Ultrastructural insights into the replication cycle of salmon pancreas disease virus (SPDV) using salmon cardiac primary cultures (SCPCs)
J Fish Dis 2021 Dec;44(12):2031-2041.PMID:34424537DOI:10.1111/jfd.13518.
Salmon pancreas disease virus (SPDV) has been affecting the salmon farming industry for over 30 years, but despite the substantial amount of studies, there are still a number of recognized knowledge gaps, for example in the transmission of the virus. In this work, an ultrastructural morphological approach was used to describe observations after infection by SPDV of an ex vivo cardiac model generated from Atlantic salmon embryos. The observations in this study and those available on previous ultrastructural work on SPDV are compared and contrasted with the current knowledge on terrestrial mammalian and insect alphaviral replication cycles, which is deeper than that of SPDV both morphologically and mechanistically. Despite their limitations, morphological descriptions remain an excellent way to generate novel hypotheses, and this has been the aim of this work. This study has used a target host, ex vivo model and resulted in some previously undescribed features, including filopodial membrane projections, cytoplasmic stress granules or putative intracytoplasmic budding. The latter suggests a new hypothesis that warrants further mechanistic research: SPDV in salmon may have retained the capacity for non-cytolytic (persistent) infections by intracellular budding, similar to that noted in arthropod vectors of other alphaviruses. In the notable absence of a known intermediate host for SPDV, the presence of this pattern suggests that both cytopathic and persistent infections may coexist in the same host. It is our hope that the ultrastructural comparison presented here stimulates new research that brings the knowledge on SPDV replication cycle up to a similar level to that of terrestrial alphaviruses.
Isolation of salmon pancreas disease virus (SPDV) in cell culture and its ability to protect against infection by the 'wild-type' agent
Fish Shellfish Immunol 2001 Aug;11(6):505-22.PMID:11556480DOI:10.1006/fsim.2000.0330.
A Scottish salmon pancreas disease virus (SPDV) has been isolated and its optimum growth conditions determined. Although several fish cell lines have been tested, successful culture was achieved only with CHSE-214 cells. Cytopathic effects were observed after 5 days. The highest virus titres, calculated by microtitration assay, were reached at 15 degrees C. After 7-9 days post-inoculation, CHSE-214 cell supernatants contained between 10(7)-10(5) TCID50 ml(-1) The cultured isolate is chloroform- and pH 3.0-sensitive, and virions are 50-60 nm in diameter. These characteristics are similar to the Irish SPDV isolates. The culture isolate induced typical pancreas disease (PD) lesions in experimentally infected Atlantic salmon and convalescent fish were resistant to experimental infection with PD-infective kidney homogenates obtained by serial in vivo passages from a PD-infected farmed salmon (termed wild-type SPDV). Furthermore, fish immunised with the inactivated cultured virus were protected against a cohabitation challenge with the wild-type virus. Immunised fish sera showed virus-neutralising activity before challenge (7 weeks post-immunisation) and from 3-6 weeks post-challenge, when sera from non-immunised fish did not neutralise the virus. At 6 weeks post-cohabitation challenge, previously immunised fish had neutralising titres of up to 1:65. Following intraperitoneal (i.p.) challenge, immunised fish showed neutralising titres as high as 1:226 at 8 weeks post-challenge. Non-immunised fish injected i.p. with the wild-type virus developed serum-neutralising activity against the cultured isolate when sampled 8 weeks after infection, confirming an antigenic relationship between the wild-type and cultured virus. The results demonstrate that the tissue culture-adapted isolate of SPDV could be successfully used to protect against challenge by the wild-type virus and could therefore have potential use as an inactivated vaccine against PD.
Pathogenesis and immune response in Atlantic salmon (Salmo salar L.) parr experimentally infected with salmon pancreas disease virus (SPDV)
Fish Shellfish Immunol 2002 Jan;12(1):77-95.PMID:11866132DOI:10.1006/fsim.2001.0356.
