摘要
采用2．0％和3．5％PEG沉淀法，研究了鲫鱼、草鱼、鳙鱼、鲶鱼和罗非鱼血清免疫复合物。统计结果表明，免疫复合物含量在同一鱼类的不同PEG浓度处理间均有显著差异；在不同鱼类的同一PEG浓度处理间，除鳙鱼和鲶鱼间无显著差异外，其余均有显著差异。实验发现，血清免疫复合物的含量变化与各种淡水鱼在分类上的地位及抗病能力明显相关。
with a PEG spectrophotometric method, circulating immune complexes of crucian carp, grass carp , variegated carp, catfist, and Africa crucian carp were determined. It was found that there were significantly differences in levels between the two PEG rteatment of each of five freshwater fishes. There also existed differences in levels among five fresh freshwater water fishes but varigeated caup and catfish in both concentrations of PEG. These findings suggest that the amounts of circulating immune complexes of freshwater fishes are associated with their classificatory position and ability of disease-resistant . It is thonght, therefore, the ability of neutralizing antigens in freshwater fishes are affected not only by their classificatory position but also by their abiliby of disease-resistant.
