Project description:The salmon gill poxvirus (SGPV) is a large DNA virus that infects gill epithelial cells in Atlantic salmon and is associated with acute high mortality disease outbreaks in aquaculture. The pathological effects of SGPV infection include gill epithelial apoptosis in the acute phase of the disease and hyperplasia of gill epithelial cells in surviving fish, causing damage to the gill respiratory surface. Transcriptome responses to virus were assessed in gills at different stages of disease

Project description:ISAV is one of the most dangerous pathogens causing high mortality of farmed Atlantic salmon. In this study, transcriptome responses to the virus were examined in vitro in Atlantic salmon head kidney cells culture (ASK). Poly(I:C), synthetic double-stranded RNA stimulating antiviral responses was used as a positive control.

Project description:Infectious pancreatic necrosis (IPN) is a serious viral disease that causes significant economic losses in salmon aquaculture. To characterize the host-pathogen relationship in IPN, we analysed transcriptional profiles of salmon head kidney (SHK-1) cells infected with infectious pancreatic necrosis virus (IPNV) at three timepoints over six days (at 1, 3 & 6 days post infection. The transcriptome was investigated using the TRAITS / SGP 16950-feature Atlantic salmon cDNA microarray, which is enriched for genes with functions related to the immune response.

Project description:Following an infection with a specific pathogen, the acquired immune system of many teleostean fish, including salmonids, is known to retain a specific memory of the infectious agent, which protects the host against subsequent infections. For example Atlantic salmon (Salmo salar), which have survived an infection with a low-virulence infectious salmon anemia virus (ISAV) isolate are less susceptible against subsequent infections with high-virulence ISAV isolates. A greater understanding of the mechanisms and immunological components involved in this acquired protection against ISAV is fundamental for the development of efficacious vaccines and treatments against this pathogen. To better understand the immunity components involved in this observed resistance, we have used an Atlantic salmon DNA microarray and RT-qPCR assays to study the global gene expression responses of preexposed Atlantic salmon (fish having survived an infection with a low-virulence ISAV isolate) during the course of a secondary infection with a high-virulence ISAV isolate

Project description:Vaccination of pre-smolt salmon with a plasmid encoding the structural polypeptide of salmonid alphavirus subtype 3 (SAV3) gives protection against infection and development of pancreas disease (PD) mediated with production of antibodies against the virus. The present study analysed transcript responses in the muscle to vaccination with this plasmid (pSAV), pcDNA3.3 was used as a control. pSAV and pcDNA3.3 had similar abilities to up-regulate typical type I IFN stimulated genes. In contrast, pSAV caused higher up-regulation of IFNγ and several IFNγ inducible genes. Compared to pcDNA3.3, pSAV also gave larger increase in transcripts of marker genes for B-cells, T-cells and antigen presenting cells (APCs), which suggests attraction of these cells and that their role in the adaptive immune response elicited by pSAV.

Project description:The aquatic orthomyxovirus infectious salmon anemia virus (ISAV) is an important pathogen for salmonid aquaculture, however little is known about protective and pathological host responses to infection. We have investigated intracellular responses during cytopathic ISAV infection in the macrophage-like Atlantic salmon kidney (ASK) cell line by microarray analysis (1.8K SFA2.0 immunochip) and a functional assay for glutathione. Gene transcription changed rapidly and consistently with time and with minor differences between two virus isolates. While several pro-inflammatory and antiviral immune genes were induced, genes involved in cell signaling and integrity were down-regulated, suggesting isolation of infected cells from cell-to-cell interaction and responses to external signals. Differential expression of genes regulating cell cycle and apoptosis implied opposite cues from host cell and virus. This was in pace with massive down-regulation of genes involved in biosynthesis and processing of nucleotides and nucleic acids. Significant down-regulation of several genes involved in metabolism of reactive oxygen species suggested increased oxidative stress, which was confirmed by a functional assay showing reduced levels of glutathione during infection. Testing of expression data against a microarray database containing diverse experiments revealed candidate marker genes for ISAV infection. Our findings provide novel insight into cellular host responses and determinants for acute cytopathic ISAV infection.

Project description:Infectious diseases among fish present an important economic burden for the aquaculture and fisheries industries around the world. For example, the infectious salmon anemia virus (ISAV) is known to infect farmed Atlantic salmon (Salmo salar), and results in millions of dollars of lost revenue to salmon farmers. Although improved management and husbandry practices over the last few years have minimized the losses and the number of outbreaks, the risk of new virulent isolates emerging is still a looming threat to the viability and sustainability of this industry. An understanding of the host-pathogen interactions at the molecular level during the course of an infection thus remains of strategic importance for the development of molecular tools and efficient vaccines capable of minimizing losses in the eventual case of a new outbreak. Using a 32 k cDNA microarray platform (cGRASP), we have studied various signaling pathways and immune regulated genes, activated or repressed, in Atlantic salmon head-kidney during the course of an ISAV infection. Gene expressions were measured at 5 different time-points: 6h, 24h, 3d, 7d and 16d post infection to get an overall view of changes as they occurred in time. The earliest time points showed only a few differentially expressed genes in infected fish, relative to controls, although as time progressed, many additional genes involved in key defense pathways were up-regulated including MHC type I, beta-2 microglobulin, TRIM 25 and CC-chemokine 19. During the latest stage of the infection process, many genes related to oxygen transportation were under-expressed, which correlates well with the anemia observed prior to death in Atlantic salmon infected with virulent strains of ISAV. Atlantic salmon smolts from 2 families of Atlantic salmon were IP injected with either 0.1mL of 10e5 TCID50 mL-1 of virus or 0.1mL of sham solution (L15 culture medium) and divided equally in four 1000 L tanks: 2 duplicate tanks containing ISAV injected fish and 2 duplicate control tanks containing sham solution injected fish. Four fish per family were sampled immediately prior to injection. An additional two fish per family per tank (four fish per family total) were sampled at 6h, 24h, 3d, 7d and 16d post injection. Head-kidney was dissected from each fish and used for microarray analysis. ISAV infected Atlantic salmon were compared to non-infected Atlantic salmon for each time-point.
