
- Example 8 Evaluation of phagocytic ability using prawn blood cells by acidic heat-treated E. coli cells
- Test method 8 In the same manner as in Example 6, acid heat treatment was performed on fermentation by-product cells of E. coli (hereinafter referred to as acid heat-treated E. coli cells), and phagocytic ability was evaluated by exactly the same method as Test Method 7. It was. As test groups, four test groups were prepared in which the amount of acidic heat-treated E. coli cells was 0, 20, 50, or 100 mg / kg body weight per day. The test results are shown in Table 10.
- Example 9 Infectious disease preventive effect in Japanese flounder farm As in Example 1, heat treatment was performed under mild acidity (pH 4) on fermentation by-product cells of Corynebacterium glutamicum (Ajinomoto Indonesia AJITEIN) Using the microbial cells (acid heat-treated microbial cells) obtained by carrying out (105 ° C., 2 hours), the infectious disease prevention effect in the flounder farm was confirmed in the manner of Test Method 7.
- Test method 9 Flounder field test 9-1. About the test farm The field test was conducted at the farm in Nagato City, Yamaguchi Prefecture for two months from July 1, 2011 to August 31, 2011. In addition, this aquaculture farm performs a complete aquaculture, and raises the seawater directly and the breeding water is a pouring type.
- Test animals 2000 flounder (weight approximately 80 g) were used for the field test in both the test and target groups.

1-1.パイエル板の採取及び細胞液の調製
マウスを剖検し、小腸を摘出した。摘出した小腸から湾曲眼科鋏などを用いてパイエル板を採取した。パイエル板からセルストレーナー(ベクトンディッキンス社製)を用いて単細胞浮遊液を調製し、遠心分離により単細胞を集積し、10 %牛胎児血清添加RPMI1640培地に懸濁させた。
細胞懸濁液中の生細胞数をトリパンブルー染色で計測し、細胞数を1×105個/mL~1×106個/mLに調整して、96穴の細胞培養用マイクロプレートに200μLずつ分注した。PBS緩衝液で、2000μg/ml及び80μg/mlに濃度調製した加熱処理菌体サンプル溶液、又は陰性対照としてのPBS緩衝液をそれぞれ5 μLずつ分注して、5日間、37℃、5% CO2の条件下で培養した。陽性対照として、5μg/mlとなるようにPBSに懸濁させたLPS(E. coli由来リポ多糖;シグマ社製)を用いた。

細胞懸濁中の生細胞数をトリパンブルー染色で計測した。細胞数を2×106個/mLに調整して、96穴の細胞培養用マイクロプレートに100μLずつ分注した。10 % FCS添加RPMI1640培地で2000μg/ml及び80μg/mlに濃度調製した加熱処理菌体サンプル溶液をそれぞれ100 μLずつ分注して、7日間、37℃、5% CO2の条件下で培養した。陽性対照として、5μg/mlとなるように10 % FCS添加RPMI1640培地に懸濁させたLPS(E. coli由来リポ多糖;シグマ社製)を用いた。
培養終了後に、培養上清中のIL-12濃度をELISAキットを用いて測定した。なお、測定は2回実施し平均値を求めた。
試験法1、及び試験法2のいずれにおいても、酸性条件で免疫賦活活性が亢進した。免疫賦活活性の亢進は、pH 2、及びpH6でも観察されたが、特にpH 3~5で顕著であった。
実施例1と同様に、副生乾燥菌体を蒸留水に10重量%となるように添加し十分懸濁させた。硫酸を用いて、この菌体懸濁液のpHを4に調製した後、電気オートクレーブを用いて90℃、105℃、120℃の3条件で、各2時間加熱し、各温度の酸加熱処理菌体サンプルを調製した。このサンプルについて前記試験法1及び2にて免疫賦活活性を調べた。結果を表3及び表4に示す。
発酵副生菌体に対し、実施例1と同様に、弱酸性下(pH 4)で加熱処理(105℃、2時間)を行なって得たサンプル(以下、「酸性加熱処理菌体;試験区I」)と、加熱処理を行なわないで得たサンプル(以下、「非処理菌体;試験区II」)について、下記試験法3で示した試験法によりマウスへの細菌感染予防効果を調べた。対照として菌体の代わりに生理食塩水を投与した群(陰性対照、対照区I)と、抗生物質ビコザマイシン(シェリングプラウ・アニマルヘルス社製。商品名:バクテロン)400mg/kgを投与した群(陽性対照、対照区II)、及び非感染区(生理食塩水投与;対照区III)を用いた。

試験飼料給与開始前、投与開始3日後および7日後に各5匹ずつのクルマエビから採血を行い、パーコール密度勾配遠心法により顆粒球細胞を分離した。その懸濁液200 μLをプラスチックシャーレ中のカバーガラスに広げ、血球細胞を付着させたのち、酵母懸濁液2 mLを加えて2時間培養した。培養終了後、固定液で固定後にライト液で染色を行い顕微鏡下で観察した。
血球細胞の酵母貪食率((酵母貪食血球細胞数 / 観察血球細胞数) ×100)、1血球細胞あたりの酵母取り込み数(血球細胞に貪食された酵母総数/観察血球細胞数)および貪食指数((酵母貪食血球細胞数/観察血球細胞数)×1血球細胞あたりの酵母取り込み数×100)により評価を行った。試験結果は表9に示す。
実施例6と同様にして、E. coliの発酵副生菌体について酸性加熱処理を行い(以下、酸性加熱処理E. coli菌体)、試験法7と全く同じ方法により貪食能の評価を行った。試験区には、酸性加熱処理E. coli菌体の投与量が1日あたり、0、20、50、又は100 mg/体重kgの4試験区を用意した。試験結果は表10に示す。
