N2 - Comparative sequence analysis of a series of strains of equine arteritis virus (EAV) of defined virulence for horses, ranging from the horse-adapted virulent Bucyrus (VB) strain to a fully attenuated vaccine strain derived from it, identified 13 amino acid substitutions associated with attenuation. These include 4 substitutions in the replicase proteins and 9 in the structural proteins. Using reverse genetic techniques, these amino acid substitutions were introduced into a virulent infectious cDNA clone pEAVrVBS derived from the VB strain of EAV. Inoculation of horses with the recombinant viruses clearly demonstrated that changes in either the replicase ...

N2 - A one-tube real-time TaqMan® reverse transcription-polymerase chain reaction (RT-PCR) assay was developed for the detection of equine arteritis virus (EAV). The test was validated using the seminal plasma and nasal secretions of infected horses that were proven to contain EAV by traditional virus isolation in rabbit kidney thirteen (RK-13) cells, as well as a variety of cell culture-propagated European and North American strains of EAV. The primers and a fluorogenic TaqMan® probe were designed to amplify and detect a highly conserved region of open reading frame 7 (ORF7) of EAV. The real-time TaqMan® PCR assay detected EAV RNA in all samples that were confirmed to contain infectious EAV by virus isolation. ...

cDNA copies of the M and N genes of equine arteritis virus (EAV) isolates were synthesized by reverse transcription followed by polymerase chain reaction amplification. The cDNA was subjected to a cycle sequencing strategy using Taq polymerase, and the nucleotide and derived amino acid sequences of 10 virus isolates were compared. The M and N genes of all isolates had the same initiation and termination sites as the prototype Bucyrus strain and the encoded proteins were conserved between viruses. Comparison of nucleotide sequence homologies and phylogenetic tree analysis implied the existence of three EAV variants originating from the U.S.A. (Bucyrus), Austria (Vienna) and Switzerland (Bibuna), and suggested that RNA recombination between EAV isolates may have occurred.

Previous studies in our laboratory have identified equine CXCL16 (EqCXCL16) to be a candidate molecule and possible cell entry receptor for equine arteritis virus (EAV). In horses, the CXCL16 gene is located on equine chromosome 11 (ECA11) and encodes a glycosylated, type I transmembrane protein with 247 amino acids. Stable transfection of HEK-293T cells with plasmid DNA carrying EqCXCL16 (HEK-EqCXCL16 cells) increased the proportion of the cell population permissive to EAV infection from | 3% to almost 100%. The increase in permissiveness was blocked either by transfection of HEK-EqCXCL16 cells with small interfering RNAs (siRNAs) directed against EqCXCL16 or by pretreatment with guinea pig polyclonal antibody against EqCXCL16 protein (Gp anti-EqCXCL16 pAb). Furthermore, using a virus overlay protein-binding assay (VOPBA) in combination with far-Western blotting, gradient-purified EAV particles were shown to bind directly to the EqCXCL16 protein in vitro.

Equine arteritis virus (EAV) is a positive stranded RNA virus that infects horses worldwide. Sporadic respiratory disease and sudden death in foals, abortion in mares, and mild or subclinical infections in adult horses have been described resulting from this infection. Adult stallions may become chronically infected; they can become a reservoir and spread the virus via their semen. VetPCR EAV Detection Kit is the direct detection of Equine arteritis virus on the basis of a genetic database, so it can diagnose very fast and accurately. It can amplify only specific gene using the PCR (Polymerase Chain Reaction) method, and take only 3 hours for detection. Therefore, it is a very fast, accurate, reliable technique.

Serological analysis of blood samples submitted to the Animal Health Trust showed that during 1995, 185 of 9203 unvacdnated horses (2.0 per cent) tested positive for antibodies to equine arteritis virus (EAV), and that during 1996,46 of 8851 unvaccinated horses (0.52 per cent) tested positive. During both years thoroughbreds were the predominant breed tested and only a small proportion of these (<0.3 per cent), consisting predominantly of imported mares, were seropositive. In contrast, among standardbred horses, from which samples were actively solicited in 1995,84 of 454 (18.5 per cent) were seropositive. Among standardbreds there was a difference in prevalence between types of horses, with 3.7 per cent of racing horses, 25 per cent of non-radng horses and 41 per cent of stallions testing seropositive. Investigations of seropositive stallions identified during 1994 and 1995 demonstrated that clinically inapparent equine viral arteritis (EvA) had occurred previously in the uKC Of 50 ...

