The mechanism that bivalve molluscs react to infectious agents are important research subjects in the fIeld of disease control studies for these animals. While the selection of disease resistant populations have made decisive progression in some species, the mechanism behinds these resistant phenomena is not yet clear so far. However, hemocytes must represent one of the key factors in the reaction process. Based on this hypothesis, the structure and function of European flat oyster, Ostrea edulis, hemocytes have been investigated in aid of different techniques in the present study. ln addition, Pacific oyster, Crassostrea gigas, hemocytes have been analysed in certain aspects so as to provide some results for comparison. European flat oyster and Pacific... |
