Betanodaviruses cause massive mortality in marine fish species with viral nervous necrosis. The structure of a T = 3 Grouper nervous necrosis virus-like particle (GNNV-LP) is determined by the ab initio method with non-crystallographic symmetry averaging at 3.6 Å resolution. Each capsid protein (CP) shows three major domains: (i) the N-terminal arm, an inter-subunit extension at the inner surfa...
Sea bass nervous necrosis virus is the causative agent of viral nervous necrosis, a disease responsible of high economic losses in larval and juvenile stages of cultured sea bass (Dicentrarchus labrax). To identify genes potentially involved in antiviral immune defense, gene expression profiles in response to nodavirus infection were investigated in sea bass head kidney using the suppression su...
The individual and synergistic antiviral effects of cytokines released by infiltrating immune cells or by cells of the nervous system may play an important role in inhibiting virus spread during infections of the central nervous system (CNS). We examined the antiviral activity against the neurotropic pseudorabies virus (PRV) of interferon-y (IFN-y) and tumour necrosis factor-~ (TNF-ct), and com...
Betanodavirus is a causative agent of viral nervous necrosis syndrome in many important aquaculture marine fish larvae, resulting in high global mortality. The coat protein of Betanodavirus is the sole structural protein, and it can assemble the virion particle by itself. In this study, we used a high-titer neutralizing mAB, RG-M18, to identify the linear B-cell epitope on the viral coat protei...
Barfin flounder nervous necrosis virus (BFNNV), the causative agent of viral nervous necrosis (VNN) of barfin flounder, is vertically transmitted from spawners to larvae. In the present study, an ELISA with a recombinant protein of BFNNV was performed for the detection of antibodies against BFNNV and applied for the selection of brood fish in order to prevent viral vertical transmissions. Brood...
Viral nervous necrosis (VNN), caused by a fish nodavirus, is one of the most serious fish diseases worldwide. Here we report a unique vaccination method in sevenband grouper Epinephelus septemfasciatus using a synthetic double-stranded RNA polyinosinic polycytidylic acid (Poly(I:C)), an interferon inducer, followed by challenge with a live fish nodavirus. Fish injected with Poly(I:C) at 200 mic...
