Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

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

Scientific 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 ...

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

Transboundary 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

Insect 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.

Viral delivery of dsRNA for control of insect agricultural pests and vectors of human disease : prospects and challenges [PDF]

, 2017
RNAi is applied as a new and safe method for pest control in agriculture but efficiency and specificity of delivery of dsRNA trigger remains a critical issue. Various agents have been proposed to augment dsRNA delivery, such as engineered micro-organisms
