| Among the marine molluscs, Pacific oyster, Crassostrea gigas, is actually the most reared species in the world. Noticeably in France, where it was imported between 1960 and 1970, and replaced Portuguese oyster, Crassostrea angulata. Intensification of breeding and the associated introductions of new species may be hazardous. Indeed, they might be responsible for the appearance and the dissemination of new diseases in bivalve molluscs. In addition to these observations, the quasi monobreeding of C. gigas in France enhances the necessity to develop research concerning the diagnosis of pathologies affecting this species, namely the diagnosis of viral diseases. Several families of viruses have been described within marine bivalves molluscs. The purpose of this... |

| Trois types d'infections intracellulaires des molluques bivalves marins sont étudiés dans leurs aspects histologiques et ultrastructuraux. La première partie traite de deux maladies causées par des virus ADN intracytoplasmiques chez les huîtres Crassostrea angulata et Crassostrea gigas : la maladie des branchies et les mortalités massives de 1970 à 1977. Les caractéristiques morphologiques et ultrastructurales de vrions, leur morphogénèse et les effets pathogènes sont décrits et développés dans une étude comparative des deux types de viroses. Dans la seconde partie sont abordées les infections rickettsiennes des Pélécypodes marins avec la description de procaryotes appartenant aux Rickettsiales et d'agents infectieux à cycle de développement... |

| Among the Iridovirus related infections frequently described on many teleosts fish species, Viral Erythrocytic Necrosis (VEN) (Pinto et al., 1989), Epizootic Haematopoietic Necrosis Virus (EHNV) (Langdon et al., 1988) as weil as Lymphocystis Disease Virus (LDV) are not considered to directly cause fatality. Indeed, Lymphocystis outbreaks of farmed fish could be observed in some cases, as a consequence of a bacterial double infection or cannibalism (Ahne ef al., 1991; Moate et al., 1992). Here, we report for the first time a strong LDV infection, and an additional physical stress responsible for mortalities of reared sea bream, Sparus aurata, from Toulon area, on French Mediterranean coast. Although, since the first report of Lymphocystis in sea bream under... |

| Among the marine molluscs, Pacifie oyster, Crassostrea gigas, is actually the most reared specie in the world. Noticely in France, where it was imported between 1960 and 1970, and replaced by Portuguese oyster, Crassostrea angulata, which specie was decimated during this period because of iridoviruses. Uncontroled introductions of new species may however be hazardous. Indeed, they might be responsible for the appearance and the dissemination of new diseases of bivalve molluscs in importing country. In addition to these observations, the quasi monobreeding of Pacific oyster in France enhances the necessity to develop research concerning the diagnosis of pathologies affecting this specie, namely the diagnosis of viral diseases.
