Ostreid herpesvirus 1 (OsHV-1) detection among three successive generations of Pacific oysters (Crassostrea gigas).

Ostreid Herpesvirus 1 (OsHV-1) was likely detected in Pacific oysters, Crassostrea gigas, at different stages of development. Viral infections were associated with high mortality rates in the spat and larvae. Furthermore, the persistance of OsHV-1 in asymptomatic adults was demonstrated by detection of viral DNA and proteins. In the present study, three successive generations of C. gigas (G0 an...

Detection of Ostreid Herpesvirus 1 (OsHV-1) DNA in seawater by PCR: influence of water parameters in bioassays.

Since 1991, herpesvirus infections have been reported among larvae and juveniles of various bivalves. Most of the studies focused on detection of viral infections of economically important species. However, the persistence of bivalve herpesviruses in the marine environment is poorly documented. The present study concerns the role of seawater parameters in Ostreid Herpesvirus 1 (OsHV-1) detectio...

Rearing practices identified as risk factors for ostreid herpesvirus 1 (OsHV-1) infection in Pacific oyster Crassostrea gigas spat.

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 naïve oysters in such production systems. Experiments were conducted on several hundred oyster spat provided by producers in order to examine whether early rearing pr...

Metabolism of the Pacific oyster, Crassostrea gigas, is influenced by salinity and modulates survival to the Ostreid herpesvirus OsHV-1

The Pacific oyster, Crassostrea gigas, is an osmoconforming bivalve exposed to wide salinity fluctuations. The physiological mechanisms used by oysters to cope with salinity stress are energy demanding and may impair other processes, such as defense against pathogens. This oyster species has been experiencing recurrent mortality events caused by the Ostreid herpesvirus 1 (OsHV-1). The objective...

French scallops: a new host for ostreid herpesvirus-1.

Sporadic high mortalities were reported among larval French scallops (Pecten maximus). Electron microscopy of moribund larvae revealed particles with the characteristics of a herpesvirus in association with cellular lesions. PCR and DNA sequencing showed that the virus is a variant of ostreid herpesvirus-1 that has already been described in clams and oysters. This is the first description of a ...
