Taxonomie et virulence de vibrions pathogènes d'huîtres creuses Crassostrea gigas
Provedor de dados: 5
Autores: Le Roux, Frédérique.
As the emergence of new vibriosis in the European Atlantic coasts has been associated with mass mortalities of molluscs cuasing important economic losses, the project obectives are to provide knowledge and operational tools to evaluate the impact of vibriosis on farmed japenese oyster Crassostrea gigas. Facing the diversity of Vibrio species associated to bivalve disease outbreaks, the difficulties of identification and the detemrination of their pathogenic abilities we propose a double approach to correlate phenotype/geneotype of a bacteria with risk of disease : 1) by genotyping we will evaluate if specific strains are associated with disease. 2) by evaluating likely virulence mechanisms implicated in pathogenesis, we will characterise the genes...

Développement de marqueurs moléculaires liés à la résistance à la mortalité estivale chez l'huître creuse Crassostrea gigas - Approche QTL
Provedor de dados: 5
Autores: Sauvage, Christopher.
The Pacific oyster Crassostrea gigas is the most cultivated marine species in the world (4.2 million tonnes for a turnover of 3.5 billion US dollars according to the FAO 2005). Flat oyster culture is one of the components of the French economic activity. However, for more than 15 years, farms have had to face some summer mortality episodes (30 %-60 %), that could jeopardize European mollusc culture competitivity. More than the economical importance of C. gigas, which justifies a great research effort, oysters constitute a study model of the complex physiological and genetic basis (i.e. growth, reproduction, and survival) strongly correlated to the oyster's response to different environmental conditions. One of the considered solutions is the selection of...
