Borna disease virus
A species in the genus Bornavirus, family BORNAVIRIDAE, causing a rare and usually fatal encephalitic disease in horses and other domestic animals and possibly deer. Its name derives from the city in Saxony where the condition was first described in 1894, but the disease occurs in Europe, N. Africa, and the Near East.
Infectious bursal disease virus
Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions.
A dilated cavity extended caudally from the hindgut. In adult birds, reptiles, amphibians, and many fishes but few mammals, cloaca is a common chamber into which the digestive, urinary and reproductive tracts discharge their contents. In most mammals, cloaca gives rise to LARGE INTESTINE; URINARY BLADDER; and GENITALIA.

Viral Plaque Assay
Method for measuring viral infectivity and multiplication in CULTURED CELLS. Clear lysed areas or plaques develop as the VIRAL PARTICLES are released from the infected cells during incubation. With some VIRUSES, the cells are killed by a cytopathic effect; with others, the infected cells are not killed but can be detected by their hemadsorptive ability. Sometimes the plaque cells contain VIRAL ANTIGENS which can be measured by IMMUNOFLUORESCENCE.

L Cells (Cell Line)
Methods of maintaining or growing biological materials in controlled laboratory conditions. These include the cultures of CELLS; TISSUES; organs; or embryo in vitro. Both animal and plant tissues may be cultured by a variety of methods. Cultures may derive from normal or abnormal tissues, and consist of a single cell type or mixed cell types.
The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).
Hemagglutination Inhibition Tests
Tumor-selective, replication competent VIRUSES that have antineoplastic effects. This is achieved by producing cytotoxicity-enhancing proteins and/or eliciting an antitumor immune response. They are genetically engineered so that they can replicate in CANCER cells but not in normal cells, and are used in ONCOLYTIC VIROTHERAPY.

Border disease virus
Influenza A Virus, H5N1 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 5 and neuraminidase 1. The H5N1 subtype, frequently referred to as the bird flu virus, is endemic in wild birds and very contagious among both domestic (POULTRY) and wild birds. It does not usually infect humans, but some cases have been reported.
Viral Structural Proteins
Viral proteins that are components of the mature assembled VIRUS PARTICLES. They may include nucleocapsid core proteins (gag proteins), enzymes packaged within the virus particle (pol proteins), and membrane components (env proteins). These do not include the proteins encoded in the VIRAL GENOME that are produced in infected cells but which are not packaged in the mature virus particle,i.e. the so called non-structural proteins (VIRAL NONSTRUCTURAL PROTEINS).
Aleutian Mink Disease Virus
Sequence Analysis, DNA
Multinucleated masses produced by the fusion of many cells; often associated with viral infections. In AIDS, they are induced when the envelope glycoprotein of the HIV virus binds to the CD4 antigen of uninfected neighboring T4 cells. The resulting syncytium leads to cell death and thus may account for the cytopathic effect of the virus.

