| Detection of an emerging disease is a crucial aspect for animal health. For the french marine mollusc aquaculture the interest is obvious, after three catastrophic epizooties. The methodological approach must be done by three different disciplines : epidemiology, ecology and marine pathology. Those three approachs are complementary in the special context of marine outbreaks. The uncertainty about many criteria and the lack of proofs feasible for showing the causality link, make the different approachs a necessity. The first step is the study of the three boxes, host, agent, environrnent. This approach, made for studying the cockles of the Croisic's bay could help us to make hypothesis about the possible origins ofmortality, and to a void measurement,... |

| Bacteria of the Vibrio genus are the most predominant infectious agents threatening marine wildlife and aquaculture. Due to the large genetic diversity of these pathogens, the molecular determinants of Vibrio virulence are only poorly understood. Furthermore, studies tend to ignore co-evolutionary interactions between different host populations and their locally encountered Vibrio communities. Here, we explore the molecular targets of such co-evolutionary interactions by analyzing the genomes of nine Vibrio strains from the Splendidus-clade showing opposite virulence patterns towards two populations of Pacific oysters introduced into European Wadden Sea. By contrasting Vibrio phylogeny to their host specific virulence patterns, we could identify two core... |
