Genetic diversity of equine arteritis virus. (1/87)
Equine arteritis viruses (EAV) from Europe and America were compared by phylogenetic analysis of 43 isolates obtained over four decades. An additional 22 virus sequences were retrieved from GenBank. Fragments of the glycoprotein G(L) and the replicase genes were amplified by RT-PCR, prior to sequencing and construction of phylogenetic trees. The trees revealed many distinctive lineages, consistent with prolonged diversification within geographically separated host populations. Two large groups and five subgroups were distinguished. Group I consisted mainly of viruses from North America, whilst group II consisted mainly of European isolates. In most instances, where the geographic origin of the viruses appeared to be at variance with the phylogenetically predicted relationships, the horses from which the viruses were recovered had been transported between Europe and America or vice versa. Analysis of the replicase gene revealed similar phylogenetic relationships although not all of the groups were as clearly defined. Virus strains CH1 (Switzerland, 1964) and S1 (Sweden, 1989) represented separate 'outgroups' based on analysis of both genomic regions. The results of this study confirm the value of the G(L) gene of EAV for estimating virus genetic diversity and as a useful tool for tracing routes by which EAV is spread. In addition, computer-assisted predictions of antigenic sites on the G(L) protein revealed considerable variability among the isolates, especially with respect to regions associated with neutralization domains. (+info)Genetic divergence with emergence of novel phenotypic variants of equine arteritis virus during persistent infection of stallions. (2/87)
The persistently infected carrier stallion is the critical natural reservoir of equine arteritis virus (EAV), as venereal infection of mares frequently occurs after breeding to such stallions. Two Thoroughbred stallions that were infected during the 1984 outbreak of equine viral arteritis in central Kentucky subsequently became long-term EAV carriers. EAV genomes amplified from the semen of these two stallions were compared by sequence analysis of the six 3' open reading frames (ORFs 2 through 7), which encode the four known structural proteins and two uncharacterized glycoproteins. The major variants of the EAV population that sequentially arose within the reproductive tract of each carrier stallion varied by approximately 1% per year, and the heterogeneity of the viral quasispecies increased during the course of long-term persistent infection. The various ORFs of the dominant EAV variants evolved independently, and there was apparently strong selective pressure on the uncharacterized GP3 protein during persistent infection. Amino acid changes also occurred in the V1 variable region of the GL protein. This region has been previously identified as a crucial neutralization domain, and selective pressures exerted on the V1 region during persistent EAV infection led to the emergence of virus variants with distinct neutralization properties. Thus, evolution of the EAV quasispecies that occurs during persistent infection of the stallion clearly can influence viral phenotypic properties such as neutralization and perhaps virulence. (+info)Equine arteritis virus derived from an infectious cDNA clone is attenuated and genetically stable in infected stallions. (3/87)
Virus derived from an infectious cDNA clone of equine arteritis virus (EAV030H) was intranasally inoculated into two stallions, neither of which subsequently developed clinical manifestations of equine viral arteritis (EVA). Virus was isolated from nasal swabs and mononuclear cells collected from both stallions +info)Genetic stability of equine arteritis virus during horizontal and vertical transmission in an outbreak of equine viral arteritis. (4/87)
An imported carrier stallion (A) from Europe was implicated in causing an extensive outbreak of equine viral arteritis (EVA) on a Warmblood breeding farm in Pennsylvania, USA. Strains of equine arteritis virus (EAV) present in the semen of two carrier stallions (A and G) on the farm were compared to those in tissues of foals born during the outbreak, as well as viruses present in the semen of two other stallions that became persistently infected carriers of EAV following infection during the outbreak. The 2822 bp segment encompassing ORFs 2-7 (nt 9807-12628; which encode the G(S), GP3, GP4, G(L), M and N proteins, respectively) was directly amplified by RT-PCR from semen samples and foal tissues. Nucleotide and phylogenetic analyses confirmed that virus present in the semen of stallion A initiated the outbreak. The genomes of viruses present in most foal tissues (10/11) and serum from an acutely infected mare collected during the outbreak were identical to that of virus present in the lung of the first foal that died of EVA. Virus