Viral Nervous Necrosis due to Betanodavirus: A Case Study in Pot-Bellied Seahorses (Hippocampus abdominals). [PDF]

J Fish Dis
Betanodaviruses, members of the Nodaviridae family, are the causative agents of viral nervous necrosis in fish, resulting in great economic losses worldwide. This is the first case study describing the detection and confirmation of viral nervous necrosis

ICTV Virus Taxonomy Profile: Nodaviridae

Journal of General Virology, 2018
The family Nodaviridae includes two genera, Alphanodavirus and Betanodavirus. The family name derives from the Japanese village of Nodamura where Nodamura virus was first isolated from Culex tritaeniorhynchus mosquitoes.

Genomic characterization of covert mortality nodavirus from farming shrimp: evidence for a new species within the family Nodaviridae.

Virus Research, 2020
The prevalence of covert mortality nodavirus (CMNV) has become one of the major threats to the shrimp farming industry in Asia and South America recently. Here, the genomic RNA1 and RNA2 of CMNV were characterized by using transcriptome sequencing and RT-PCR.

Boolarra virus: a member of the Nodaviridae isolated from Oncopera intricoides (Lepidoptera: Hepialidae).

Intervirology, 1985
A small RNA virus with a bipartite genome was isolated from Oncopera intricoides. It was named Boolarra virus (BoV). The particle had a diameter of 30 nm, a sedimentation coefficient of 140S, and a buoyant density of 1.34 g/ml in CsCl. The capsid proteins were examined by SDS-PAGE and consisted of a major species of molecular weight (mol.

In vitro infection efficiency of nervous necrosis virus alters depending on amount of viral particles adsorbed onto cells

Scientific Reports, 2023
Nervous necrosis virus (NNV) in the family Nodaviridae is one of the simplest spherical RNA viruses and is pathogenic to many fish species. We investigated the effect of purified NNV on striped snakehead cells (SSN-1) in terms of adsorption ratio and ...

Evaluation of the Viral Diversity of Artemia Cysts from Saline Lakes in Kazakhstan Using Viral Metagenomics Analysis

Fishes, 2023
Artemia (brine shrimp) holds significant value as a live feed for larval fish and crustaceans, owing to their distinctive dietary requirements. However, it is vital to acknowledge that Artemia also carries potential risk as a vector of infection.

Sites responsible for infectivity and antigenicity on nervous necrosis virus (NNV) appear to be distinct

Scientific Reports, 2021
Nervous necrosis virus (NNV) is a pathogenic fish-virus belonging to the genus Betanodavirus (Nodaviridae). Surface protrusions on NNV particles play a crucial role in both antigenicity and infectivity.

Novel RNA viruses from the Atlantic Ocean: Ecogenomics, biogeography, and total virioplankton mass contribution from surface to the deep ocean.

Environmental Microbiology, Volume 25, Issue 12, Page 3151-3160, December 2023., 2023
Marine viruses play a major role in the energy and nutrient cycle and affect the evolution of their hosts. Despite their importance, there is still little knowledge about RNA viruses. Here, we have explored the Atlantic Ocean, from surface to deep (4.296

Isolation and characterization of a novel alphanodavirus [PDF]

Virology Journal, 2011
Background Nodaviridae is a family of non-enveloped isometric viruses with bipartite positive-sense RNA genomes. The Nodaviridae family consists of two genera: alpha- and beta-nodavirus. Alphanodaviruses usually infect insect cells.
