Experimental infection of Pacific oyster Crassostrea gigas spat by ostreid herpesvirus 1: demonstration of oyster spat susceptibility
In 2008 and 2009, acute mortalities occurred in France among Pacific cupped oyster, Crassostrea gigas, spat. Different hypothesis including the implication of environmental factors, toxic algae and/or pathogens have been explored. Diagnostic tests indicated that OsHV-1 including a particular genotype, termed OsHV-1 μVar, was detected in most of samples and especially in moribund oysters with th...
متن کاملTechniques for delivery of arachidonic acid to Pacific oyster, Crassostrea gigas, spat: a preliminary investigation
The present study tested two techniques for dietary supplementation of Crassostrea gigas spat with PUFA, such as arachidonic acid (AA). The first technique consisted of a preliminary enrichment and growth of an algal concentrate (T-ISO, Isochrysis sp.) with AA dissolved in an ethanol solution, the whole culture then being fed to the spat. This enrichment increased the AA weight percentage in T-...
متن کاملA Glycoprotein in Shells of Conspecifics Induces Larval Settlement of the Pacific Oyster Crassostrea gigas
Settlement of larvae of Crassostrea gigas on shell chips (SC) prepared from shells of 11 different species of mollusks was investigated. Furthermore, the settlement inducing compound in the shell of C. gigas was extracted and subjected to various treatments to characterize the chemical cue. C. gigas larvae settled on SC of all species tested except on Patinopecten yessoensis and Atrina pinnata....
متن کاملFunctional characterisation of phagocytes in the Pacific oyster Crassostrea gigas
Invertebrates lack canonical adaptive immunity and mainly rely on innate immune system to fight against pathogens. The phagocytes, which could engulf and kill microbial pathogens, are likely to be of great importance and have to undertake significant roles in invertebrate immune defense. In the present study, flow cytometry combined with histological and lectin staining was employed to characte...
متن کاملCerium Inhibits the Cadmium Uptake of Pacific Oyster Crassostrea gigas
Ce is a potential antagonist of Cd due to their similar ionic radius. Its effect on the bioaccumulation of Cd in pacific oyster Crassostreagigaswas explored through laboratory experiments. The oysters were exposed to 5, 10 and 25 μmol/LCe(NO3)3 in the presence of 25 μg/L Cd 2+ (0.22 μmol/L) for 12 days and the concentrations of Cd, Ca, Zn as well as Cu were indicated in the whole soft tissues a...