in the placenta of one foal differed by one nucleotide (99.9% identity) from the predominant outbreak virus. The relative genetic stability of viruses that circulated during the outbreak contrasts markedly with the heterogeneous virus populations variously present in the semen of persistently infected stallions on the farm. These findings are consistent with the hypothesis that the carrier stallion can be a source of genetic diversity of EAV, and that outbreaks of EVA can be initiated by the horizontal aerosol transmission of specific viral variants that occur in the semen of particular carrier stallions. (+info)The open reading frame 3 of equine arteritis virus encodes an immunogenic glycosylated, integral membrane protein. (5/87)
Open reading frame 3 (ORF 3) of equine arteritis virus (EAV) is predicted to encode a glycosylated membrane protein (GP3) that is uncharacterized. ORF 3 of the American Type Culture Collection strain of EAV was in vitro transcribed and the encoded GP3 protein was in vitro translated with and without canine microsomal membranes. The GP3 protein was approximately 17 kDa after in vitro translation without canine microsomal membranes whereas the glycosylated form, after translation with microsomal membranes, was a diffuse band of 36-42 kDa, indicating that the GP3 protein is extensively glycosylated. Deglycosylation reduced the GP3 protein to approximately 17 kDa, the same size as that translated without microsomal membranes, indicating that the signal sequence was not cleaved. The EAV GP3 protein was membrane associated and not released as a soluble protein, in marked contrast to the ORF 3-encoded proteins of some other arteriviruses. The GP3 protein was protected from protease digestion in closed membrane vesicles, suggesting that the protein extends into the membrane vesicles and is anchored by the N-terminal signal sequence, a C-terminal hydrophobic domain, or both, but does not span the membrane three times. A GP3 protein lacking the C-terminal transmembrane domain remained membrane associated, indicating that this terminus is not a necessary membrane anchor. Sera from stallions persistently infected with EAV and horses immunized repeatedly with the modified live EAV vaccine contained antibodies specific for the GP3 protein. The data indicate that the GP3 protein is an extensively glycosylated membrane protein that is immunogenic during some EAV infections. (+info)Neuropathogenicity and sensitivity to antibody neutralization of lactate dehydrogenase-elevating virus are determined by polylactosaminoglycan chains on the primary envelope glycoprotein. (6/87)
Common strains of lactate dehydrogenase-elevating virus (LDV, an arterivirus), such as LDV-P and LDV-vx, are highly resistant to antibody neutralization and invariably establish a viremic, persistent, yet asymptomatic, infection in mice. Other LDV strains, LDV-C and LDV-v, have been identified that, in contrast, are highly susceptible to antibody neutralization and are incapable of a high viremic persistent infection, but at the same time have gained the ability to cause paralytic disease in immunosuppressed C58 and AKR mice. Our present results further indicate that these phenotypic differences represent linked properties that correlate with the number of N-glycosylation sites associated with the single neutralization epitope on the short ectodomain of the primary envelope glycoprotein, VP-3P. The VP-3P ectodomains of LDV-P/vx possess three N-glycosylation sites, whereas those of LDV-C/v lack the two N-terminal sites. We have now isolated four independent neutralization escape variants of neuropathogenic LDV-C and LDV-v on the basis of their ability to establish a high viremic persistent infection in mice. The VP-3P ectodomains of all four variants had specifically regained two N-glycosylation sites concomitant with decreased immunogenicity of the neutralization eptitope and decreased sensitivity to antibody neutralization as well as loss of neuropathogenicity. (+info)IFN-gamma-independent IgG2a production in mice infected with viruses and parasites. (7/87)
After infection with some viruses and intracellular parasites, antibody production is restricted to IgG2a. We first observed that, whereas live viruses such as lactate dehydrogenase-elevating virus (LDV) or mouse adenovirus induced mostly an IgG2a response, a large proportion of antibodies produced against killed viruses were IgG1. This IgG1 antiviral response was suppressed when live virions were added to inactivated viral particles. These results indicate that the IgG2a preponderance is related to the infectious process itself rather than to the type of antigen involved. Since IFN-gamma is known to stimulate IgG2a production by activated B lymphocytes and to be secreted after infection, we examined the role of this cytokine in the antibody isotypic distribution caused by LDV. Most IgG2a responses were relatively unaffected in mice deficient for the IFN-gamma receptor or treated with anti-IFN-gamma antibody. A similar IFN-gamma-independent IgG2a secretion was observed after infection with the parasites Toxoplasma gondii and Trypanosoma cruzi. However, the IFN-gamma-independent IgG2a production triggered by infection still required the presence of functional T(h) lymphocytes. Therefore, signal(s) other than IFN-gamma secretion may explain the T(h)-dependent isotypic bias in antibody secretion triggered by viruses and parasites. (+info)Effects of chlorine, iodine, and quaternary ammonium compound disinfectants on several exotic disease viruses. (8/87)
