N2 - The genomic diversity among isolates of suid herpesvirus 1 (SHV-1) collected in the same herd and among clones from the same isolate was studied by restriction fragment pattern (RFP) analysis using BamHI. Tentatively defining a field strain as a transmissible entity, it was concluded that strains of SHV-1 commonly comprise distinguishable genomic variants. Contrary to the hypothesis of genomic lability, it is suggested that the pool of variants is sufficiently stable to specifically characterize a strain. The impact of the results on epizootiological methods based on identification of field isolates is discussed in connection with Aujeszkys disease in Denmark..

The aim of the study was to analyse the prevalence of single-reactor (SR) pigs in Poland, to attempt an explanation for this phenomenon, and to assess whether the occurrence of SR pigs could create problems for a successful Aujeszkys disease virus (ADV) eradication programme in Poland. A total of 6494 ADV gE antibody positive/doubtful sera were retested by gB ELISA and subsequently by virus neutralisation test (VNT) to confirm the results of the glycoprotein E (gE) ELISA. Amongst the serum samples tested, 5.9% could be classified as being taken from SR pigs, as was shown by gE ELISA positive/doubtful results, which were not confirmed by negative findings in gB ELISA and VNT. It means that the observed SR phenomenon was due to a false positive/doubtful reaction in gE ELISA. This finding was strongly supported by the fact that the serum samples were taken from the animals from herds without any previous or subsequent history of Aujeszkys disease. The low percentage of SR pigs does not seem to ...

Effects of pseudorabies virus (PRV) infection were studied on the reproductive tracts of young boars and pregnant gilts. The boars were challenged with virulent PRV which was inoculated intrapreputially (IP) in some and intranasally (IN) in others. Pseudorabies virus was isolated from the prepuce of two intrapreputially inoculated boars twelve days post-inoculation (PI), but not from the semen of any boars. Microscopic changes were typified by lympho-histiocytic aggregates, and were primarily limited to the prepuce and penis. Microscopic lesions in central nervous system (CNS) of these boars were characterized by a lympho-histiocytic meningoencephalitis and ganglioneuritis. All of the boars experienced poor semen quality PI for a period of one to two weeks. Semen changes were observed 10-14 days PI, they were characterized by bent, coild and reverse tails. Head abnormalities were manifested four weeks after inoculation. The changes were typified by knobbed (cystic acrosome), detached and double heads;In

In this thesis, some effects of pseudorabies virus infection on RNA metabolism in BHK-21/C15 cells were examined; in particular the production of 4S RNA and 5S RNA was studied. 1. The concentration of uridine in the medium that allows maximum incorporation of isotopically-labelled uridine into RNA in CI5 cells was determined. 2. A 10% polyacrylamide gel electrophoresis system was calibrated and used to fractionate low molecular weight cytoplasmic RNA, excellent separation between 5S RNA and 4S RNA being obtained. 5. Infection of exponentially-growing cells with pseudorabies virus caused a steady decrease (to 15% of the uninfected level) in incorporation of 3H uridine into RNA by 5 hours after infection. The production of cytoplasmic 28S and 18S RNAs was found to be most strongly inhibited while the production of 4S and 5S RNAs was much less affected; the decrease in synthesis of 4S RNA from either total cytoplasm, cell sap or ribosomes was found to be virtually identical. 4. In some experiments, ...

Aujeszkys disease, usually called pseudorabies in the United States, is a viral disease in swine that has been endemic in most parts of the world. It is caused by Suid herpesvirus 1 (SuHV1). Aujeszkys disease is considered to be the most economically important viral disease of swine in areas where classical swine fever (hog cholera) has been eradicated. Other mammals, such as cattle, sheep, goats, cats, dogs, and raccoons, are also susceptible. The disease is usually fatal in these animal species. The term pseudorabies is found inappropriate by many people, as SuHV1 is a herpesvirus and not related to the rabies virus. Research on SuHV1 in pigs has pioneered animal disease control with genetically modified vaccines. SuHV1 is now used in model studies of basic processes during lytic herpesvirus infection, and for unravelling molecular mechanisms of herpesvirus neurotropism. In 1902, a Hungarian veterinarian, Aladár Aujeszky, demonstrated a new infectious agent in a dog, ox, and cat, and ...

