Field surveillance has revealed a high prevalence of PRV-3 in clinically healthy salmonids in Italy

Aquaculture Reports
Piscine orthoreovirus genotype 3 (PRV-3) has been reported in several European countries, and in Italy it was detected only once in 2017 without any associated disease outbreak.

Bioinformatics of recent aqua- and orthoreovirus isolates from fish: evolutionary gain or loss of FAST and fiber proteins and taxonomic implications. [PDF]

PLoS ONE, 2013
Family Reoviridae, subfamily Spinareovirinae, includes nine current genera. Two of these genera, Aquareovirus and Orthoreovirus, comprise members that are closely related and consistently share nine homologous proteins.

Pathogen and Gene Expression Profiles of Atlantic Salmon From an Endangered Population

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT The role of pathogens in impacting the behaviour and fate of salmonids has been studied extensively for some selected pathogens such as sea lice. However, the whole pathobiome of the fish are seldom considered and may confound and influence the study species in situ.

The Pathobiome of Salmo trutta From the North Sea to the Barents Sea

Journal of Biogeography, Volume 52, Issue 3, Page 558-570, March 2025.
ABSTRACT Aim Salmonids are some of the best studied species with respect to their pathobiome, and at the northern range limit, there is potential for pathogens to expand with both climate change and increased fish farming in the north. Location We sampled sea‐run brown trout from throughout Norway for gill tissue and conducted both pooled and ...

Additional file 3 of Genetic grouping and geographic distribution of Piscine orthoreovirus-1 (PRV-1) in farmed Atlantic salmon in Norway

, 2021
Additional file 3: Phylogenetic tree constructed from partial sequences of S1 (bp 77–1021) using Maximum Likelihood (ML). The analysis included 37 field isolates (black) and six reference isolates of known virulence (high virulent in red, low virulent in green). Bootstrap values were calculated from 1000 replicates.

Fish Sludge as Feed in Circular Bioproduction: Overview of Biological and Chemical Hazards in Fish Sludge and Their Potential Fate via Ingestion by Invertebrates

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
This review provides knowledge of the biosecurity risks of using fish sludge to produce novel feed ingredients from low‐trophic, extractive animal species in circular value chains. The review includes nutritional composition, sludge treatment practices, EU regulations, and the fate of microbial and chemical hazards contained in sludge till raw ...

Deciphering the pathogenesis of melanized focal changes in the white skeletal muscle of farmed Atlantic salmon (Salmo salar)

Journal of Fish Diseases, Volume 47, Issue 10, October 2024.
Abstract Melanized focal changes (MFCs) in the fillet of farmed Atlantic salmon is a major quality concern. The changes are thought to initially appear as acute red focal changes (RFCs) that progress into chronic MFCs. Recent findings have indicated that hypoxia may be important in their development, possibly leading to necrosis affecting not only ...
