PRV-1 Infected Macrophages in Melanized Focal Changes in White Muscle of Atlantic Salmon (Salmo salar) Correlates With a Pro-Inflammatory Environment

Frontiers in Immunology, 2021
Melanized focal changes in white skeletal muscle of farmed Atlantic salmon, “black spots”, is a quality problem affecting on average 20% of slaughtered fish.

Antiviral Responses and Biological Concequences of Piscine orthoreovirus Infection in Salmonid Erythrocytes

Frontiers in Immunology, 2019
Salmonid red blood cells are the main target cells for Piscine orthoreovirus (PRV). Three genotypes of PRV (PRV-1,2,3) infect Atlantic salmon (Salmo salar), Chinook salmon (Onchorhynchus tshawytscha), Coho salmon (Oncorhynchus kisutch), rainbow trout ...

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.

A novel totivirus and piscine reovirus (PRV) in Atlantic salmon (Salmo salar) with cardiomyopathy syndrome (CMS) [PDF]

, 2010
Background Cardiomyopathy syndrome (CMS) is a severe disease affecting large farmed Atlantic salmon. Mortality often appears without prior clinical signs, typically shortly prior to slaughter.

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 ...

Examination of brown trout decline in the pre-alpine Isar river [PDF]

, 2020
A decline of brown trout (Salmo trutta fario) was observed in the pre-alpine river Isar over the last years. The Bavarian Fisheries Association and local recreational anglers reported high mortalities especially within the warmer summer months.

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 ...

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.