Age-dependent differences in pseudorabies virus neuropathogenesis and associated cytokine expression: The severity of clinical symptoms induced by pseudorabies

The alpha herpesviruses have evolved to enter the peripheral nervous systems of their natural hosts and establish a quiescent infection (latency) in peripheral ganglia that can be reactivated at a later time. The spread of infection is through chains of synaptically connected neurons. The biology of pseudorabies virus (PRV), a swine herpesvirus with a very broad host range (essentially all mammals except higher primates), is of some interest for several reasons. In all of its hosts except swine, PRV infection is neuroinvasive and lethal. In addition, certain attenuated mutants can spread only in one direction in chains of synaptically connected neurons. These strains are used in tracing neural circuitry in a variety of mammals and bird embryos. The viral genome inside capsids is moved long distances in axons in a controlled fashion on microtubules. Sorting of virion components into axons controls the directional, neuronal spread of infection of alpha herpesviruses. We have been studying two ...

Während des Replikationszyklus der Herpesviren vermittelt ein heterodimerer Proteinkomplex, welcher als nuclear egress complex (NEC) bezeichnet wird, den Transport neu synthetisierter Nukleokapside vom Zellkern ins Zytoplasma. Ziel dieser Arbeit war es, die molekularen Grundlagen des viralen Kernaustritts weiter aufzuklären und funktionelle Domänen in den NEC-Komponenten, welche beim Pseudorabies Virus als pUL31 und pUL34 bezeichnet werden, zu ermitteln. Bereits durchgeführte Analysen konnten zeigen, dass die Transmembrandomäne des pUL34, die für die Verankerung des NEC an der Kernmembran verantwortlich ist, bei HSV-1 und PrV durch heterologe Sequenzen ausgetauscht werden kann, ohne dass dabei die Proteinfunktion während des viralen Kernaustritts inhibiert wird. Beim PrV pUL34 kann sogar eine Substitution der 50 C-terminalen Aminosäuren toleriert werden, wohingegen die Substitution 100 C-terminaler Aminosäuren zum Funktionsverlust des Proteins führt.

We reinvestigated major steps in the replicative cycle of pseudorabies virus (PrV) by electron microscopy of infected cultured cells. Virions attached to the cell surface were found in two distinct stages, with a distance of 12 to 14 nm or 6 to 8 nm between virion envelope and cell surface, respectively. After fusion of virion envelope and cell membrane, immunogold labeling using a monoclonal antibody against the envelope glycoprotein gE demonstrated a rapid drift of gE from the fusion site, indicating significant lateral movement of viral glycoproteins during or immediately after the fusion event. Naked nucleocapsids in the cytoplasm frequently appeared close to microtubules prior to transport to nuclear pores. At the nuclear pore, nucleocapsids invariably were oriented with one vertex pointing to the central granulum at a distance of about 40 nm and viral DNA appeared to be released via the vertex region into the nucleoplasm. Intranuclear maturation followed the typical herpesvirus ...

Although pseudorabies virus can affect a wide range of mammalian and avian hosts, swine are the only natural hosts of the virus. The US commercial swine industry obtained pseudorabies-free status in 2004, which was important because of the economic value of domestic swine production; however, feral swine remain competent hosts and represent a constant threat for reintroducing the virus into the commercial industry. To better assess feral swine infection status, we collected 8,498 serum samples from feral swine across the United States between 1 October 2009 and 30 September 2012. Of these, 18% were antibody positive in 25 of 35 states where samples were collected, indicating that transmission risk is widespread.