Udeni Balasuriya, a professor at the University of Kentucky Maxwell H. Gluck Equine Research Center, recently received $2.9 million to identify the genetic factors responsible for establishment of the equine arteritis virus (EAV) carrier state in stallions. The five-year grant was awarded by the U. S. Department of Agriculture-Agriculture and Food Research Initiative.. According to Nancy Cox, associate dean for research in UKs College of Agriculture and administrative leader for UKs Ag Equine Programs, Balasuriyas grant was ranked the highest in its category, unusual for a USDA grant program that normally targets food animals.. This is one of the largest grants awarded in the College of Agriculture in the last year, she said, and is a special kind that includes funds for getting results out to the public in the fastest, most efficient way.. Outbreaks of equine viral arteritis (EVA) result in significant economic losses to the equine industry due to high rates of foal loss in pregnant mares, ...

The change of just four nucleotides in the CXCL16 gene is all that is necessary to determine whether or not stallions are likely to become long-term carriers of EAV. Sanjay Sarkar, Ernest Baily and Udeni Balasuriya of the University of Kentucky, Lexington, and colleagues report these findings Dec. 8, 2016 in PLOS Genetics.

Equine arteritis virus (EAV) and Porcine reproductive and respiratory syndrome virus (PRRSV) are enveloped RNA viruses belonging to the family Arteriviridae. EAV infection leads to abortion and respiratory illness in horses. PRRSV causes persistent infections in pigs, which is one of the main reasons for the economic losses in the swine industry. The glycoprotein complex Gp2/3/4 and Gp5/M are essential for cell entry and budding, respectively. PRRSV and EAV Gp2/3/4 ectodomains were co-expressed to determine their complex formation in insect cells. The results revealed that PRRSV Gp2/3/4 proteins secreted into the cell culture supernatant as a disulphide linked complex. In contrast, Gp3 of EAV was expressed, but not associated with Gp2/4. The Gp2/3/4 proteins of both PRRSV and EAV are attached to the membrane through their C-terminal hydrophobic transmembrane region as they were secreted when it is removed. This result showed that all the proteins contain type I membrane topology except EAV Gp3 since

Summary Reasons for performing study:A serological study conducted in 1995 revealed that 7 stallions at the Lipizzaner Centre, Gauteng, South Africa, were seropositive for antibody to equine arteritis virus (EAV). A Lipizzaner stallion imported into South Africa from Yugoslavia in 1981 had previously (1988) been confirmed to be an EAV carrier. Despite being placed under life-long breeding quarantine, EAV had been transmitted between stallions at the Lipizzaner Centre. Objectives: To investigate the phylogenetic relationships between the strain of EAV shed in the semen of the original carrier stallion and strains recovered from the semen of 5 other stallions; and to investigate the means whereby lateral transmission of EAV occurred among 7 in-contact, nonbreeding stallions at the Centre. Methods: EAV was isolated from semen collected from the seropositive stallions using RK-13 cells. Viral RNA was reverse transcribed and amplified by polymerase chain reaction using ORF5-specific primers, ...

One hallmark of the PRRS virus in swine is its extremely high genetic diversity. This phenomenon has important implications for disease diagnosis and prevention and is one of the major causes of the partial or complete lack of protection against re-infections.. The PRRS virus is an RNA virus that belongs to the genus Arterivirus, the only genus in the family Arteriviridae, in the order Nidovirales. The PRRS virus contains a non-segmented, single-stranded, positive-sense RNA genome. The RNA genome is composed of ten open reading frames (ORFs).. Since the first outbreaks of PRRS in swine in America and Europe, two PRRS virus genotypes have been designated: European or Type 1 (prototype Lelystad virus) and North-American or Type 2 (prototype VR-2332). Interestingly, similarity between both prototype nucleotide sequences is as low as 55%. More importantly, intratype pairwise nucleotide sequence variation exceeds 20% (up to 30% in type 1 and around 21% in type 2).. A significant number of subtypes ...

