检测细菌多糖对草鱼的免疫调节作用。用酚水法分别从大肠杆菌和根癌农杆菌细胞壁中提取出粗多糖,注射草鱼,测定受试草鱼血液中白细胞数量,血清中抗体效价,肝脏、肾脏、脾脏、血清和粘液中过氧化物酶的活力。结果受试草鱼中的白细胞数量、血清抗体效价及过氧化物酶活力均具有明显提高。结论表明大肠杆菌和根癌农杆菌粗多糖对草鱼有免疫促进作用。
Detection of bacterial polysaccharides on the immune regulation of grass carp. Crude polysaccharides were extracted from the cell wall of Escherichia coli and Agrobacterium tumefaciens respectively by phenol-water method. Grass carp was injected to test the blood leukocyte count, antibody titer in serum, peroxidation in liver, kidney, spleen, serum and mucus Enzyme activity. Results The number of white blood cells, serum antibody titer and peroxidase activity in grass carp were significantly increased. The results showed that E. coli and Agrobacterium tumefaciens crude polysaccharides had an immune promoting effect on grass carp.
