Transcriptional responses to Piscine orthoreovirus (PRV) and stress hormones in Atlantic salmon (Salmo salar) red blood cells [PDF]

Fish red blood cells (RBCs) are nucleated and metabolically active with physiological and immunological properties. Salmonid RBCs are target cells of Piscine orthoreovirus (PRV), a double-stranded RNA virus with three known genotypes (PRV-1, 2 and 3 ...

Beating Cardiac Cell Cultures From Different Developmental Stages of Rainbow Trout as a Novel Approach for Replication of Cardiac Fish Viruses. [PDF]

J Fish Dis
ABSTRACT Piscine orthoreovirus‐1 and 3 (PRV‐1, PRV‐3) cause highly prevalent infection in cultured salmonids and can induce heart and skeletal muscle inflammation (HSMI) resulting in economic losses in aquaculture. However, to date, PRV‐1 and PRV‐3 have withstood replication in continuous cell lines.

First description of clinical presentation of piscine orthoreovirus (PRV) infections in salmonid aquaculture in Chile and identification of a second genotype (Genotype II) of PRV. [PDF]

Virol J, 2016
Heart and skeletal muscle inflammation (HSMI) is an emerging disease of marine-farmed Atlantic salmon Salmo salar, first recognized in 1999 in Norway, and recently associated with piscine orthoreovirus (PRV) infection. To date, HSMI lesions with presence of PRV have only been described in marine-farmed Atlantic salmon in Norway. A new HSMI-like disease

Screening of Fish Cell Lines for Piscine Orthoreovirus-1 (PRV-1) Amplification: Identification of the Non-Supportive PRV-1 Invitrome [PDF]

Pathogens, 2020
Piscine reovirus (PRV) is the causative agent of heart and skeletal muscle inflammation (HSMI), which is detrimental to Atlantic Salmon (AS) aquaculture, but so far has not been cultivatable, which impedes studying the disease and developing a vaccine.

Health Surveillance of Wild Brown Trout (Salmo trutta fario) in the Czech Republic Revealed a Coexistence of Proliferative Kidney Disease and Piscine Orthoreovirus-3 Infection

Pathogens, 2020
The population of brown trout (Salmo trutta fario) in continental Europe is on the decline, with infectious diseases confirmed as one of the causative factors.

Melanisation in Salmonid Skeletal Muscle: A Review. [PDF]

J Fish Dis
ABSTRACT Melanisation can occur in the musculature of fish. A well‐known form is the melanised focal changes, or ‘black spots’, in the fillet of farmed Atlantic salmon (Salmo salar). The aetiology of black spots has not been fully determined, though recent research has emphasised the role of fat necrosis in their development.

Piscine orthoreovirus (PRV) ơ3 protein binds dsRNA

Virus Research, 2015
Piscine orthoreovirus (PRV) has a double-stranded, segmented RNA genome and belongs to the family Reoviridae. PRV is associated with heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar L.) and cause intraerythrocytic inclusions.

Heart inflammation and piscine orthoreovirus genotype-1 in Pacific Canada Atlantic salmon net-pen farms: 2016–2019

BMC Veterinary Research, 2022
Piscine orthoreovirus genotype-1 (PRV-1) is a virus commonly associated with Atlantic salmon aquaculture with global variability in prevalence and association with disease.

Classification of Post-Delousing Mortality in Farmed Atlantic Salmon: A Case Study of Standardised Causal Classification at Fish-Level. [PDF]

J Fish Dis
ABSTRACT The study investigated cause‐specific, fish‐level mortality of farmed Atlantic salmon following mechanical delousing. We visited three populations at two marine sites belonging to one company at four different time points, from 1 day before to 13 days after the mechanical delousing. A total of 453 dead fish were collected and necropsied during

Phylogenetic Diversity and Geographic Distribution of Atlantic Salmon Calicivirus in Major Salmon Farming Regions. [PDF]

J Fish Dis
ABSTRACT Salovirus is a genus within the family Caliciviridae, which contains a single member species, Salovirus nordlandense, also known as Atlantic salmon calicivirus (ASCV). While previous work has shown that ASCV can replicate in fish cell lines and establish systemic infection in vivo, its exact role in disease remains unclear and very little is ...
