自其分子特征，牡蛎疱疹病毒1型（OsHV-1）已定期在法国太平洋牡蛎中检测到。虽然它的致病性在幼虫阶段得到证实，但它在幼虫阶段的死亡率爆发期间的参与受到高度怀疑，但没有证据。为了调查死亡率爆发，法国国家软体动物健康监测和监测网络（REPAMO）在青少年中进行了两次调查。千兆。第一次调查从1998年持续到2006年，是一次流行病学调查，当时牡蛎养殖户报告了死亡率爆发。第二次调查是纵向调查，于1998年开始，以完成对OsHV-1的网络观测。数据分析显示了与OsHV-1检测相关的死亡率爆发的特定模式。Ostreid herpesvirus 1的检出主要出现在夏季，表明海水温度对其发生有影响。田间多呈斑块状分布，苗圃则相反。OsHV-1的检测和贝苗死亡率之间的显着关系被发现，优先在庇护和封闭的环境。纵向调查证实了大多数网络观察结果。尽管后续的工作，特别是流行病学调查将有助于确认OsHV-1的检测与青少年C. gigas，OsHV-1在牡蛎死亡中的作用正在研究中。
Since its molecular characterisation, Ostreid herpesvirus 1 (OsHV-1) has been regularly detected in Crassostrea gigas in France. Although its pathogenicity was demonstrated on larval stages, its involvement during mortality outbreaks at the juvenile stage was highly suspected but not evidenced. To investigate mortality outbreaks, the French National Network for Surveillance and Monitoring of Mollusc Health (REPAMO) carried out two surveys in juvenile C. gigas. The first survey lasted from 1998 to 2006 and was an epidemiological inquiry occurring when oyster farmers reported mortality outbreaks. The second survey, a longitudinal one, was set up in 1998 to complete the network observations on OsHV-1. Data analysis showed a specific pattern of mortality outbreaks associated with OsHV-1 detection. Ostreid herpesvirus 1 detection mainly appeared during the summer, suggesting the influence of the seawater temperature on its occurrence. It mostly presented a patchy distribution in the field in contrast to the nursery. Significant relationship between OsHV-1 detection and spat mortality was found, preferentially in sheltered and closed environments. The longitudinal survey confirmed most of the network observations. Although subsequent works particularly epidemiological surveys would be useful to confirm the causal link between the detection of OsHV-1 and the mortality outbreaks in juvenile C. gigas, the role of OsHV-1 in oyster mortality is progressing.
