Recherches actuelles en pathologie des mollusques

The different epizooties affecting traditional or recent shellfish culture activities (hatcheries, cockle culture) brought to light some microorganisms and parasites considered as the responsible pathogenic agents. However, in a number of cases, the etiology of these massive mortalities remains unexplained (Grassostrea gigas, Ruditapes philippinarum). Some additional works, based on some electron microscopy techniques and isolation methods, are thus essential in order to precise the infectious nature of these diseases.
