Bachere, Evelyne / Chagot, Dominique / Grizel, Henri - 1988There is an ongoing need to isolate and purify ceIls in bivalve mollusc disease research. Many separation techniques differentiate cells solely by a single factor and usually require additives in the medium that may damage live cells. Centrifugai elutriation is a technique that separates particles...Contributeur (s):

Bachere, Evelyne / Chagot, Dominique / Tige, Gilbert / Grizel, Henri - 1986Considering the epizootics which affect the French stock of flat oysters, Ostrea edulis (Grizel, 1985), trials to introduce an Australian oyster, Ostrea angasi, have been undertaken. The spat produced in a hatchery from breeders imported from Australia were reared in the south ofBrittany and in...Contributeur (s):

Comps, M / Chagot, Dominique - 1987Perkinsus-like parasite has been observed within the tissues of the Clam Ruditapes decussatus from Portugal. The structure of the vegetative stages is described.Contributeur (s):

Legall, Ghyslaine / Chagot, Dominique / Mialhe, Eric / Grizel, Henri - 1988A branchial infection of Pecten maximus is histologically and ultrastructurally described. Gill epithelial cells were heavily infected with colonies of procaryotes, believed ta belong to the Rickettsiales.Contributeur (s):

Mialhe, Eric / Chagot, Dominique / Boulo, Viviane / Comps, Michel / Ruano, Francisco / Grizel, Henri - 1987The authors report the presence of a Rickettsia in Ruditapes decussatus from natural populations of the Algarve (Portugal). Light microscopic shows infections of varying importance in gill tissues. Some enclose small procaryotic colonies (cp) scattered in all lamellae; in others, the colonies are...Contributeur (s):

Noel, Danielle / Boulo, Viviane / Chagot, Dominique / Mialhe, Eric / Paolucci, Francis / Clavies, Christine / Hervaud, Eric / Elston, Ralph - 1991Mytilus edulis develop progressive and fatal hemocytic neoplasia. We have generated monoclonal antibodies using neoplastic hemocytes from highly infected individuals collected from Puget Sound in Washington State (USA). Twenty-seven monoclonal antibodies against neoplatic cell antigens were...Contributeur (s):

Hervio, Dominique / Chagot, Dominique / Godin, Pierre / Grizel, Henri / Mialhe, Eric - 1991Acid phosphatase activity was cytochemically detected at the ultrastructural level in the protozoan Bonamia ostreae, an intrahemocytic parasite of the flat oyster Ostrea edulis. Lead nitrate was used as capture agent for phosphate liberated during the hydrolysis of the subtrate (cytidine 5'...Contributeur (s):

Chagot, Dominique / Alzieu, Claude / Sanjuan, Jane / Grizel, Henri - 1990Shell malformations and histological effects of environmental concentrations of TBTF (2, 13.1 and 64.8 ng/!) were assessed on adult oysters Crassostrea gigas during a I-month experiment, incIuding both an exposure and a depuration phase. The results showed that the digestive gland is the primary...Contributeur (s):

The edge and isthmus of the mantle of Pinctada margaritifera (Mollusc, Bivalvia) were studied using light and electron microscopy from a morphological and histochemical point of view. Six areas with several subareas were differentiated in the mantle edge. One of these areas is similar to the...Contributeur (s):

Latrouite, Daniel / Morizur, Yvon / Noel, Philippe / Chagot, Dominique / Wilhelm, G - 1988Unusural crab mortality in winter led us to identify a Hematodinium like parasitic dinoflagellate in the blood of edible crabs Cancer pagurus. Crabs from several fishing areas (the English Channel, the Iroise sea, the bay of Biscay, off Scotland) and from one area of the Channel shore were examined...Contributeur (s):
