鱼肠道弧菌免疫检测方法的研究

采用灭活的鱼肠道弧菌作为抗原,制备兔抗血清,建立了鱼肠道弧菌的间接荧光抗体检测技术(indirect im-munofluorescence assay test,IFAT)、Western-blotting免疫印迹检测技术。IFAT结果显示阳性信号覆盖整个菌体,明亮,清晰,荧光信号呈长弧形且两端钝圆,与鱼肠道弧菌形状一致。Western-blotting结果显示共10条蛋白带发生免疫反应,其中6条蛋白带结果较清晰,显示出较强的特异性免疫反应,阴性对照组无条带。IFAT和Western-blotting结果说明所建立检测方法能够准确、快速的检测出鱼肠道弧菌。

Preparation of Adjuvant Diluent for Live Vaccine against Classical Swine Fever and Evaluation of its Immune Effects

The aim of this study was to develop a novel oil-in-water (O/W) emulsion as adjuvant diluents (AD) for live vaccine against classical swine fever (CSF) that could effectively enhance the immune effect of vaccine.The AD was prepared by high-pressure homogenization technique.Formulations and preparation parameters were optimized with response surface design.Its stability, particle size, polydispersity (PDI) and Zeta potential were characterized.The humoral immune response and cellular immune response of the AD were evaluated with BALB/c mice by intramuscular injection.The particle size of the AD prepared by optimized formulation and parameters was 100.4 nm, PDI was 0.147, and Zeta potential was —28.7 mV.The experiment results showed that the AD had good stability.The AD was inoculated combined with live vaccine against CSF into BALB/c mice by intramuscular injection.The results showed that the live vaccine against CSF specific immune responses could be evoked in mice by co-inoculation with AD and vaccine.The cellular immune response levels in co-inoculated groups were significantly higher than control group (P<0.05), with obvious phenomena of higher levels of IFN-γ, IL-6 and IL-4 in serum.The result revealed that cellular immune capability significantly improved with the AD.The results strongly revealed that cellular immune capability significantly improved by introducing AD for effective immune-adjuvant for live vaccine against CSF.