Diagnosing horse ailments requires a vet. (Click here for a list of Florida veterinarians by county). Equine viral arteritis (EVA) is a disease of horses caused by an RNA virus of the genus Arterivirus. The virus which causes EVA was first isolated from horses in Ohio in 1953 but the disease has afflicted equine animals worldwide for centuries. It has been more common in some breeds of horses in the United States, but there is no breed immunity. There is no known human hazard.. Arteriviruses are small, enveloped, animal viruses with an icosahedral core containing a positive-sense RNA genome. The family includes Equine arteritis virus (EAV), porcine reproductive and respiratory syndrome virus (PRRSV), lactate dehydrogenase elevating virus (LDV) of mice and simian haemorrhagic fever virus (SHFV).. ...

Nodaviridae is a family of non-enveloped isometric viruses with bipartite positive-sense RNA genomes. The Nodaviridae family consists of two genera: alpha- and beta-nodavirus. Alphanodaviruses usually infect insect cells. Some commercially available insect cell lines have been latently infected by Alphanodaviruses. A non-enveloped small virus of approximately 30 nm in diameter was discovered co-existing with a recombinant Helicoverpa armigera single nucleopolyhedrovirus (Hear NPV) in Hz-AM1 cells. Genome sequencing and phylogenetic assays indicate that this novel virus belongs to the genus of alphanodavirus in the family Nodaviridae and was designated HzNV. HzNV possesses a RNA genome that contains two segments. RNA1 is 3038 nt long and encodes a 110 kDa viral protein termed protein A. The 1404 nt long RNA2 encodes a 44 kDa protein, which exhibits a high homology with coat protein precursors of other alphanodaviruses. HzNV virions were located in the cytoplasm, in association with cytoplasmic membrane

In this study, we attempted to induce mutations in the MN strain of HIV-1 by subjecting the virus to the immunological selective pressure associated with growth in the presence of human serum with high NA activity directed predominately against the V3 region neutralization determinant. We hypothesized that this selective pressure would result in a mutation(s) in the V3 neutralization determinant itself and that the mutation(s) would result in selective resistance to neutralization by the serum used for the selection process and other sera that reacted selectively with the MN V3 neutralization determinant. The four different NR viruses so derived were found to be broadly resistant to neutralization by all of the human sera that we tested, including some that had NA activity that could not be demonstrated to be directed against the V3 determinant by peptide blocking experiments. Sequencing of the PCR DNA spanning the V3 regions of the four different NR viruses derived by this procedure did not ...

2014: New Zealand celebrated freedom from equine viral arteritis (EVA). EVA is a serious cause of abortion in horses and has significant trade implications for the horse breeding industry. Eradication of EVA was made possible by more than 20 years of work at Wallaceville, testing breeding horses and preventing further spread of the disease. 2013: The MPI laboratory at Wallaceville carried out more than 30,000 tests on a wide range of samples from farm animals to companion animals and other species. Results were used in 286 exotic disease investigation cases, surveillance work, and certifying animals as disease-free for trade. 2013: an epidemic of anaemia in Northland cattle was identified at Wallaceville as being caused by Theileria orientalis Ikeda. This led to a major disease control programme involving MPI and the beef and dairy industries. Wallaceville scientists developed new, faster and more accurate tests for the new strain. This test has now been distributed to commercial veterinary ...

Coronaviruses constitute the subfamily Orthocoronavirinae, in the family Coronaviridae, order Nidovirales, and realm Riboviria. They are enveloped viruses with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 27 to 34 kilobases, the largest among known RNA viruses. The name coronavirus is derived from the Latin corona, meaning crown or halo, which refers to the characteristic appearance reminiscent of a crown or a solar corona around the virions (virus particles) when viewed under two-dimensional transmission electron microscopy, due to the surface being covered in club-shaped protein spikes.. ...

Viral respiratory infections are common in horses; the most notable are equine herpesvirus infection, equine influenza, and equine viral arteritis. The clinical manifestations are similar and include pyrexia, serous nasal discharge, submandibular lymphadenopathy, anorexia, and cough. In addition to respiratory disease, equine herpesvirus type 1 (EHV-1) can cause abortion and neurologic disease, and equine herpesvirus type 5 (EHV-5) is a newly recognized cause of multinodular pulmonary fibrosis. Equine viral arteritis produces respiratory disease, vasculitis, and abortion. Equine herpesvirus type 2 (EHV-2), equine rhinitis virus, and reovirus are ubiquitous viral respiratory pathogens, and infection results in minimal clinical disease. Adenovirus pneumonia is most often seen in association with severe combined immunodeficiency in Arabian foals. Hendra virus () is a zoonotic disease of horses identified in Australia; it is rapidly fatal in horses, and close contact is necessary for disease transmission.

