Epizootiologie des mollusques bivalves : mesures de prophylaxie
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Grizel, Henri.
La conchyliculture résulte de l'évolution d'une activité de cueillette vers une activité sédentaire de culture. Cette évolution s'est faite par étapes dont les principales sont la gestion des gisements naturels, l'affinage des produits issus de ces gisements et la maîtrise du captage et de l'élevage des juvéniles et adultes. Ces différentes étapes sont d'ailleurs encore observables dans plusieurs pays. Cette évolution a été généralement suscitée par l'amélioration du gain et à conduit les éleveurs à accroître le nombre d'animaux élevés sur une superficie déterminée. En contre partie le passage d'une exploitation extensive à une exploitation intensive à fait surgir à plus ou moins long terme des problèmes peu connus jusqu'alors dans les exploitations du...

Etudes pathologiques et epidemiologiques des lesions parasitaires chez Ostrea edulis : Premiers resultats d'un recherche prospective comparative chez les principales especes de mollusques des zones ostreicoles de Bretagne nord

This paper is a contribution to the study of the Bonamia ostreae epizooty in french european oyster Ostrea edulis : parasite process (hemocytic parasitosis); experimental contaminations on parks and in tanks. First results of an epidemiological watch conducted in oyster culture sites show in molluks mytilidae, pectinidae, cardiidae, veneridae: the absence of Bonamia ostreae forms; the existence of different types of parasitism or commensalisus of inequal pathological importance and especially a parasite of the Marteilia genus in Tapes sp . digestive epithelium. Additionally, a new example of hemocytosercoma is observed in Cerastoderma edule .

Modèle d'étude in vitro de Bonamia ostreae (Ascetospora), parasite intrahémocytaire d'Ostrea edulis. Etude d'intéractions cellulaires hôte-parasite
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mourton, Chantal.
Oyster culture is, at a world scale, hit by variious epizooties, which are maintly caused by protozoans of the Phylum Ascetospora. Among them, Bonamia ostreae consitutes an appreciated model in order to study, at the cell scale, host-parasite relationships, as well as the immune role of hemocytes. Indeed, this parasite, which reproduces in hemocytes of Ostrea edulis, but cannot develop in Crassostea gigas. This development of an in vitro model for hemocyte-Bonamia relationships is presented. This includes the development and implementation of various techniques : making primocultures, protocol for infection with purified parasites, histological and immunoenzymatic analyses of infection. Such model allowed to study the interaction between host and...

La mise en évidence d'une infection virale chez l'huître portugaise à l'occasion de l'épizootie de 1970-1974

Among the major epizootics known in marine Molluscs, the one that started on the coasts of Europe in 1970 in the Portuguese oyster, Crassostrea angulata, was certainly one of the largest due to its range and due to the economic loss sustained by the French oyster farming as a whole. It led to the disappearance of the species C. angulata as a farmed oyster, and to the massive introduction of the Japanese oyster, C. gigas, known to be resistant to the disease. From the first manifestations of this epizootic, the laboratories of the ISTPM were actively dedicated to its etiology. Now, after several years, a study begun at the La Tremblade laboratory has just been completed.

Les épizooties en conchyliculture
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Grizel, Henri.
Shellfish culture is widely spread throughout the world and is the focus of an important activity either as a fishing of shellfish deposits or as a culture. The greatest production areas are Northern America with the United States and Canada. Asia with Japan and Korea, Europe with France, the Netherlands and Spain. At some point, each of these countries has had to face more or less important epizooties of variable durations. Each time, some studies have been carried out to try and find the origin of the disease, understand its evolution and look for solutions to the crisis it lead to. If, in most cases, these mortalities could be linked to the presence of some infectious agents, some phenomena still remained unexplained, the mortalities potentially being...
