Dynamic of the transcriptomic landscape of OsHV-1 replication in haemocytes of Pacific oyster

ABSTRACT Since the 1990s, the Pacific oyster ( Magallana gigas ) has experienced repeated mortality events associated with Ostreid herpesvirus 1 (OsHV-1). Although the virus has been genomically characterised, its replication cycle and its interactions with the oyster immune system ...

Shedding of OsHV-1 from infected Pacific oysters depends on viral variant

Philosophical Transactions B
Abstract Ostreid herpesvirus-1 (OsHV-1) can cause massive economic losses of Pacific oysters, Magallana gigas. Breeding resistant oysters in the USA is difficult owing to lack of oyster hatcheries within disease-endemic locations. Without resistant oysters, understanding transmission dynamics is useful to assess the risk of disease ...

Mortality associated with OsHV-1 in spat Crassostrea gigas: role of wild-caught spat in the horizontal transmission of the disease

, 2014
The French oyster production of Crassostrea gigas is based on two sources of spat: wild-caught (WC) and hatchery-produced (HP). Massive mortality related to the ostreid herpesvirus type 1 (OsHV-1) has affected both sources in France since 2008.

Antiviral protection in the Pacific oyster Crassostrea (Magallana) gigas against OsHV-1 infection using UV-inactivated virus

Frontiers in Marine Science
The increase of the frequency and severity of marine diseases affecting farmed marine mollusks are currently threatening the sustainability of this aquaculture sector, with few available prophylactic or therapeutic solutions.

Interaction between toxic dinoflagellate Alexandrium catenella exposure and disease associated with herpesvirus OsHV-1 in Pacific oyster spat Crassostrea gigas.

, 2015
International audienceBlooms of toxic dinoflagellates can co-occur with mass mortality events associated with herpesvirus OsHV-1 μVar infection that have been decimating Pacific oyster Crassostrea gigas spat and juveniles every summer since 2008 in ...

Temperature and microbe mediated impacts of the San Diego Bay ostreid herpesvirus (OsHV-1) microvariant on juvenile Pacific oysters

The ostreid herpesvirus (OsHV-1) was recently detected in San Diego Bay for the first time in farmed juvenile Pacific oysters (Crassostrea gigas). Due to the virus’ ability to cause mass mortality (50 to 100%), it is important to determine the factors ...

Short Technical Report for OsHV-1 detection and quantification by Real Time Polynerase Chain Reaction using OsHV-1 DNA polymerase sequence

, 2013
The present report completes a previously described procedure routinely used for the detection and quantification of OsHV-1 by Sybr green Real Time Polymerase Chain Reaction targeting the OsHV-1 DNA polymerase sequence. More particularly, this document brings information about analytical sensitivity, quantitation limit, assay precision, reproducibility

Detection of Latent OsHV-1 Infection in West Coast Oysters Post Temperature Stress

OsHV-1 is a pathogen of commercially valuable Pacific Oyster, Crassostrea Gigas. In recent years mass mortality events have wiped out large quantities of oysters in farms, and this mortality has been associated with OsHV-1.
