从海南养殖卵形鲳致病嗜麦芽假单胞菌细胞壁中提取脂多糖 ,分别用一次腹腔注射免疫法、加强腹腔注射免疫法和口服法对健康卵形鲳进行免疫接种 ,结果表明 ,以这 3种方法接种脂多糖 2～ 12周 ,实验鱼类对嗜麦芽假单胞菌的血清凝集抗体效价及其对嗜麦芽假单胞菌病的抵抗力均有显著提高。此外 ,卵形鲳在接种嗜麦芽假单胞菌脂多糖后 ,其血液中白细胞的吞噬活性也有明显增加
Lipopolysaccharide (LPS) was extracted from the cell wall of Pseudomonas maltophilia by culturing ovipositing in Hainan, and immunized with one intraperitoneal injection and immunization by oral intraperitoneal injection and oral method respectively. The results showed that, The three methods of inoculation of lipopolysaccharide for 2 to 12 weeks, the experimental fish on the titer of serum-agglutinating antibodies of Pseudomonas maltophilia and its resistance to Pseudomonas maltophilia were significantly increased. In addition, oocysts after inoculation of Pseudomonas malt lipopolysaccharide, the phagocytic activity of leukocytes in the blood also increased significantly
