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

Phylogenomic evidence for host specialization and genetic divergence in OsHV-1 infecting Magallana gigas and Ostrea edulis

bioRxiv
Cross-species transmission is a major driver of disease emergence in humans and animals. The Ostreavirus ostreidmalaco1 (OsHV-1) is mainly associated with mortality in the Pacific oyster Magallana gigas, but has also been found in other mollusks ...

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 ...

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 ...

Experimental infection of Pacific oyster Crassostrea gigas spat by ostreid herpesvirus 1: demonstration of oyster spat susceptibility

Veterinary Research, 2011
In 2008 and 2009, acute mortalities occurred in France among Pacific cupped oyster, Crassostrea gigas, spat. Different hypothesis including the implication of environmental factors, toxic algae and/or pathogens have been explored.

Comparative Proteomics of Ostreid Herpesvirus 1 and Pacific Oyster Interactions With Two Families Exhibiting Contrasted Susceptibility to Viral Infection

Frontiers in Immunology, 2021
Massive mortality outbreaks affecting Pacific oysters (Crassostrea gigas) spat/juveniles are often associated with the detection of a herpesvirus called ostreid herpesvirus type 1 (OsHV-1). In this work, experimental infection trials of C.

Differential expression of novel metabolic and immunological biomarkers in oysters challenged with a virulent strain of OsHV-1 [PDF]

Developmental & Comparative Immunology, 2017
Early lifestages of the Pacific oyster (Crassostrea gigas) are highly susceptible to infection by OsHV-1 μVar, but little information exists regarding metabolic or pathophysiological responses of larval hosts. Using a metabolomics approach, we identified a range of metabolic and immunological responses in oyster larvae exposed to OsHV-1 μVar; some of ...

Vibrio Community Structure Shapes the Diversity of Carbenicillin‐Hydrolysing Class A β‐Lactamase Circulating in European Coastal Environments

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Vibrio communities shape carbenicillinase diversity in European coasts. Sediments serve as reservoirs of antibiotic‐resistant Vibrio alginolyticus, which can move into the water column and accumulate in bivalves. This spreads β‐lactamase resistance and raises human exposure risks to antibiotic‐resistant pathogenic Vibrio, especially as higher seawater ...

New Insight for the Genetic Evaluation of Resistance to Ostreid Herpesvirus Infection, a Worldwide Disease, in Crassostrea gigas.

PLoS ONE, 2015
The Pacific oyster, Crassostrea gigas, is the most important commercial oyster species cultivated in the world. Meanwhile, the ostreid herpesvirus 1 (OsHV-1) is one of the major pathogens affecting the Pacific oyster, and numerous mortality outbreaks ...