Amino acid substitutions in a conserved region in the stalk of the Newcastle disease virus HN glycoprotein spike impair its neuraminidase activity in the globular domain. (1/926)The ectodomain of the paramyxovirus haemagglutinin-neuraminidase (HN) glycoprotein spike can be divided into two regions: a membrane-proximal, stalk-like structure and a terminal globular domain. The latter contains all the antibody recognition sites of the protein, as well as its receptor recognition and neuraminidase (NA) active sites. These two activities of the protein can be separated by monoclonal antibody functional inhibition studies and mutations in the globular domain. Herein, we show that mutation of several conserved residues in the stalk of the Newcastle disease virus HN protein markedly decrease its NA activity without a significant effect on receptor recognition. Thus, mutations in the stalk, distant from the NA active site in the globular domain, can also separate attachment and NA. These results add to an increasing body of evidence that the NA activity of this protein is dependent on an intact stalk structure. (+info)
Pathogenesis of Newcastle disease in chickens experimentally infected with viruses of different virulence. (2/926)Groups of 4-week-old White Rock chickens were inoculated intraconjunctivally with nine isolates of Newcastle disease virus representing all pathotypes. Birds were monitored clinically and euthanatized sequentially, with collection of tissues for histopathologic examination and in situ hybridization using an anti-sense digoxigenin-labeled riboprobe corresponding to the sequence of the gene coding for the matrix protein. Disease was most severe with velogenic viscerotropic pathotypes and was characterized by acute systemic illness with extensive necrosis of lymphoid areas in the spleen and intestine. Viral nucleic acid was detected in multiple tissues but most prominently in macrophages associated with lymphoid tissue. Velogenic neurotropic isolates caused central nervous system disease despite minimal amounts of viral nucleic acid detected in neural tissue. Mesogenic and lentogenic pathotypes caused no overt disease; however, viral nucleic acid was present in myocardium and air sac epithelium following infection with these isolates. Compromise of air sac and myocardium may predispose mesogen- and lentogen-infected chickens to secondary infection and/or decreased meat and egg production. (+info)
Isolation and characterization of monoclonal antibodies directed against murine FRP-1/CD98/4F2 heavy chain: murine FRP-1 is an alloantigen and amino acid change at 129 (P<-->R) is related to the alloantigenicity. (3/926)Nineteen mAb directed against murine fusion regulatory protein-1 (mFRP-1)/4F2/CD98 were isolated and their biological properties were analysed. Intriguingly, mFRP-1 was found to be an alloantigen, namely, FRP-1.1 (DBA/2 and CBA mice type) and FRP-1.2 (BALB/c, C57BL/6 and C3H/He mice type). The nucleotide sequences of FRP-1.1 and FRP-1.2 were determined, demonstrating that amino acid change at 129 (P<-->R) is related to the alloantigenicity. mFRP-1 is expressed on thymocytes, on spleen cells, on peripheral lymphocytes and on blood monocytes, suggesting that the physiological role in vivo of murine FRP-1 is different from that of human FRP-1. The biological activities of antimFRP-1 mAbs showed by the present study are: (i) enhancement of Newcastle disease virus-induced cell fusion; (ii) suppression of HIVgp160-mediated cell fusion; and (iii) induction of aggregation and multinucleated giant cells of monocytes/macrophages.

