Cytometric investigations on hemocytes of the American oyster, Crassostrea virginica
Tissue and Cell, 1988Pericardial hemolymph was obtained from American Oysters (Crassostrea virginica) and the hemocytes characterized by flow cytometry. The cells were found to have a broad unimodal size distribution with a median diameter of 7 micrometers. Total protein measured by flow cytometric fluorescence of dansylated cells also revealed a broad unimodal ...

Kinetic properties of lysozyme from the hemolymph of Crassostrea virginica
Journal of Invertebrate Pathology, 1974Abstract Lysozyme activity has been demonstrated in both the supernatant and pellet fractions of whole hemolymph of the American oyster, Crassostrea virginica , subjected to centrifugation at 4000 and 10,000 × g . In each case the enzyme activity is greater in the supernatant than in the pellet.

Crassostrea virginica as an indicator of cadmium pollution
Marine Biology, 1980As much as 89, 176 and 292 μg Cd g-1 dry weight were accumulated by adult Crassostrea virginica after treatment for 40 wk with 5, 10 and 15 μg Cd kg-1, respectively, in flowing seawater at ambient salinity and temperature without mortalities. Cadmium accumulation increased with increased concentration of cadmium in seawater; greater amounts were ...

The bioconcentration and metabolism of chlorpyrifos by the eastern oyster,Crassostrea virginica
Environmental Toxicology and Chemistry, 2003AbstractEastern oysters (Crassostrea virginica) were exposed to [14C]chlorpyrifos (O,O-diethyl-O-[3,5,6-trichloro-2-pyridyl] phosphorothioate) at an average measured seawater concentration of 0.6 μg/L under flow-through conditions for 28 d. The compound O,O-diethyl-O-(3,5-dichloro-6-methylthio-2-pyridyl)phosphorothioate (DMP) was extracted and ...

Fertilization Interference Between Crassostrea ariakensis and Crassostrea virginica: A Gamete Sink
Journal of Shellfish Research, 2008Published data indicate that spawning seasons for the Asian oyster Crassostrea ariakensis and the eastern oyster C. virginica overlap. Hybrids can form, but the larvae are not viable. If C. ariakensis is introduced into Chesapeake Bay and synchronous spawning occurs with native C.

Lysozymelike Activities in the Hemolymph of Crassostrea virginica
1974In recent years the presence of lysozymelike activities in the hemolymph of invertebrates has been documented with increasing frequency. Mohrig and Messner (1968) report the occurrence of lysozyme at a level of 25–500 µg/ml in the hemolymph of normal Gallaria mellonella. This level can, however, be elevated nonspecifically up to a maximum of 9000 µg/ml

Quantitative studies on trehalose in the oyster, Crassostrea virginica Gmelin
Comparative Biochemistry and Physiology, 1967Abstract 1. 1. Trehalose was identified in the oyster, Crassostrea virginica Gmelin, and found to be present throughout the period of one year in amounts ranging from 0·188 mg/g wet wt. to 3·300 mg/g wet wt. 2. 2. Trehalose levels remained constant except for February and July, when they were significantly elevated. 3. 3.
