Myosin light chain 3 serves as a receptor for nervous necrosis virus entry into host cells via the macropinocytosis pathway [PDF]

eLife
Nodaviridae infections cause severe mortality in insects and fish, with nervous necrosis virus (NNV) posing significant threats to global fish populations. However, the host factors involved in NNV entry remain poorly understood. We identify myosin light

The infectivity of virus particles from Wolbachia-infected Drosophila [PDF]

BMC Microbiology
Viruses transmitted by arthropods pose a huge risk to human health. Wolbachia is an endosymbiotic bacterium that infects various arthropods and can block the viral replication cycle of several medically important viruses.

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

J Fish Dis
ABSTRACT 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 in pot‐bellied seahorses (Hippocampus abdominalis) in Australia.

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.

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
In this study weexplored the Atlantic Ocean from 3 to 4,296 m to enhance our understanding of RNA viruses. Data revealed that overall RNA viruses potentially accounted for 5.2‐24.4% of the virioplankton with ≈106 VLP/ml. We identified 2,481 putative viral contigs, including 88 new RNA viruses highly endemic with no apparent association with depthor ...

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.

The Viromes of Mosquitoes from the Natural Landscapes of Western Siberia

Viruses, 2023
The metagenomic analysis of mosquitoes allows for the genetic characterization of mosquito-associated viruses in different regions of the world. This study applied a metagenomic approach to identify novel viral sequences in seven species of mosquitoes ...

Viral nervous necrosis (VNN) an emerging disease caused by Nodaviridae in aquatic hosts: Diagnosis, control and prevention: A review

, 2019
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 ...
