OsHV-1 countermeasures to the Pacific oyster's anti-viral response [PDF]

Fish & Shellfish Immunology, 2015
The host-pathogen interactions between the Pacific oyster (Crassostrea gigas) and Ostreid herpesvirus type 1 (OsHV-1) are poorly characterised. Herpesviruses are a group of large, DNA viruses that are known to encode gene products that subvert their host's antiviral response.

Effect of ploidy on the mortality ofCrassostrea gigasspat caused by OsHV-1 in France using unselected and selected OsHV-1 resistant oysters [PDF]

Aquaculture Research, 2014
The effect of ploidy on the mortality of Crassostrea gigas spat caused by the ostreid herpesvirus (OsHV-1) genotype μVar was investigated at five sites along the Atlantic coast in France in 2011. Sibling diploids and triploids were produced using either unselected or selected OsHV-1-resistant oysters.

Plankton and marine aggregates as transmission vectors for V. aestuarianus 02/041 infecting the pacific oyster Crassostrea gigas

Environmental Microbiology Reports, Volume 15, Issue 6, Page 631-641, December 2023., 2023
Using controlled infection experiments this study provides evidence that incorporation into marine planktonic substrates (i.e., phytoplankton cells and, to a greater extent marine aggregates) significantly promote intake of the pathogenic bacterial strain V.

Ostreid herpesvirus‐1 microvariant surveillance in Pacific oysters (Magallana gigas, Thunberg, 1793) in Australia in 2011

Australian Veterinary Journal, Volume 101, Issue 9, Page 345-355, September 2023., 2023
Objective To demonstrate that OsHV‐1 microvariant was limited to the known infected areas in New South Wales at the time of the survey in 2011. Design A 2‐stage survey to demonstrate probability of infection at 2% design prevalence within oyster growing regions and to detect at least one infected region (4% design prevalence) with 95% confidence ...

Site selection for European native oyster (Ostrea edulis) habitat restoration projects: An expert‐derived consensus

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 7, Page 721-736, July 2023., 2023
Abstract The European native oyster (Ostrea edulis) is a threatened keystone species which historically created extensive, physically complex, biogenic habitats throughout European seas. Overfishing and direct habitat destruction, subsequently compounded by pollution, invasive species, disease, predation and climate change have resulted in the ...

Novel RNA viruses in oysters revealed by virome

iMeta, Volume 1, Issue 4, December 2022., 2022
Eighteen novel RNA viruses were found in Crassostrea hongkongensis. Phylogenic analysis shows evidence of recombination between major genes of viruses. Picobirnaviruses are ubiquitous and abundant in oysters.

Chromosomal assembly of the flat oyster (Ostrea edulis L.) genome as a new genetic resource for aquaculture

Evolutionary Applications, Volume 15, Issue 11, Page 1730-1748, November 2022., 2022
Abstract The European flat oyster (Ostrea edulis L.) is a native bivalve of the European coasts. Harvest of this species has declined during the last decades because of the appearance of two parasites that have led to the collapse of the stocks and the loss of the natural oyster beds. O.

Life history of oysters influences Vibrio parahaemolyticus accumulation in Pacific oysters (Crassostrea gigas)

Environmental Microbiology, Volume 24, Issue 9, Page 4401-4410, September 2022., 2022
Summary Vibrio parahaemolyticus infection in humans is associated with raw oyster consumption. Evaluation of V. parahaemolyticus presence in oysters is of most interest because of the economic and public health issues that it represents. To explore V. parahaemolyticus accumulation and depuration in adult Crassostrea gigas, we developed a GFP‐tagged V ...

Ostreid Herpesvirus-1 Infects Specific Hemocytes in Ark Clam, Scapharca broughtonii

Viruses, 2018
High levels of ostreid herpesvirus 1 (OsHV-1) were detected in hemocytes of OsHV-1 infected mollusks. Mollusk hemocytes are comprised of different cell types with morphological and functional heterogeneity.

First characterization of the parasite Haplosporidium costale in France and development of a real‐time PCR assay for its rapid detection in the Pacific oyster, Crassostrea gigas

Transboundary and Emerging Diseases, Volume 69, Issue 5, Page e2041-e2058, September 2022., 2022
Abstract The Pacific cupped oyster Crassostrea gigas is one of the most ‘globalized’ marine invertebrates and its production is predominant in many parts of the world including Europe. However, it is threatened by mortality events associated with pathogenic microorganisms such as the virus OsHV‐1 and the bacteria Vibrio aestuarianus. C. gigas is also a
