The goal of the present study was to elucidate the modulatory effects of cadmium (Cd) on hypoxia/reoxygenation-induced mitochondrial dysfunction in light of the limited understanding of the mechanisms of multiple stressor interactions in aquatic organisms. Rainbow trout (Oncorhynchus mykiss) liver m...

We investigated how temperature modulates cadmium (Cd)-induced mitochondrial bioenergetic disturbances, metal accumulation and volume changes in rainbow trout (Oncorhynchus mykiss). In the first set of experiments, rainbow trout liver mitochondrial function and Cd content were measured in the presen...

Thermal stress may influence how organisms respond to concurrent or subsequent chemical, physical and biotic stressors. To unveil the potential mechanisms via which thermal stress modulates metals-induced bioenergetic disturbances, the interacting effects of temperature and copper (Cu) were investig...

Background: Piscine reovirus (PRV) is a newly discovered fish reovirus of anadromous and marine fish ubiquitous among fish in Norwegian salmon farms, and likely the causative agent of heart and skeletal muscle inflammation (HSMI). HSMI is an increasingly economically significant disease in Atlantic ...

Abstact: Infectious salmon anaemia (ISA) is a serious disease of marine-farmed Atlantic salmon (Salmo salar) caused by ISA virus (ISAV), which belongs to the genus Isavirus, family Orthomyxoviridae. ISA is caused by virulent ISAV strains with deletions in a highly polymorphic region (HPR) of the hem...

Mast cells are crucial effector cells in host defense and immunoregulation. They are equipped with an impressive array of receptor systems which allows them to rapidly respond to pathogen-associated signals. G protein-coupled receptors (GPCRs) mediate mast cell activation and mediator release in res...

Farmed fish provide an increasing fraction of the human food supply, and are of major economic importance in many countries. As in the case of terrestrial agriculture, bringing together large numbers of animals of a single species (i.e., monoculture) increases the risk of infectious disease outbreak...

Reverse transcription-real time polymerase chain reaction (real time RT-PCR) assay with Universal Probe Library (UPL) probes has been developed for the detection and genotyping of Chilean infectious pancreatic necrosis virus (IPNV) isolates from infected cell culture. Partial nucleotide sequences (1...

Although the Mallard (Anas platyrhynchos) is considered an important maintenance host for low pathogenic avian influenza (LPAI) viruses, viral cell tropism and pathology in naturally infected birds are largely unknown. In August 2006, we collected 19 free-living hatch-year Mallards that were positiv...

Fourteen laboratories validated their procedure for detection of infectious salmon anaemia virus (ISAV) in fish tissues using TaqMan® real-time RT-PCR targeting ISAV RNA segment 8. The participants included 12 laboratories from South America, one from Asia and one from Europe. The OIE Reference Lab...

Surveillance for avian influenza viruses in wild birds was initiated in Canada in 2005. In 2006, in order to maximize detection of highly pathogenic avian influenza viruses, the sampling protocol used in Canada's Inter-agency Wild Bird Influenza Survey was changed. Instead of collecting a singl...

Finfish nodaviruses (betanodaviruses) can cause highly destructive infections in numerous species of farmed marine fish larvae and juveniles worldwide. The betanodavirus genome consists of two single-stranded positive-sense RNA molecules (RNA1 and RNA2). The virus can be classified into four genotyp...

The application of genetic modification offers considerable opportunities for more efficient and more effective fish aquaculture. Susceptibility to infectious diseases and limitations in growth rates could be successfully tackled by the application of transgenic technology. Acceptance of transgenic ...

Teleost fish represent a transition point on the phylogenetic spectrum between invertebrates that depend only on innate immunity and mammals that heavily depend on adaptive immunity. The major mechanisms of the teleost fish innate immune response are suggested to be similar to mammals, although fine...

BACKGROUND: Infectious salmon anemia (ISA) virus (ISAV) is a pathogen of marine-farmed Atlantic salmon (Salmo salar); a disease first diagnosed in Norway in 1984. This virus, which was first characterized following its isolation in cell culture in 1995, belongs to the family Orthomyxoviridae, genus,...

BACKGROUND: Infectious salmon anaemia (ISA) virus (ISAV) is a pathogen of marine-farmed Atlantic salmon (Salmo salar); a disease first diagnosed in Norway in 1984. For over 25 years ISAV has caused major disease outbreaks in the Northern hemisphere, and remains an emerging fish pathogen because of t...

Infectious salmon anaemia virus (ISAV) is a marine orthomyxovirus of significant interest not only as a cause of a fatal disease of farmed Atlantic salmon resulting in severe economic losses to the aquaculture industry, but also as the only poikilothermic orthomyxovirus. ISAV targets vascular endoth...

As nonenveloped viruses, the aquareoviruses and orthoreoviruses are unusual in their ability to induce cell-cell fusion and syncytium formation. While an extraordinary family of fusion-associated small transmembrane (FAST) proteins is responsible for orthoreovirus syncytiogenesis, the basis for aqua...

Of 4,268 wild ducks sampled in Canada in 2005, real-time reverse transcriptase-PCR detected influenza A matrix protein (M1) gene sequence in 37% and H5 gene sequence in 5%. Mallards accounted for 61% of samples, 73% of M1-positive ducks, and 90% of H5-positive ducks. Ducks hatched in 2005 accounted ...

Routine laboratory diagnosis of infectious salmon anaemia virus (ISAV) infection is primarily by reverse transcription polymerase chain reaction (RT-PCR) because of the high sensitivity and rapid turnaround time of the test. This paper describes methods for highly reproducible absolute viral load me...

BACKGROUND: Infectious salmon anaemia (ISA) virus (ISAV), which causes ISA in marine-farmed Atlantic salmon, is an orthomyxovirus belonging to the genus Isavirus, family Orthomyxoviridae. ISAV agglutinates erythrocytes of several fish species and it is generally accepted that the ISAV receptor destr...

SUMMARYSome members of the ABC-transporter superfamily, such as P-glycoprotein and the multidrug resistance associated protein, may confer resistance to the avermectin subclass of macrocyclic lactones. The aim of this study was to examine the presence of ABC transporters in both sea lice (Lepeophthe...

BACKGROUND: Infectious salmon anaemia (ISA) is a viral disease of marine-farmed Atlantic salmon (Salmo salar) caused by ISA virus (ISAV), which belongs to the genus Isavirus, family Orthomyxoviridae. The virus is considered to be carried by marine wild fish and for over 25 years has caused major dis...
