白斑综合症病毒 (WSSV)对斑节对虾 (Penaeusmonodon)亲虾的致病力强 ,其致病性特征与对未成熟个体的致病性特征相同 ;经WSSV感染的斑节对虾亲虾的死亡率为 10 0 % .感染了WSSV的亲虾的PCR检测结果均呈阳性 ,组织切片观察可见到明显的组织病变 ,电镜观察发现病变组织 (包括卵巢 )的细胞内有大量病毒粒子 ;原位杂交结果证明 ,患白斑综合症的斑节对虾亲虾的卵巢中不仅卵母细胞感染上病毒 ,卵细胞也感染上了病毒 .这些结果表明 ,WSSV在斑节对虾中具备垂直传播的条件 .
White spot syndrome virus (WSSV) is very virulent to penaeus monodon (Penaeus monodon) broodstock and has the same pathogenicity as the virulence of unripe individuals; the death of Penaeus monodon The rate was 10% .The WSSV infected broodstock PCR test results were positive, obvious histological lesions can be seen by tissue section observation, electron microscopy found a large number of virus particles in the diseased tissue (including the ovary); in situ hybridization The results demonstrate that not only the oocytes in the ovary of Penaeus monkshood infected with white spot syndrome are infected with the virus and the eggs are infected with the virus, these results indicate that WSSV has vertical transmission in M. monodon.
