With eggs and children artemia were detedcted using nested-PCR. WSSV positive products could be detected in artemia, and DNA sequence of the product accords with the designed specific amplified one according to sequence analysis. The positive rates of wild brine shrimp and filial generation were 58% and 43%, respectively. However, it seems to be no regularity between parents and filial generations positive results. It may not judge whether WSSV could vertically transmit in artemia or not.

检测结果显示：卤虫中可扩增出特异性的、与引物设计吻合的DNA片段；DNA测序分析表明，扩增片段的DNA序列与白斑综合症病毒序列一致；野生卤虫携带白斑综合症病毒的阳性率为58％，实验条件下野生卤虫的后代的阳性率为43％；同一卤虫家系中，亲代与子代携带病毒的情况不完全一致，不能确定白斑综合症病毒可否通过繁殖在卤虫世代间进行垂直传播。
