Experimental herpes-like viral infections in marine bivalves: demonstration of interspecies transmission
Since 1972, herpes-like virus infections have been reported in several marine bivalve species around the world. Viral detection was often associated with high mortality rates in larvae and spat. To determine whether a single virus is able to infect different bivalve host species, we carried out expe...
