Characterization of grouper nervous necrosis virus (GNNV)
Grouper nervous necrosis virus (GNNV) was isolated from moribund grouper larvae, Epinephelus sp., using a ®sh cell line GF-1. The present study describes the biochemical and biophysical properties of GNNV and the expression of GNNV in diseased grouper larvae. Viral protein was detectable in most of the GNNV-infected GF-1 cells by the ̄uorescent antibody technique (FAT) after 12 h post-infection...
متن کاملPathogenicity of viral nervous necrosis virus for Guppy fish, Poecilia reticulata
The pathogenicity of a Nervous Necrosis Virus isolate obtained from naturally infected Golden grey mullet (Liza auratus) suffering serious mortalities in Iranian coastline water of the Caspian Sea was investigated for first time. An experimental infection has been performed using three groups, two experimental groups and one control group of Guppy (Poecilia reticulata) with mean weight 0.47±0.0...

متن کاملAn overview of Betanodavirus and perspective of Viral Nervous Necrosis (VNN) disease in Iranian southern waters
The Persian Gulf and its shores are important and strategic areas with a large variety of fish species. Betanodavirus infection is known to be a serious threat to susceptible fish and causing economic damages to the fisheries and fishing industry. Concerning to isolation and confirmation of VNN virus in the Mullet fish (Chelon aurata and C. saliens) in the Caspian Sea and its damages on Mullet ...
متن کاملIdentification of host-specificity determinants in betanodaviruses by using reassortants between striped jack nervous necrosis virus and sevenband grouper nervous necrosis virus.
Betanodaviruses, the causal agents of viral nervous necrosis in marine fish, have bipartite positive-sense RNAs as genomes. The larger genomic segment, RNA1 (3.1 kb), encodes an RNA-dependent RNA polymerase, and the smaller genomic segment, RNA2 (1.4 kb), codes for the coat protein. Betanodaviruses have marked host specificity, although the primary structures of the viral RNAs and encoded prote...