The effects of three representative disinfectants, chlorine (sodium hypochlorite), iodine (potassium tetraglicine triiodide), and quaternary ammonium compound (didecyldimethylammonium chloride), on several exotic disease viruses were examined. The viruses used were four enveloped viruses (vesicular stomatitis virus, African swine fever virus, equine viral arteritis virus, and porcine reproductive and respiratory syndrome virus) and two non-enveloped viruses (swine vesicular disease virus (SVDV) and African horse sickness virus (AHSV)). Chlorine was effective against all viruses except SVDV at concentrations of 0.03% to 0.0075%, and a dose response was observed. Iodine was very effective against all viruses at concentrations of 0.015% to 0.0075%, but a dose response was not observed. Quaternary ammonium compound was very effective in low concentration of 0.003% against four enveloped viruses and AHSV, but it was only effective against SVDV with 0.05% NaOH. Electron microscopic observation revealed the probable mechanism of each disinfectant. Chlorine caused complete degeneration of the viral particles and also destroyed the nucleic acid of the viruses. Iodine destroyed mainly the inner components including nucleic acid of the viruses. Quaternary ammonium compound induced detachment of the envelope of the enveloped viruses and formation of micelle in non-enveloped viruses. According to these results, chlorine and iodine disinfectants were quite effective against most of the viruses used at adequately high concentration. The effective concentration of quaternary ammonium compound was the lowest among the disinfectants examined. (+info)

PRRSV19
- In this study, we investigated the potential effect of curcumin on early stages of PRRSV infection. (biomedcentral.com)
- Curcumin inhibited infection of Marc-145 cells and porcine alveolar macrophages (PAMs) by four different genotype 2 PRRSV strains, but had no effect on the levels of major PRRSV receptor proteins on Marc-145 cells and PAMs or on PRRSV binding to Marc-145 cells. (biomedcentral.com)
- However, curcumin did block two steps of the PRRSV infection process: virus internalization and virus-mediated cell fusion. (biomedcentral.com)
- Our results suggested that an inhibition of genotype 2 PRRSV infection by curcumin is virus strain-independent, and mainly inhibited by virus internalization and cell fusion mediated by virus. (biomedcentral.com)
- Therefore, we evaluated curcumin as an anti-PRRSV agent in Marc-145 cells and PAM and found it inhibited PRRSV infection by preventing virus internalization and virus-mediated cell fusion. (biomedcentral.com)

- And inhibition of the complement system likely attenuated the lung damage during HP-PRRSV infection. (ijbs.com)
- In vivo , PRRSV productive infection occurs predominately in alveolar macrophages of the lung [ 3 ], followed by viremia and subsequent interstitial pneumonia within 3 days [ 4 ]. (ijbs.com)
- It was hypothesized that respiratory pathology, especially lung damage during PRRSV infection, results from an overproduction of pro-inflammatory cytokines in the lungs [ 5 ]. (ijbs.com)
- Genome-wide transcriptional responses of lungs of Landrace×Yorkshire crossbred piglets to a classical North American type PRRSV strain infection was analyzed by Solexa/Illumina's Digital Gene Expression (DGE) System, which is a tag-based high-throughput transcriptome sequencing method [ 6 ]. (ijbs.com)
- This systematic analysis of the pulmonary gene expression profiles suggested that upregulation expression of pro-inflammatory cytokines, chemokines, adhesion molecules and inflammatory enzymes and inflammatory cells, antibodies, complement activation were likely to result in the development of inflammatory responses during PRRSV infection processes [ 6 ]. (ijbs.com)
- PRRSV infection is mediated by porcine CD163 (pCD163). (ijbs.com)
- Scavenger receptor cysteine-rich domain 5 coded by exon 7 of pCD163 is essential for PRRSV infection. (ijbs.com)
- Our results demonstrated that CD163 exon 7 deletion confers resistance to HP-PRRSV infection without impairing the biological functions of CD163. (ijbs.com)
- More recently, there is a developing recognition of the cost of PRRSV infection in growing pigs. (thepigsite.com)
