| 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... |