On average it takes 44 months from onset of symptoms to diagnose Takayasu arteritis. Because of its rarity and the often subtle physical findings, Takayasu arteritis frequently fails to enter the differential diagnosis for patients with fever of unknown origin (FUO). Thus it is critical to consider Takayasu arteritis in patients under 40 with FUO, aortic regurgitation, hypertension, or absent pulses. Rarely, patients older than 40 years of age meet the criteria for Takayasu arteritis because of a prolonged pre-diagnostic period or late onset of symptoms. In this case, giant cell arteritis may be indistinguishable from Takayasu arteritis; however, initial treatment for both is nearly identical ...

The most important viral respiratory diseases affecting horses are equine herpesvirus, equine influenza, and equine viral arteritis. Equine rhinitis virus and equine adenovirus-1 infection can be a cause of equine respiratory disease too.. The ISU VDL offers PCR assays for detecting all of these respiratory viruses. EHV-1, EHV-4 and EAV are also the most common viral causative agents for equine abortion. Equine herpes myeloencephalopathy (EHM) outbreaks have increased in recent years. The EHV1 neuropathotyping PCR is able to differentiate DNApol (ORF30) D/N752 strains; the D752 strains are strongly associated with EHM occurrence. EHV-3 is the etiologic agent of the reproductive disease - equine coital exanthema.. The ISU VDL also offers virus isolation for the above listed equine viruses..

Takayasus arteritis is a chronic inflammatory condition that affects the aorta, the largest blood vessel in the body, and its branches. Inflammation causes segments of the vessels to become narrowed, blocked, or even stretched, possibly resulting in aneurysms. The disease is very rare but most commonly occurs in young Asian women. Symptoms may include arm pain with use, decreased or absent pulses, lightheadedness or dizziness, headaches, and visual disturbances. Many individuals with Takayasu arteritis, however, have no apparent symptoms despite disease activity. Additionally, current tests used to measure vessel inflammation are considered unreliable and inconsistent. It is therefore very difficult to determine the extent of disease activity in a person with Takayasus arteritis. This study will use novel scientific methods to establish new biomarkers that can be used to monitor disease activity in individuals with Takayasus arteritis. These biomarkers may be used to help direct clinical ...

Epstein-Barr virus (EBV) is a gammaherpesvirus that causes infectious mononucleosis and is associated with B cell and epithelial cell cancers. EBV is an enveloped virus and therefore requires the fusion of the viral and cellular membrane to infect cells. The specificity of cell infection and membrane fusion triggered by the virus is for B cell entry is governed by four viral glycoproteins (gH, gL, gB and gp42), whereas EBV entry into epithelial cells requires three viral glycoproteins (gH, gL, and gB). The gB protein is thought to play the primary role in mediating membrane fusion, receiving activating signals from the other proteins after receptor binding to cells. The gH and gL proteins form a complex that also associates with gp42, and this three-way complex is necessary for binding receptors on B cells and triggering their infection. However, for epithelial cells, gHgL interacts directly with EphA2 triggering EBV membrane fusion and entry, presumably by activating gB. These triggering ...

Book list Geneticist Seymour Benzer is little known outside his specialty, but Weiner lifts him from obscurity in this exploration of Benzers study of the genetic contribution to behavior. The effort antedates Benzers entry onto the molecular biological stage in the late 1940s. Weiner narrates the discovery of the gene in the 1910s by T. H. Morgan. Morgans Fly Room became the generic label for the labs of geneticists, since that is where they studied their favorite organism, fruit flies. Following the discovery of DNAs double-helix structure, Benzer made a revolutionary impact by showing how genes could be split, and, further, how they could be mapped. But because Benzer was not a self-promoter and didnt write popular books, his achievements werent widely trumpeted, as were those of James Watson, an accomplished self-promoter. Content as a pure researcher, Benzer became interested in the nature-versus-nurture question, and he and the young researchers he mentored established the ...
