Última Parasites nouveaux de la glande digestive des mollusques marins Mytilus edulis L. et Cardium edule L. ArchiMer Comps, Michel; Grizel, Henri; Tige, Gilbert; Duthoit, Jean-louis. Some similar stages to those of the digestive gland parasite in the Ostrea edulis have been observed in the Mytilus edulis as well as in the Cardium edule in which the simultaneous presence of some Microsporidia spores was noticed. Their study with an electron microscope enabled the description of their structural specificities and characteristics.

Numerous diseases have been described in Ostrea and Crassostrea oysters and especially in cultivated species of commercial interest. The lack of growth, but more often mortalities, are in most cases the most obvious symptoms of this supposed sickness. The consequences of these epizooties can be so bad that they can result in the disappearance of an entire oyster population from a determined area as for Ostrea edulis L. in 1920-1921 (Dollfus, 1922) on some coasts of Europe and for Crassostrea angulata LMK in 1970-1971 on the French Atlantic coast and especially in the Marennes-Oléron and Arcachon basins. These cases can be considered as extreme cases as most of the time, oysters are only subjected to a number of episodic affections, affecting the farms only...

Ano: 1974 URL: http://archimer.ifremer.fr/doc/1974/publication-6286.PDF Infections virales chez les huîtres Crassostrea angulata Lmk. et Crassostrea gigas Th. ArchiMer Comps, Michel; Duthoit, Jean-louis. Two viral infections associated to some epizooties have been observed in Crassostrea angulata Lmk. The first one concerns the Gill disease in which the viral damages go hand in hand with a cellular hypertrophy, while, in the second one, the contaminated cells are associated with a deterioration of the connective tissue. These branchial necrosis associated to a virus have been observed again recently in some Portuguese oysters from the natural deposits of the Cadix (Spain) area. Moreover, the study of the summer mortalities (July 1977) in the oyster Crassostrea gigas Th. demonstrated the presence in this species of a virus of the same type as the one associated to the massive mortalities of the Portuguese oyster. In both cases, the viral morphogenesis takes...

Ano: 1979 URL: http://archimer.ifremer.fr/doc/1979/publication-5922.PDF Infection virale associée à la "maladie des branchies" de l'huître portugaise Crassostrea angulata LmK ArchiMer Comps, Michel; Duthoit, Jean-louis. Some particles and viral damages linked to a strong cellular hypertrophy have been observed in the branchial necrosis of some Portuguese oysters contaminated by the Gill disease. The structure and development of the virions, as well as the cellular alteration, are studied by electron microscopy. Tipo: Text Palavras-chave: Crassostrea angulata; Huître; Pathologie; Virologie. Ano: 1976 URL: http://archimer.ifremer.fr/doc/1976/publication-5920.PDF Micro-organismes de type Rickettsien chez les huîtres Crassostrea gigas Th. et Ostrea edulis L. ArchiMer Comps, Michel; Tige, Gilbert; Duthoit, Jean-louis; Grizel, Henri. Some rickettsian infections have been found in French Atlantic oysters, Crassostrea gigas and Ostrea edulis. The micro-organisms parasite the digestive diverticulum epithelium cells although not creating any damage that could strongly affect the molluscs. If not for its shape, which appears to be longer in the case of the Crassostrea gigas Rickettsia, the characteristics of these two micro-organisms seem pretty close and enabled their inclusion in the Rickettsial order.