PURDUE J , vererinory medical VOLUME 3, NUMBER 2 SUMMER-FALL 1977 PSEUDORABIES TEST Considerable attention is being given to determining whether or not a given group of swine, or individual pigs, have reacted to a presumed exposure to pseudorabies virus (PrV) and diagnostic laboratories are receiving an increasingly large number of serum specimens for evaluation. There is a need for an on-the-farm method to enable practicing veterinarians to determine the immune status of a swine herd. We have been developing and field testing antigens which can be used to elicit a local skin allergic reaction in swine that have recovered from PrV infection. This is based on an observation reported in 1967 by workers in Eastern Europe. Thus far three antigens have been tested and two additional methods of antigen production/inactivation are to be studied. An antigen inactivated by 60co irradiation has been found to be successful but slightly less sensitive than the serum neutralization (SN) test that is used in ...

In most viral infections, the immune system has the opportunity to counteract the virus particle, at certain times of infection (prior to entering the cell or leave it, after replication), and the infected cells (during production of viral proteins or the assembly), since they appear in the infection of the membrane antigens that trigger the immune response. In some cases, such as pig endogenous retroviruses (have been described three types: A, B, B1 and C), or in the herpes virus (Aujeszkys disease), the infection can circulate for long periods of time without giving you a virus particle, or that infected cells express membrane antigens. In these moments, the mechanisms of the system immunity are ineffective, because the enemy does not offer any kind of signal, but at a given time (not familiar with all the circumstances) infection and reactive free new infectious virions ...

The experiment was conducted to evaluate the effects of dietary threonine (Thr) supplement on reproductive performance and immune function of the male mice challenged with pseudorabies virus (PRV). Kun-Ming male mice were assigned randomly to four groups with different Thr levels (0.70%, 0.88%, 1.10% and 1.30%). Half of the mice in each group were injected with PRV or phosphate-buffered saline (PBS) after 5 weeks adaptation to diets. The second experiment examined the effects of dietary Thr level on copulation rate, pregnancy rate and average number per litter of PRV- or PBS-challenged male mice that copulated with adult female mice on the 9th day post PRV challenge. Sperm quality and testosterone of mice were decreased after PRV infection, but this effect was attenuated by increasing Thr levels. Copulation and conception rates were increased with increasing Thr levels (P = 0.14), but litter size was not affected (P > 0.05). In the PBS and PRV groups, mice fed higher levels of Thr had increased ...

Nectin-1 is an alphaherpesvirus receptor that binds to virion glycoprotein D by the first immunoglobulin (Ig)-like domain. The possibility of making animals resistant to pseudorabies virus (PRV) infection has been investigated by generating transgenic mice expressing soluble forms of porcine nectin-1. Previously, transgenic mice were generated that expressed a fusion protein made of the entire ectodomain of nectin-1 fused to the Fc portion of human IgG, or the first Ig-like domain fused to the Fc portion of porcine IgG. Here, the contribution of the second and third Ig-like domains of nectin-1 was analysed by generating transgenic mice expressing the entire ectodomain of nectin-1 fused to the porcine Fc portion. Transgenic mice expressing each of three different fusion proteins were challenged with PRV for comparison of their resistance. Altogether, mice transgenic for a chimera that carried the entire ectodomain were more resistant than those transgenic for a chimera that carried the first Ig-like

During her postdoctoral work at Princeton, Szpara introduced the use of high-throughput DNA sequencing to her field -- producing the first new HSV genome sequences in two decades. That provided the raw material for the first genome-wide comparative analysis of alpha-herpesviruses (the class of herpesviruses that includes HSV-1 and HSV-2), yielding valuable insights into the diversity of herpesvirus genetic sequences and protein coding ability. Building on this work, Szpara applied the same approaches to studying a related animal herpesvirus, pseudorabies virus (PRV), and discovered several key genomic characteristics contributing to virulence and mutability in PRV. Multiple vaccine strains of PRV, including one recently sequenced by Szpara, serve as a model for HSV vaccine development.. At the same time, Szpara pursued the question of how neurons respond to pathogen infection. In mouse models of HSV-1 and PRV infection, Szpara measured genome-wide transcriptional responses (transcription being ...

