| 摘 要： | 以编码II型GCRV VP5和NS38的B细胞线性表位的cDNA串联构建pcDNA3.1(+)-Bs5-10（GenBank登录号为MH234474），并包被成纳米级壳聚糖颗粒；无GCRV草鱼（11~12 cm、25~30 g）随机分为空白对照组、空白对照-GCRV攻毒组、裸空载体注射组、壳寡糖包被空载体口服组、裸DNA疫苗注射组（每尾鱼注射10 μg载体，1 d和29 d各免疫1次）、壳寡糖包被DNA疫苗口服组（每尾鱼大约投喂50 μg载体，1～3 d、15～17 d和43～45 d各口服免疫1次），在28℃水温下评价疫苗保护力和特异性抗体水平。结果显示，裸DNA疫苗注射组和壳寡糖包被DNA疫苗口服组的相对保护率分别为66.67%和50%；两组血清抗VP5和抗NS38的IgM水平均随加强免疫而显著升高（P<0.05）；且在对应时间点（22 d或50 d），前组特异性IgM水平均显著高于后者（P<0.05）。结果表明，壳聚糖包被的DNA疫苗口服免疫能在一定程度上抵抗GCRV攻击，且体液免疫参与了该保护机制。
