Haplosporidiosis of the Pacific oyster, Crassostrea gigas

Journal of Invertebrate Pathology, 1991
Haplosporidan parasites were observed in 10/100 spat and 1/171 adult Pacific oysters, Crassostrea gigas, reared in Matsushima Bay, Japan. Eight of the infected spat contained mild to severe plasmodial infections. The multinucleated plasmodia were 6-12 microm x 7-15 microm and were associated with an infiltration of hemocytes that occurred throughout ...

NUCLEOTIDES OF THE PACIFIC OYSTER CRASSOSTREA GIGAS (THUNBERG)

Canadian Journal of Biochemistry, 1964
The nucleotides of the Pacific oyster Crassostrea gigas (Thunberg) have been fractionated by chromatography on diethylaminoethyl cellulose and characterized by their ultraviolet absorption and paper chromatographic properties. Major components were adenosine-5′ phosphate, adenosine-5′ diphosphate, and adenosine-5′ triphosphate.

Bindin genes of the Pacific oyster Crassostrea gigas

Gene, 2008
When Crassostrea gigas oyster sperm acrosome react a ring of bindin protein is exposed that bonds the sperm to the egg vitelline envelope. The putative functional unit of bindin is a fucose lectin (F-lectin) domain that is structurally conserved among phyla. There is only one bindin gene in C.

Xenobiotic biotransformation in the pacific oyster (Crassostrea gigas)

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989
1. Oyster visceral mass and gill tissues possessed measurable flavin-containing monooxygenase (FMO) activity. 2. FMO activity was confirmed in visceral mass microsomes by oxygen uptake experiments utilizing various nitrogen and sulfur-containing chemicals along with measurement of N,N-dimethylaniline (DMA) N-oxidase and methimazole oxidation activities.

Successful cryopreservation of Pacific oyster (Crassostrea gigas) oocytes

Cryobiology, 2005
Protocols for cryopreservation of sperm and oocytes would provide the ultimate control over parental crosses in selective breeding programmes. Sperm freezing is routine for many species, but oocyte freezing remains problematic, with virtually zero success in aquatic species to date.

Uptake of cadmium from Pacific oysters (Crassostrea gigas) in British Columbia oyster growers

Environmental Research, 2008
Pacific oysters along the North American coast from Washington to Alaska contain concentrations of cadmium (Cd) that are high by comparison with Atlantic oysters, frequently exceeding 2mug/g wet weight, but it is unclear whether this Cd is absorbed by consumers.To determine the effect of oyster consumption on Cd in blood and urine among a group with ...

Galactosylation of Glycoconjugates Using Pacific Oyster Β-1,3-Galactosyltransferases

Carbohydrate Research
The Pacific oyster (Magallana gigas) exhibits an extensive diversity of N- and O-linked glycoconjugates, offering significant potential for biotechnological applications. Through genomic data mining, we have identified and characterized a suite of β-1,3-galactosyltransferase enzymes, pivotal for the synthesis of glycan structures.

Particle Processing by Olympia Oysters Ostrea lurida and Pacific Oysters Crassostrea gigas

Estuaries and Coasts, 2019
The native Olympia oyster (Ostrea lurida) has been the subject of few detailed feeding studies compared with many other species of bivalve mollusk. More information on this species’ feeding activity and behavior are needed to better understand its historical ecological role in Pacific Northwest (PNW) estuaries, compared with that of the widely farmed ...
