![]() Summer mortalities and detection of ostreid herpesvirus microvariant in Pacific oyster Crassostrea gigas in Sweden and Norway.Detection and description of a particular Ostreid herpesvirus 1 genotype associated with massive mortality outbreaks of Pacific oysters, Crassostrea gigas, in France in 2008.Variants of herpetic virus ostreid herpesvirus-1 (OsHV-1) in young Pacific oyster Crassostrea gigas.Detection of undescribed ostreid herpesvirus 1 (OsHV-1) specimens from Pacific oyster, Crassostrea gigas.Ostreid herpesvirus OsHV-1 μVar in Pacific oysters Crassostrea gigas (Thunberg 1793) of the Wadden Sea, a UNESCO world heritage site.Experimental infection of Pacific oyster Crassostrea gigas spat by ostreid herpesvirus 1: demonstration of oyster spat susceptibility.Detection of different variants of Ostreid Herpesvirus 1 in the Pacific oyster, Crassostrea gigas between 20.Experimental ostreid herpesvirus 1 infection of the Pacific oyster Crassostrea gigas: kinetics of virus DNA detection by q-PCR in seawater and in oyster samples.In situ hybridization and histopathological observations during ostreid herpesvirus-1-associated mortalities in Pacific oysters Crassostrea gigas.L2 - rfr_id=ori:rid:&rfr_dat=cr_pub=pubmed During this period, the water temperature was below 16☌. An initial increment in the number of PCR-positive oysters was reported at both field sites during the survey in the absence of significant mortality. Mass mortality was observed among oysters a few days after increases in the number of PCR-positive oysters and viral-DNA amounts were recorded. This difference may be related to earlier increases in water temperature. Although similar massive mortality rates were reported at the 4 sites, mortality was detected earlier in the pond and in the nursery than at both field sites. Mortality rates were recorded based on regular observation, and samples were collected to search for and quantify OsHV-1 DNA by real-time PCR. For this purpose, a single batch of Pacific oyster spat was deployed in 4 different locations in the Marennes-Oleron area (France): an oyster pond ("claire"), a shellfish nursery, and two locations in the field. Additional data are necessary to better describe mortality events in relation to environmental-parameter fluctuations and OsHV-1 detection. ![]() gigas in Europe have been related to the detection of a variant of OsHV-1 called μVar. Since 2008, mass mortality outbreaks among C. This virus has been classified as Ostreid herpesvirus 1 (OsHV-1) within the family Malacoherpesviridae. A particular herpesvirus was purified from naturally infected larval Pacific oysters, and its genome was completely sequenced. N2 - A number of bivalve species worldwide, including the Pacific oyster, Crassostrea gigas, have been affected by mass mortality events associated with herpesviruses, resulting in significant losses. JF - Applied and environmental microbiology T1 - Ostreid herpesvirus 1 infection among Pacific oyster (Crassostrea gigas) Spat: relevance of water temperature to virus replication and circulation prior to the onset of mortality. ![]() ![]() A number of bivalve species worldwide, including the Pacific oyster, Crassostrea gigas, have been affected by mass mortality events associated with herpesviruses, resulting in significant losses.