Alpha herpesvirus genomes encode the capacity to establish quiescent infections (i.e. latency) in the peripheral nervous system for the life of their hosts. Multiple times during latency, viral genomes can reactivate to start a productive infection, enabling spread of progeny virions to other hosts. Replication of alpha herpesviruses is well studied in cultured cells and many aspects of productive replication have been identified. However, many questions remain concerning how a productive or a quiescent infection is established. While infections in vivo often result in latency, infections of dissociated neuronal cultures in vitro result in a productive infection unless lytic viral replication is suppressed by DNA polymerase inhibitors or interferon. Using primary peripheral nervous system neurons cultured in modified Campenot tri-chambers, we previously reported that reactivateable, quiescent infections by pseudorabies virus (PRV) can be established in the absence of any inhibitor. Such ...

MicroRNAs are small non-coding RNAs approximately 22 nt long that modulate gene expression in animals and plants. It has been recently demonstrated that herpesviruses encode miRNAs to control the post-transcriptional regulation of expression from their own genomes and possibly that of their host, thus adding an additional layer of complexity to the physiological cross-talk between host and pathogen. The present study focussed on the interactions between porcine dendritic cells (DCs) and the Pseudorabies virus (PRV), an alpha-herpesvirus causing Aujeszkys disease in pigs. A catalogue of porcine and viral miRNAs, expressed eight hours post-infection, was established by deep sequencing. An average of 2 million reads per sample with a size of 21-24 nucleotides was obtained from six libraries representing three biological replicates of infected and mock-infected DCs. Almost 95% of reads mapped to the draft pig genome sequence and pig miRNAs previously annotated in dedicated databases were detected ...

Different alphaherpesviruses, including pseudorabies virus (PRV), are able to cross the basement membrane barrier in nasal respiratory epithelium. As a first step in investigating this invasion process, a detailed quantitative analysis system was set up to determine the kinetics of horizontal and vertical virus spread in nasal explants, using the virulent PRV strain 89V87. Plaque latitudes, total depths, depths measured from the basement membrame and volumes were determined at 0, 12, 24 and 36 h post inoculation (pi). PRV 89V87 was found to spread in a plaquewise manner and to cross the basement membrane between 12 and 24 hpi. During the 1960s-1970s, an increase in PRV virulence has been reported. To analyse potential differences in efficiency of infection and spread for different historical PRV strains, single infected cells and plaques of infected cells were quantified at 12 and 36 hpi in nasal mucosa explants for seven European PRV strains, isolated in the 1960s (Becker, NIA1), the 1970s ...

This study evaluated vaccinia-vectored vaccines expressing glycoproteins gB, gC, or gD of pseudorabies virus (PRV) in pigs. The vaccines are based on an attenuated vaccinia virus strain, NYVAC, which has reduced virulence and replicative capacity for certain species, including swine. The recombinant vaccinia vaccines were unable to prevent replication of virulent pseudorabies virus or latency but they were able to decrease the amount of virus shed after challenge and decrease clinical signs. In particular, pigs vaccinated with the recombinants expressing either gB or gD were protected at a level comparable to an inactivated PRV virus that was given for comparison. No lesions or clinical signs were seen following vaccination in these studies and no seronegative pigs in contact with vaccinia-vaccinated pigs ever seroconverted. No significant increase in protection occurred by giving recombinants expressing multiple glycoproteins and there was no virus neutralizing antibody response or protection induced

Glycoprotein B of PrV is essential for infection of target cells by free virions and for direct viral cell-to-cell spread. In this report, the function in these processes of different domains within the cytoplasmic tail of PrV gB was analyzed. To this end, mutated gB proteins were expressed and characterized.. While wild-type gB was mainly observed in intracellular accumulations and not at the plasma membrane, all gB derivatives containing truncations of at least the carboxy-terminal 29 aa of the cytoplasmic tail localized to the plasma membrane. This was true for gB expressed during virus infection as well as gB expressed without other viral proteins in stably transformed cell lines. Thus, within the last 29 aa of PrV gB, a signal appears to be located which precludes accumulation of gB in the plasma membrane. Within this region of gB, a dileucine motif and a YQRL motif, both potential signals for internalization (24, 25), are present. A similar YQRL endocytosis motif has been found in gB of ...

