Antiviral Defense and Innate Immune Memory in the Oyster

Viruses, 2018
The Pacific oyster, Crassostrea gigas, is becoming a valuable model for investigating antiviral defense in the Lophotrochozoa superphylum. In the past five years, improvements to laboratory-based experimental infection protocols using Ostreid herpesvirus

Size and genotype affect resistance to mortality caused by OsHV-1 in Crassostrea gigas [PDF]

Aquaculture, 2013
As with summer mortalities reported in France between 2001 and 2006, mortality caused by the Ostreid herpesvirus 1 (OsHV-1) in Crassostrea gigas affects mostly juveniles, although adults can also be impacted to a small extent. This could suggest that both mortalities have similar causes and that establishment of resistance, in particular to the Ostreid

Experimental infections of Pacific oyster Crassostrea gigas using the Australian OsHV-1 µVar strain [PDF]

, 2015
In Australia the spread of the Ostreid herpesvirus OsHV-1 microvariant (OsHV-1 µVar) threatens the Pacific oyster industry. There was an urgent need to develop an experimental infection model in order to study the pathogenesis of the virus in controlled ...

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 ...

CgMyD88s Serves as an Innate Immune System Plug During Ostreid Herpesvirus 1 Infection in the Pacific Oyster (Crassostrea gigas)

Frontiers in Immunology, 2020
Ostreid herpesvirus-1 microvariant (OsHV-1 μVar) is considered a major infectious microbe that can reduce the survival of natural or cultured oysters in summer.

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 ...

Coculture with Eastern oysters is unlikely to reduce OsHV-1 impacts to farmed Pacific oysters: A modelling approach

Aquaculture Reports
In recent decades, the global expansion of Pacific oyster Magallana gigas aquaculture, driven by this species’ adaptability and rapid growth, has coincided with the emergence of novel and virulent microvariants (muvars) of Ostreid herpesvirus 1 (OsHV-1),

Factors influencing disease-induced mortality of Pacific oysters Crassostrea gigas

Aquaculture Environment Interactions, 2015
Mortalities of oyster Crassostrea gigas seed associated with ostreid herpesvirus OsHV-1 μVar have been observed in many oyster-producing countries since 2008.

Scientific Opinion on the increased mortality events in Pacific oysters, Crassostrea gigas

EFSA Journal, 2010
In the summer of 2008 and 2009, severe mortality events in cultured Pacific oyster were reported from the main European producing countries. The European Commission requested EFSA to assess the relative importance of possible causes, including infectious
