Complete Genome Sequence of a Fish Nervous Necrosis Virus Isolated from Sea Perch (Lateolabrax japonicus) in China
نویسندگان
چکیده
We sequenced and analyzed the complete genome of a fish nervous necrosis virus isolated from diseased sea perch (Lateolabrax japonicus) in Guangdong Province, China. The virus genome contains RNA1 (3,103 bp) and RNA2 (1,433 bp). Phylogenetic analysis shows that the virus belongs to the redspotted grouper nervous necrosis virus genotype of betanodavirus.

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 کاملNear-Complete Genome Sequence of a Fish Nervous Necrosis Virus Isolated from a Clinical Disease Outbreak in Farm-Reared Bream Sparus aurata in Spain
Sparus aurata larvae infected by viral nervous necrosis were collected from an aquaculture fish farm. The isolated viral genome, composed of two segments (RNA1 and RNA2), was sequenced and analyzed comparatively. Phylogenetic tree analyses revealed that the isolated strain is a reassortant, exhibiting a red-spotted grouper nervous necrosis virus (RGNNV)-type RNA1 and a striped jack nervous necr...
متن کاملComplete Genome Sequence of a Betanodavirus Isolated from Half-Smooth Tongue Sole (Cynoglossus semilaevis)
Betanodavirus, commonly called nervous necrosis virus (NNV) of fish, has emerged as a major constraint on marine aquaculture worldwide. Here, we report the complete genome sequence of a betanodavirus (strain CsCN128) isolated from diseased half-smooth tongue sole (Cynoglossus semilaevis) in China. The genome sequence of strain CsCN128 shares ≥98.7% similarity with seven-band grouper nervous nec...
متن کاملMethylation status and chromatin structure of the myostatin gene promoter region in the sea perch Lateolabrax japonicus (Perciformes).
Myostatin is a negative regulator of the growth and development of skeletal muscle mass. In fish, myostatin is expressed in several organs in addition to skeletal muscle. To understand the mechanisms regulating myostatin gene expression in the sea perch, Lateolabrax japonicus, we examined the methylation status of the myostatin gene promoter region in several tissues (liver, eye, kidney, brain,...

Fish parasites constitute widely diversified groups of unicellular and multicellular organisms. Recently, less known parasite groups have emerged as serious pathogens. Firstly, infection with dinoflagellates of the genus Ichthyodinium has been found during seed production of leopard coral grouper, Plectoropomus leopardus, in Japan and yellowfin tuna, Thunnus albacares, in Indonesia. Schizonts m...
