Effects of dissolved oxygen on survival and immune responses of scallop (Chlamys farreri Jones et Preston)

Physiological and immune responses of zhikong scallop Chlamys farreri to the acute viral necrobiotic virus infection

“…Plasma AKP activity elevated rapidly in AVNV challenged C. farreri at 25 C. Although C. farreri plasma AKP activity has been reported to increase in response to temperature fluctuation, hypoxemia, and Cu 2þ [58,61,62], the plasma AKP activity elevation in viral challenged scallops was not simply induced by a physical stress as the significant differences in plasma AKP activity had been found between the AVNV challenged scallops and the controls. Interestingly, Xing et al [11] did not detect AKP activity in the hemocyte extracts of the AVNV infected C. farreri.…”

Seasonal Variations of Water Temperature, Food Availability, Size, and Reproduction on the Hemocyte Parameters in the ScallopChlamys farreri

“…Low values of THC and GP are considered widely to be a sign of disturbance in the oysters Crassostrea virginica (La Peyre et al 1995) and Saccostrea glomerata (Butt et al 2007), the mussel Mytilus edulis (Pipe & Coles 1995, Parry & Pipe 2004, the clam Mactra veneriformis (Yu et al 2009), and C. farreri (Chen et al 2007a, Xu et al 2008). On the other hand, the activity of intrahemocytic enzymes of bivalves is used increasingly to assess the hostÕs physiological and immunological status (Auffret et al 2006).…”

Transcriptomic response of the Pacific oyster Crassostrea gigas to hypoxia

“…The enzymatic activity of superoxide dismutase (SOD) and catalase in the estuarine fish Leistomus xanthurus was increased during exposure to hypoxia (0.8 mg O 2 L −1 ) for 12 h (Cooper et al, 2002). SOD enzymatic activity was also increased in the scallop Chlamys farreri at 4.5 and 2.5 mg O 2 L −1 after 12 h (Chen et al, 2007). Finally, a previous study on the transcriptomic response to hypoxia using SSH on C. gigas under the same hypoxic conditions indicated that some genes of the oxidative metabolism (glutathione peroxidase and glutathione transferase) were up-regulated after 7-10 d of exposure to hypoxia (David et al, 2005).…”