The Canadian Food Inspection Agency (CFIA) has enhanced its surveillance activities for porcine brucellosis, trichinellosis, and pseudorabies (Aujeszkys disease).

Fourteen of 16 feral hogs seized by Colorado state wildlife and agriculture officials have been diagnosed with pseudorabies (PRV).

The histology of pseudorabies differs materially in various animal species. In the rabbit, subcutaneous, intradermal or intramuscular inoculation leads to local inflammation and necrosis. The infection ascends the peripheral nerve (possibly both interstitially and by the axis-cylinders) to the corresponding spinal ganglia and segments of the spinal cord, where primary degeneration of nerve and glial cells takes place. The nerve cell changes are probably responsible for the cardinal symptom of the disease, itching. Death ensues soon after virus reaches the medulla, before visible changes have been produced here. Intracerebral inoculation is followed by characteristic lesions in the meninges, in subpial glial cells and in superficially placed nerve cells. Morbid changes in the lungs are not necessarily related to the presence of virus, but specific lesions may be present. Intranuclear inclusions bearing some resemblance to those in herpetic encephalitis, yellow fever, etc., occur in cells derived ...

Herpesviren nutzen einen Vesikel-vermittelten Transportweg für die Translokation von Nukleokapsiden aus dem Zellkern, um für die weitere Virusmorphogenese in das Zytoplasma zu gelangen. Den dafür notwendigen Kernfreisetzungskomplex (nuclear egress complex; NEC) bilden zwei konservierte herpesvirale Proteine, die als pUL34 und pUL31 bezeichnet werden. Die Kristallstrukturen der NECs aus verschiedenen Herpesviren zeigten eine stabile Interaktion zwischen der N-terminalen Domäne von pUL31 und dem Kern von pUL34.

The annual Pork Congress wraps up today, and a workshop on herd health will be one of many offered to visiting farmers at Vets Auditorium in Des Moines. State Veterinarian Dr. Patrick Webb put together the presentation, and he says Iowas taken an aggressive approach to keeping its hog herds healthy. The states now nearly free of the pig disease pseudorabies, and Dr. Webb says thats taken a lot of work. The state vet says the health of Iowas animals is very high, but farmers and state officials need to keep making plans to handle any contingencies. Webb says in the case of pseudorabies, there are no known infected herds right now, and Iowa can hope to achieve free status within a year or two. Eventually, pseudorabies could become a foreign animal disease, as itll be completely wiped out in this country.. ...

The pathophysiology of IC is complex and not completely understood. This makes it difficult to develop definitive therapeutic modalities and to establish a standard animal model for translational research. Current approaches have mostly emphasized merging clinical practice and translational research; therefore, it is important to establish proper translational models similar to the disease in humans. Approximately 20 animal models with some similar characteristics to the IC phenotype have been generated over the past several decades [15,18]. From 1980 to 2000, the models were typically prepared by inducing inflammatory conditions in the bladder by intravesical instillation of chemical irritants, such as acetone, acrolein, acid, turpentine, mustard oil, or croton oil [19-22]. In the 2000s, IC animal models were commonly generated by injection of bacterial LPS, systemic administration of CYP, pseudorabies virus infection, or systemic induction of autoimmunity [9,14,16,23,24]. Although these ...