Atlantic salmon parr were injected intraperitoneally with salmon pancreas disease virus (SPDV) grown on CHSE-214 cells. The viraemia, the histopathological changes in target organs and some immune parameters were taken at intervals up to 30 days post-infection (dpi). The earliest kind of lesion was necrosis of exocrine pancreas, appearing as soon as 2 dpi. It progressed towards complete tissue breakdown at 9 dpi before resolving gradually. Concurrent to this necrosis, a strong inflammatory response was in evidence from 9 dpi in the pancreatic area for a majority of fish. A necrosis of the myocardial cells of the ventricle occurred in infected fish mainly at 16 dpi and it faded thereafter. The monitoring of the plasma viral load showed a rapid haematogenous spreading of SPDV, peaking at 4 dpi, but also the absence of a secondary viraemia. No interferon (IFN) was detected following the infection of parr with SPDV, probably owing to an IFN activity in Atlantic salmon below the detection level of the technique. Neutralising antibodies against SPDV were in evidence from 16 dpi and they showed a time-related increasing titre and prevalence. The phagocytic activity in head-kidney leucocytes was always significantly higher in the infected fish than in the control fish, being particularly high by 9 dpi. Lysozyme and complement levels were both increased and they peaked significantly in the infected fish at 9 and 16 dpi respectively. These results demonstrated that an experimental infection of Atlantic salmon parr with SPDV provoked a stimulation of both specific and non-specific immunity with regards to the viraemia and the histopathology.
Biochemical characterization of salmon pancreas disease virus
J Gen Virol 2000 Mar;81(Pt 3):813-20.PMID:10675419DOI:10.1099/0022-1317-81-3-813.
Salmon pancreas disease virus (SPDV) has been shown to cause severe economic losses in farmed Atlantic salmon (Salmo salar) and has been reported to occur in Europe, Scandinavia and the United States. This paper describes the biochemical characterization of SPDV in terms of its RNA and protein composition. SPDV was purified by precipitation from infected Chinook salmon embryo (CHSE-214) cell-culture supernatant and sucrose density-gradient centrifugation. Fractions containing virus were identified by an immunodot blot assay using an SPDV-specific MAb. Two major proteins with molecular masses of approximately 55 and 50 kDa, putatively identified as the E1 and E2 alphavirus glycoproteins respectively, were detected when purified virus preparations were analysed by PAGE. Radiolabelling experiments indicated that SPDV infection of CHSE-214 cells did not shut-off host-cell protein synthesis, making attempts to identify virus-specific proteins unsuccessful. However, radioimmunoprecipitation assay (RIPA) experiments showed that two SPDV-specific MAbs reacted with a protein in the 50-55 kDa range. Northern blot hybridization with cloned cDNA probes indicated that infected cells contained RNA species of approximately 11.4 and 4 kb, which correspond to the genomic and subgenomic RNAs specified by SPDV. The results described are consistent with SPDV being characterized as an alphavirus.
Heritability of mortality in response to a natural pancreas disease (SPDV) challenge in Atlantic salmon, Salmo salar L., post-smolts on a West of Ireland sea site
J Fish Dis 2008 Dec;31(12):913-20.PMID:19017068DOI:10.1111/j.1365-2761.2008.00982.x.
Pancreas disease (PD) is an economically important disease of European farmed Atlantic salmon. It can cause significant losses because of morbidity, mortality and reduced production. The disease is caused by an alphavirus, known as salmon PD virus (SPDV) or salmonid alphavirus subtype 1 in Ireland. To examine whether it is possible to improve the natural resistance of Atlantic salmon to SPDV by selective breeding, 6000 genotyped, tagged, pedigreed fish from 150 full-sib families were exposed to a natural challenge during 2005 in a sea cage on a commercial salmon farm in the West of Ireland. Histopathological and serological examination was performed weekly on a proportion of all moribund fish to determine the onset of the infection and the likely cause of death. Heritabilities and genetic correlations are presented for resistance to a natural PD challenge and smolt input weight. The results indicate that the susceptibility of salmon to SPDV could be reduced by selective breeding based on the survival in a natural challenge to the virus.
