Mass Mortality of Cultured Sevenband Grouper, Epinephelus septemfasciatus, Associated with Viral Nervous Necrosis
Mass mortalities of sevenband grouper Epinephelus septemfasciatus reared in Oita Prefecture were investigated. The outbreaks of the disease occurred in summer seasons (July to October; water temperature 25-28°C) of 1993 and 1994. Affected fish ranging 170 to l,85Og in body weight were characterized by upside down swimming and inflation of swimbladder. Histopathologically, necrosis and vacuolati...
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 کاملComplete Genome Sequence of Nervous Necrosis Virus Isolated from Sevenband Grouper (Epinephelus septemfasciatus) in South Korea
The draft genome sequence of the nervous necrosis virus (NNV) SGYeosu08, isolated from sevenband grouper (Epinephelus septemfasciatus) in Yeosu, South Korea, was cloned and analyzed. The full-length RNA1 was a 3,103-nucleotide-encoding region of RNA-dependent RNA polymerase, and the RNA2 encoding a coat protein was 1,433 nucleotides in length. This genome sequence might be useful in the develop...
متن کاملComplete Genome Sequence of Nervous Necrosis Virus Isolated from Orange-Spotted Grouper (Epinephelus coioides) in Taiwan
The genome sequence of nervous necrosis virus strain KS1 isolated from orange-spotted grouper (Epinephelus coioides) was cloned and analyzed. The viral genome is composed of two single-stranded positive-sense RNA molecules, RNA1 and RNA2. Phylogenetic analysis shows that the virus strain KS1 belongs to the red-spotted grouper nervous necrosis virus genotype.
متن کاملViral nervous necrosis (VNN) an emerging disease caused by Nodaviridae in aquatic hosts: Diagnosis, control and prevention: A review
Betanodavirus is one of the two genera making up the family Nodaviridae and is the etiological agent of viral nervous necrosis (VNN, also known as viral encephalopathy and retinopathy or VER). The virus infects a large range of host species in more than 50 species of marine and freshwater fish worldwide from different geographical areas and the known host range continues to expand as new specie...
