Abstract

A comparative study of some parameters of nonspecific immunity in the Angelinskii rubella-resistant variant of the scaly and mirror groups of carp in the prespawning and late feeding periods was carried out. The level of the antimicrobial properties of the C-reactive protein, nonspecific immune complexes in the blood serum, and phagocytic activity of neutrophils were studied. The study showed interbreed and inter-seasonal differences in some indicators. It is concluded that the higher level of bacteriostatic activity of blood serum in the rubella-resistant variant, compared with other groups of carp, provides a low percentage of immunodeficient individuals and resistance to pathogens of infectious diseases.

不同年循环时期鲤鱼各养殖群非特异性免疫的若干指标

摘要

对产卵前和摄食后期鲤鱼鳞状和镜状组的Angelinskii风疹抗性变种的一些非特异性免疫参数进行了比较研究。研究了C反应蛋白的抗菌特性水平、血清中的非特异性免疫复合物和嗜中性粒细胞的吞噬活性。该研究显示了一些指标的杂交和季节间差异。得出的结论是，与其他鲤鱼群体相比，抗风疹变异体血清的抑菌活性水平更高，提供了较低百分比的免疫缺陷个体和对传染病病原体的抵抗力。