Author summary It is assumed that Pteropine orthoreovirus (PRV) is a causative agent of acute respiratory tract infection (RTI) in humans. PRV was isolated from patients and fruit bats in Southeast Asia. Furthermore, the genome of PRV was detected in patients with respiratory symptoms, suggesting that PRV causes RTI in humans. There is a potential for PRV to cause RTIs in tropical or sub-tropical regions in Southeast Asia more widely than thought. The virulence, pathology, and pathogenesis of PRV in BALB/c mice were elucidated in detail. To develop specific countermeasures and prophylactics against PRV infection, an animal model of lethal PRV infection is needed, and we developed such a model using BALB/c mice. This model allows investigation of the pathogenicity of PRV and evaluation of the efficacy of drugs and vaccines and might help to accelerate research on the virology of PRV.

In the study, the researchers investigated a known factor for SUDS: maternal smoking during pregnancy. They analyzed the Centers for Disease Control and Prevention Birth Cohort Linked Birth / Infant Death Data from 2007. The results showed that SUID risk more than doubled with any maternal smoking during pregnancy, and increased twofold between no smoking and smoking 1 cigarette daily through pregnancy. For 1-20 cigarettes per day, the probability of SUID increased linearly, with each additional cigarette smoked per day increasing the odds of SUID by 0.07. Beyond 20 cigarettes per day, the relationship between SUID plateaued.. Mothers who quit or reduced their smoking during pregnancy decreased their odds of the baby experiencing SUID (as compared with mothers who continued smoking during pregnancy). The researchers concluded that the data supports a need for smoking cessation before pregnancy. If no women in the United States smoked in pregnancy, the rates of SUIDs in the United States could be ...

During infection of neurons by alphaherpesviruses including Pseudorabies virus (PRV) and Herpes simplex virus type 1 (HSV-1) viral nucleocapsids assemble in the cell nucleus, become enveloped in the cell body then traffic into and down axons to nerve termini for spread to adjacent epithelia. The viral membrane protein US9p and the membrane glycoprotein heterodimer gE/gI play critical roles in anterograde spread of both HSV-1 and PRV, and several models exist to explain their function. Biochemical studies suggest that PRV US9p associates with the kinesin-3 motor KIF1A in a gE/gI-stimulated manner, and the gE/gI-US9p complex has been proposed to recruit KIF1A to PRV for microtubule-mediated anterograde trafficking into or along the axon. However, as loss of gE/gI-US9p essentially abolishes delivery of alphaherpesviruses to the axon it is difficult to determine the microtubule-dependent trafficking properties and motor-composition of Δ(gE/gI-US9p) particles. Alternatively, studies in HSV-1 have ...

Antibodies in porcine sera against glycoprotein E (gE) of pseudorabies virus (PRV) are usually measured in blocking enzyme-linked immunosorbent assays (ELISAs) with one or two murine monoclonal antibodies (MAbs) directed against gE. Our aim was to develop a confirmation assay which is based on another principle and which is able to detect antibodies directed against most potential binding sites on gE with high specificity. Therefore, we developed an indirect double-antibody sandwich assay (IDAS) using recombinant gE expressed by baculovirus (BacgE960). A fragment of the gE gene consisting of nucleotide positions +60 to +1020 of gE, coding for the major antigenic sites of gE but not the transmembrane region, was cloned behind the signal sequence of PRV gG and the p10 promoter in a baculovirus vector. Immunoblot analysis showed that the expressed protein reacted with MAbs directed against five of the six antigenic sites on gE. Although the conformation of some antigenic sites, notably antigenic ...

Yesterdays Chicago Tribune reports that for the first time in Wisconsin, an Amish farmer has been charged civilly with failing to comply with the states livestock premise registration law. The law is designed to facilitate notice to farmers when there are emergencies or disease outbreaks. Emanuel Miller, Jr.s failure to register slowed down the states response to a 2007 outbreak of pseudorabies. The Amish are concerned that the identification number that will be assigned to their farm could be considered the mark of the beast. Miller faces a possible fine of up to $5000 ...
