Altered conformational structures of nervous necrosis virus surface protrusions and free coat proteins after incubation at moderate-low temperatures

open access: yesScientific Reports, 2019
Nervous necrosis virus (NNV) is a pathogenic fish virus belonging to family Nodaviridae. The objective of this study was to analyze stabilities of NNV surface protrusion and free coat protein (CP) conformational structures by analyzing changes of NNV ...

Susceptibilities of medaka (Oryzias latipes) cell lines to a betanodavirus

open access: yesVirology Journal, 2010
Background Betanodaviruses, members of the family Nodaviridae, have bipartite, positive-sense RNA genomes and are the causal agents of viral nervous necrosis in many marine fish species.

Gut Virome of Tibetan Pigs Reveals the Diversity, Composition, and Distribution of Potential Novel Viruses/Variants

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
As a local breed adapted to the extreme environment of the Tibetan Plateau, Tibetan pigs have not yet been systematically characterized in terms of their gut viral communities. In this study, we applied viral metagenomics to sequence fecal samples from 191 Tibetan pigs (including both healthy and diarrheal individuals) across four farms in Nyingchi ...

The RNA interference response to alphanodavirus replication in Phlebotomus papatasi sand fly cells

open access: yesInsect Molecular Biology, Volume 33, Issue 6, Page 687-696, December 2024.
Both the siRNA and piRNA pathways are transcriptionally active in Phlebotomus papatasi PP9ad cells. Assembly of small RNA sequencing identifies an adventitious nodavirus (American nodavirus [ANV]) in PP9ad cells. ANV is actively replicating in PP9ad cells and is targeted by the exo‐siRNA pathway but not the piRNA pathway.
