Etude des interactions entre l'huître plate Ostrea edulis et le parasite Bonamia ostreae en cytométrie en flux et en hybridation soustractive suppressive (SSH)
Provedor de dados: 5
Autores: Morga, Benjamin.
The French ostreiculture history highlights the fragility of its production caused by stocks overexploitation and diseases. Particularly, the flat oyster production decreased a lot after the appearance of two parasitic diseases: marteilliose and bonamiose. The bonamiose is due to a parasite Bonamia ostreae. The study of interactions between the parasite and oysters hemocytes with flow cytometry allowed to identify modifications of hemocytes activities wh en active parasite is present. On the other hand, inactive parasite does not induce modification for the same hemocyte's activities. Finally, a new study approach, subtractive and suppressive hybridization, has been undertaken in order to identify genes expressed by hemocytes and parasites during in vitro...

Establishing causal link between an infectious agent and mortalities in marine molluscan aquaculture on the example of Bonamia ostreae and Herpèsvirosis in oysters : proposal of a causal grid analysis
Provedor de dados: 5
Autores: Thebault, Anne; Cochennec, Nathalie; Arzul, Isabelle; Renault, Tristan.
In marine molluscan aqauculture, infectious agents are regularly cited in literature associated with mass mortalities as emergin diseases, but the causal link is often based on very few argumeents. 24 ways to demonstrate causal links from epidemiolgical, ecological and marine pathology literature feasible for marine molluscs are given. Those criteria were applied to the ewample of Bonamia ostreae for Ostrea edulis and Herpesvirus for spats and larvae of Crassostrea gigas. Three principles could be applied in marine field for choosing criteria wich should be taken in priority : the demonstration must be given at three levels of organization, organ individual, population, the demonstration must keeps maximum epidemiological criterias, and then mixes...

Bilan des connaissance et des enjeux relatifs aux ressources marines de l'estuaire de l'Odet
Provedor de dados: 5
Autores: Billy, Stéphany; Peronnet, Isabelle.
The estuary of the Odet, which can be defined as a ria, is an integral part of SAGE, taken on by SIVALODET. This space was hardly studied and it seemed important to perform a full assessment of knowledge and issues relating to this ria's fragile and unstable ecosystem. This assessment must be performed according to several points of focus; it must first of all strive to retrace the history of the fisheries in the Odet, then make it possible to identify as clearly as possible the marine habitats that make up this site. With that, it must then bring to light the potential resources of the estuary and finally resituate the Odet in relation to the other Breton estuaries.

L'amélioration des performances de l'huître plate européenne Ostrea edulis par la sélection génétique

The European flat oyster Ostrea edulis has been considered as the traditional French oyster for a very long time and has now nearly disappeared from our farms, as a consequence of the two successive epizootic of the Marteilia refringens parasite and Bonamia ostreae. The actual quasi monoculture of Crassostrea gigas has made necessary the search for a diversification in oyster culture, including the search for a new start of the indigenous flat oyster culture. The Ifremer has been conducting parallel works since 1985 in order to better understand the biology of the parasite as well as to try and select different lines of flat oyster resistant to Bonamia ostreae.
