| Summary: | The Ostreid herpesvirus 1(OsHV-1) and its microvariants are highly virulent pathogens that cause mass mortalities of oysters and pose a threat to the shellfish aquaculture industry globally. OsHV-1 causes economically devastating mass mortality events up to 100% in the pacific oyster (Crassostrea gigas). However, OsHV-1 and its variants lack host specificity and are known to infect a range of bivalve species, such as bay scallops (Argopecten irradians), and be carried by the European green crab (Carcinus maenas). A recent laboratory study indicates that the eastern oyster (Crassostrea virginica) can experience infection and mortality from OsHV-1 which has significant implications for aquaculture species used in Maryland and globally, as eastern oysters have a wide geographic range spanning Northwest Atlantic to Panama and Venezuela. Therefore, determining the susceptibility of economically and ecologically important United States bivalve species to OsHV-1 is an essential step in improving biosecurity and ... |
