Physiological changes in Pacific oyster Crassostrea gigas exposed to the herpesvirus OsHV-1 μvar
Since 2008, mass mortality events of Crassostrea gigas have been occurring along the French coast when seawater temperature exceeds 16ºC. These mortality events are related to a particular genotype of the ostreid herpesvirus named OsHV-1 μvar. The present study aimed to detail various physiological...
