Betanodaviruses are small ssRNA viruses responsible of Viral Nervous Necrosis in marine fishes worldwide. In this study, we examined bivalve mollusks for the presence of Betanodavirus and genetically analyzed the detected viruses to find out whether these animals could be a source of genetically closely related Betanodaviruses transmissible horizontally to wild and farmed fish. No viruses were detected in mussels (M. galloprovincialis), whereas clams (T. philippinarum) and oysters (C. gigas), both species reared on the seabed, resulted highly positive (26.6%). Phylogenetic analysis showed the belonging of these viruses to the RGNNV genotype. This is the first study focusing on Betanodavirus in bivalve mollusks; it evidences important presence of Betanodaviruses in bivalve mollusks; in some cases viral strains are highly correlated to those found in fish. These results highlight the possible role of mollusks in the spread of Betanodavirus to wild and farmed fish.

Abstract

Betanodaviruses are small ssRNA viruses responsible of Viral Nervous Necrosis in marine fishes worldwide. In this study, we examined bivalve mollusks for the presence of Betanodavirus and genetically analyzed the detected viruses to find out whether these animals could be a source of genetically closely related Betanodaviruses transmissible horizontally to wild and farmed fish. No viruses were detected in mussels (M. galloprovincialis), whereas clams (T. philippinarum) and oysters (C. gigas), both species reared on the seabed, resulted highly positive (26.6%). Phylogenetic analysis showed the belonging of these viruses to the RGNNV genotype. This is the first study focusing on Betanodavirus in bivalve mollusks; it evidences important presence of Betanodaviruses in bivalve mollusks; in some cases viral strains are highly correlated to those found in fish. These results highlight the possible role of mollusks in the spread of Betanodavirus to wild and farmed fish.
