AB  - Early detection of Pacific oyster spat infected with ostreid herpesvirus 1 
      (OsHV-1) could prevent introduction of OsHV-1-infected individuals into farming 
      areas or onshore rearing facilities, thus reducing the risk of infection of naive 
      oysters in such production systems. Experiments were conducted on several hundred 
      oyster spat provided by producers in order to examine whether early rearing 
      practices could be considered as potential risk factors for (1) OsHV-1 infection 
      as detected by molecular methods and (2) spat mortality experimentally induced 
      through thermal challenge. Spat groups collected on oyster beds and hatchery spat 
      reared in growout areas during summer exhibited higher viral DNA contamination 
      and mortalities during the trial than spat kept in onshore rearing facilities. 
      Quantification of viral DNA before and during the trial showed that infection 
      prevalence and intensity changed over time and revealed latent infection 
      initially unsuspected in 3 of 10 groups. Thermal challenge induced a clear 
      increase in the probability of detecting infected individuals, particularly for 
      groups exhibiting significant prevalence of OsHV-1-contaminated spat prior to the 
      challenge. The use of detection methods are discussed in relation to early 
      rearing practices and disease control strategies.
