Infectious diseases are mostly explored using reductionist approaches despite repeated evidence showing them to be strongly influenced by numerous interacting host and environmental factors. Many with a complex aetiology therefore remain misunderstood. By developing holistic approach tackle the complexity of interactions, we decipher intra-host interactions underlying Pacific oyster mortality syndrome affecting juveniles Crassostrea gigas, main species exploited worldwide. Using experimental...
Upon incubation at 37 degrees C in the absence of Ca2+ ions, pathogenic yersiniae release large amounts pYV plasmid-encoded proteins called Yops that are involved pathogenesis. Yersinia enterocolitica also expresses an outer membrane protein is considered adhesin and YadA (previously P1 or YopA). The production coordinately regulated by a 20-kb region plasmid referred to as dependence containing least four loci virA, virB, virC, virF. virF gene encodes key transcriptional activator yop...

Abstract Background Although bivalves are among the most-studied marine organisms because of their ecological role and economic importance, very little information is available on genome sequences oyster species. This report documents three large-scale cDNA sequencing projects for Pacific Crassostrea gigas initiated to provide a large number expressed sequence tags that were subsequently compiled in publicly accessible database. resource allowed identification transcripts provides valuable...

In France, two main diseases threaten Pacific oyster production. Since 2008, Crassostrea gigas spat have suffered massive losses due to the ostreid herpesvirus OsHV-1, and since 2012, significant mortalities in commercial-size adults been related infection by bacterium Vibrio aestuarianus. The genetic basis for resistance V. aestuarianus OsHV-1 nature of correlation between these traits were investigated using 20 half-sib sire families, each containing full-sib families. For disease,...
Selective breeding has been successfully applied to improve profitability and sustainability in numerous aquatic species. Recent developments of high throughput genotyping technology now enable the implementation genomic selection, a method aiming predict value candidates based on their genotype at genome-wide markers. In this review article, we state arts, challenges prospects for application selection aquaculture The particular focus is status several major species International Council...
We investigated the quantitative genetics of plasticity in resource allocation between survival, growth and reproductive effort Crassostrea gigas when food abundance varies spatially. Resource shifted from survival to as increased. An optimality model suggests that this plastic shift may be adaptive. Reproductive mean were highly heritable, whereas for growth, both had low heritability. The genetic correlations negative poor treatments, suggesting trade-offs, but positive rich ones. These...
Summer mortality is a phenomenon severely affecting the aquaculture production of Pacific oyster (Crassostrea gigas). Although its causal factors are complex, resistance to has been described as highly heritable trait, and several pathogens including virus Ostreid Herpes type 1 (OsHV-1) have associated with this phenomenon. A QTL analysis for survival summer OsHV-1 load, estimated using real-time PCR, was performed five F(2) full-sib families resulting from divergent selection experiment...
Background Bacterial infections are common in bivalve larvae and can lead to significant mortality, notably hatcheries. Numerous studies have identified the pathogenic bacteria involved such mortalities, but physiological changes associated with pathogen exposure at larval stage still poorly understood. In present study, we used an integrative approach including physiological, enzymatic, biochemical, molecular analyses investigate energy metabolism, lipid remodelling, cellular stress, immune...
