For the investigation of anti-infection immune response of Pseudosciaena crocea, 160 healthy fish samples were categorized into infected and control groups. Each individual fish in the infected group was
injected intraperitoneally (i.p.) with 0.2 ml bacterial suspension of Vibrio alginolyticus in density of 2×107 CFU/ml, while each individual in the control group was injected i.p. with 0.2 ml sterile saline solution (0.85%). It was
observed that the artificial injection of V. alginolyticus significantly increased the number of erythrocytes, leucocytes, lymphocytes in peripheral blood as well as peripheral serum
antibacterial activity and antibody titer of large yellow croaker, and significantly reduced the number of peripheral blood
granulocytes as compared with those in the control group. No significant difference in acid phosphytase and superoxide dismutase
activity of serum was detected between the two groups. It is suggested that non-specific immune factors including leucocytes
and anti-bacteria substance in peripheral blood played important role at the initial stage of infection, and specific immune
factors such as antibody then played important role in response to anti-infection at the latter stage.

Non-specific immune response of bullfrog Rana catesbeiana to pathogenic Aeromonas hydrophila was studied to 60 individuals in two groups.Each bullfrog in bacterium-injected group was injected intraperitoneally(i.p.) with 0.2 ml bacterial suspension at a density of 5.2 × 106 CFU/ml,while each one in control group injected i.p.with 0.2 ml sterile saline solution(0.85%,w/v).Three bullfrogs in both groups were sampled at 0,1,3,7,11,15 and 20 days post-injection(dpi) for the evaluation of non-specific immune parameters.It was observed that intraperitoneal injection of A.hydrophila significantly increased the number of leucocytes and that of NBT-positive cells in peripheral blood.Significant increases in serum bactericidal activity and serum acid phosphatase activity were also observed in the bacterium-injected frogs when compared with those in the control group.However,a significant reduction was detected in vitro in phagocytosis activity of peripheral blood phagocytes.No significant difference in changes in the number of peripheral erythrocytes,serum superoxide dismutase(SOD) activity,and lysozyme activity was detected between the two groups.It is suggested that bullfrogs may produce a series of non-specific immune reactions in response to the A.hydrophila infection. 相似文献

区域概况沧州市地处河北省东部,黑龙港流域游,共辖16个县(市)、两个农场,总面积14051km2,耕地1180万亩,总人口640万。是河北水资源最紧缺的地市之一。由于地表水源不足,工农业生产主要依靠地下水。近十年来,全市年均开采地下水96亿m3,深层水平均超采近2亿m3,造成地下水位 相似文献
