Genomic Diversity of the Ostreid Herpesvirus Type 1 Across Time and Location and Among Host Species

Frontiers in Microbiology, 2021
The mechanisms underlying virus emergence are rarely well understood, making the appearance of outbreaks largely unpredictable. This is particularly true for pathogens with low per-site mutation rates, such as DNA viruses, that do not exhibit a large ...

Effect of water temperature on mortality of Pacific oysters Crassostrea gigas associated with microvariant ostreid herpesvirus 1 (OsHV-1 µVar)

Aquaculture Environment Interactions, 2016
The ostreid herpesvirus 1 microvariant (OsHV-1 µVar) causes mass mortality of Pacific oysters Crassostrea gigas. Water temperature can directly influence the incidence of disease or correlate with seasonal changes in the environment and oyster physiology

ADAR-Editing during Ostreid Herpesvirus 1 Infection in Crassostrea gigas: Facts and Limitations

mSphere, 2022
Ostreid herpesvirus-1 (OsHV-1) RNAs are enzymatically modified by A-to-I conversions during the infection of Crassostrea gigas. The increase of ADAR1 expression and hyper-editing activity parallel to OsHV-1 RNAs suggests a functional connection between ...

Rapid capture and detection of ostreid herpesvirus-1 from Pacific oyster Crassostrea gigas and seawater using magnetic beads. [PDF]

PLoS ONE, 2018
Ostreid herpesvirus-1 (OsHV-1) has been involved in mass mortality episodes of Pacific oysters Crassostrea gigas throughout the world, causing important economic losses to the aquaculture industry.

Impact of seawater temperature on the Pacific oyster (Crassostrea gigas) microbiome and susceptibility to disease associated with Ostreid herpesvirus-1 (OsHV-1) [PDF]

, 2022
Context: Intertidal estuarine environments expose oysters to wide temperature variations. This can shift their microbiome composition towards pathogen-dominated communities. Understanding the impact of temperature on the microbiome will facilitate oyster

Effect of air exposure, handling stress and imidacloprid on the susceptibility of Crassostrea gigas to Ostreid herpesvirus 1 (OsHV-1)

Aquaculture Environment Interactions, 2019
The emergence of the microvariant genotype of Ostreid herpesvirus 1 (OsHV-1 μVar) has caused mass mortalities of Pacific oysters Crassostrea gigas, resulting in significant economic losses in Europe, New Zealand and Australia. There is variability in the

Parallel analysis of miRNAs and mRNAs suggests distinct regulatory networks in Crassostrea gigas infected by Ostreid herpesvirus 1

BMC Genomics, 2020
Background Since 2008, the aquaculture production of Crassostrea gigas was heavily affected by mass mortalities associated to Ostreid herpesvirus 1 (OsHV-1) microvariants worldwide.

QTL for resistance to summer mortality and OsHV‐1 load in the Pacific oyster (Crassostrea gigas) [PDF]

Animal Genetics, 2010
SummarySummer mortality is a phenomenon severely affecting the aquaculture production of the Pacific oyster (Crassostrea gigas). Although its causal factors are complex, resistance to mortality has been described as a highly heritable trait, and several pathogens including the virus Ostreid Herpes virus type 1 (OsHV‐1) have been associated with this ...

Oyster mortality

EFSA Journal, 2015
This updated scientific opinion on oyster mortality addresses 1) the role of ostreid herpesvirus (OsHV‐1) in mortality, 2) evidence for a role of Vibrio aestuarianus in mortality, 3) effectiveness of water treatment in inactivating OsHV‐1 and V ...
