| 摘要: |
| 以灭活的嗜水气单胞菌(Aeromonas hydrophila) 脂多糖和绣球菌(Sparasis crispa) 多糖作为免疫增强剂, 对接种免疫后的泥鳅(Misgurnusang uillicaudatus) 进行抗氧化性能、免疫功能及消化功能等指标进行测定。结果表明: 嗜水气单胞菌脂多糖和绣球菌多糖不仅可以提高泥鳅的抗氧化性能和免疫功能, 而且可以增强泥鳅的消化功能, 质量浓度为1 g/ L 的灭活嗜水气单胞菌脂多糖和9 g/ L 的绣球菌多糖对泥鳅的作用效果较明显, 能较明显地提高泥鳅抗氧化性能、免疫功能及消化功能, 与注射灭活的嗜水气单胞菌脂多糖相比,9 g/ L 绣球菌多糖对泥鳅的作用时间更持久。 |

| The effects of Aeromonas hydrophila-lipopolysaccharide and Sparasis crispa- polysaccharide on the immune and digestion function of loach(Misgurnusang uillicaudatus) |

| Abstract: |
| The lipopolysaccharides( LPS) of Aeromonas hydrophila and polysaccharide of Sparasis crispa were selected as immunopotentiators to challenge the loach Misgurnusang uillicaudatus respectively in the present paper. The indexes of antioxidation, immunity and ingestion were tested after challenging. The results indicted that the inactivated lipopolysaccharides of A. hydrophila and polysaccharide of S. crispa a could improve the functions of antioxidation, immunity and ingestion. Among the different densities the effects of 1 g/ L of inactivated A. hydrophila LPS and 9 g / L of S. crispa-polysaccharide were distinct. 1 g/ L of inactivated A. hydrophila LPS and 9 g / L of S. crispa-polysaccharide could improve the functions of antioxidation, immunity and ingestion. As contrast , the later affects longer than the former does. The result showed that they can be applied in the aquaculture of loach as the substitution of some antibiotics. |