Mutational analysis of heptad repeats in the membrane-proximal region of Newcastle disease virus HN protein. (4/926)For most paramyxoviruses, syncytium formation requires the expression of both surface glycoproteins (HN and F) in the same cell, and evidence suggests that fusion involves a specific interaction between the HN and F proteins (X. Hu et al., J. Virol. 66:1528-1534, 1992). The stalk region of the Newcastle disease virus (NDV) HN protein has been implicated in both fusion promotion and virus specificity of that activity. The NDV F protein contains two heptad repeat motifs which have been shown by site-directed mutagenesis to be critical for fusion (R. Buckland et al., J. Gen. Virol. 73:1703-1707, 1992; T. Sergel-Germano et al., J. Virol. 68:7654-7658, 1994; J. Reitter et al., J. Virol. 69:5995-6004, 1995). Heptad repeat motifs mediate protein-protein interactions by enabling the formation of coiled coils. Upon analysis of the stalk region of the NDV HN protein, we identified two heptad repeats. Secondary structure analysis of these repeats suggested the potential for these regions to form alpha helices. To investigate the importance of this sequence motif for fusion promotion, we mutated the hydrophobic a-position amino acids of each heptad repeat to alanine or methionine. In addition, hydrophobic amino acids in other positions were also changed to alanine. Every mutant protein retained levels of attachment activity that was greater than or equal to the wild-type protein activity and bound to conformation-specific monoclonal as well as polyclonal antisera. Neuraminidase activity was variably affected. Every mutation, however, showed a dramatic decrease in fusion promotion activity. The phenotypes of these mutant proteins indicate that individual amino acids within the heptad repeat region of the stalk domain of the HN protein are important for the fusion promotion activity of the protein. These data are consistent with the idea that the HN protein associates with the F protein via specific interactions between the heptad repeat regions of both proteins. (+info)
Rescue of Newcastle disease virus from cloned cDNA: evidence that cleavability of the fusion protein is a major determinant for virulence. (5/926)A full-length cDNA clone of Newcastle disease virus (NDV) vaccine strain LaSota was assembled from subgenomic overlapping cDNA fragments and cloned in a transcription plasmid between the T7 RNA polymerase promoter and the autocatalytic hepatitis delta virus ribozyme. Transfection of this plasmid into cells that were infected with a recombinant fowlpoxvirus that expressed T7 RNA polymerase, resulted in the synthesis of antigenomic NDV RNA. This RNA was replicated and transcribed by the viral NP, P, and L proteins, which were expressed from cotransfected plasmids. After inoculation of the transfection supernatant into embryonated specific-pathogen-free eggs, infectious virus derived from the cloned cDNA was recovered. By introducing three nucleotide changes in the cDNA, we generated a genetically tagged derivative of the LaSota strain in which the amino acid sequence of the protease cleavage site (GGRQGR downward arrowL) of the fusion protein F0 was changed to the consensus cleavage site of virulent NDV strains (GRRQRR downward arrowF). Pathogenicity tests in day-old chickens showed that the strain derived from the unmodified cDNA was completely nonvirulent (intracerebral pathogenicity index [ICPI] = 0.00). However, the strain derived from the cDNA in which the protease cleavage site was modified showed a dramatic increase in virulence (ICPI = 1.28 out of a possible maximum of 2.0). Pulse-chase labeling of cells infected with the different strains followed by radioimmunoprecipitation of the F protein showed that the efficiency of cleavage of the F0 protein was greatly enhanced by the amino acid replacements. These results demonstrate that genetically modified NDV can be recovered from cloned cDNA and confirm the supposition that cleavage of the F0 protein is a key determinant in virulence of NDV. (+info)
Local immunity in the respiratory tract of the chicken. I. Transudation of circulating antibody in normal and virus-infected birds. (6/926)Three-week-old chickens were given sheep erythrocytes or bovine serum albumin intravenously. Seven days later their tears and saliva possessed low levels of antibody to those antigens. Concurrent infection with lentogenic Newcastle disease virus (NDV) caused a significant increase in transuded antibody in those fluids. In chickens with circulating antibody to NDV, induced by parenterally administered inactivated vaccine, respiratory infection with heterologous infectious bronchitis virus resulted in limited transudation of anti-NDV. In contrast, the tears, saliva and tracheal fluid of non-vaccinated chickens undergoing primary infection with NDV acquired considerable levels of specific anti-NDV. The difference between the two groups is attributed to locally synthesized antibody. (+info)
Purification of two components of mouse L cell interferon: electrophoretic demonstration of interferon proteins. (7/926)Mouse L cell interferon induced by Newcastle disease virus was purified by the procedure described previously (Yamamoto et al. 1974) followed by gel filtration. The two fractions obtained containing interferon species S (36000 daltons) and F (24000 daltons), respectively, were analysed electrophoretically at pH 4-3, or in the presence of sodium dodecyl sulphate (SDS) at pH 7-2. In both fractions, interferon activity was invariably associated with distinct protein bands. In the F-containing fraction there were essentially no other proteins, and in the S-containing fraction, impurity proteins were well separated from the interferon activity. The apparent mol. wt. determined by SDS-gel electrophoresis showed little or no dependence on gel concentration, suggesting that the interferons had low carbohydrate contents, and did not change after reduction with thiol reagents in SDS and urea.

The production and action of interferon in Chinese hamster cells. (8/926)The interferon system has been investigated in primary cell cultures established from Chinese hamster embryos and new born pups. Interferon synthesis was induced with Sindbis virus, ultraviolet inrradiated Newcastle disease virus (u.v.-NDV) and with polyriboinosine acid-polyribocytidylic acid complex [poly (rI). poly (rC)]. Only u.v.-NDV induced significant production of interferon, maximum amounts being produced in 'aged' cells. Its apparent mol. wt. was 25000. CHO-KI cells, an established line of Chinese hamster cells, did not synthesize interferon in response to viruses, but were sensitive to its action. (+info)
Construction of recombinant Newcastle disease virus Italien strain for oncolytic virotherapy of tumors
Newcastle disease virus (NDV) is a naturally oncolytic virus that has been shown to be safe and effective for cancer therapy. Tumor virotherapy using NDV emerged in the 1950s and has advanced more recently by the increased availability of reverse genetics technology. In this study, we constructed a reverse genetics system based on the virulent and oncolytic NDV Italien strain, and generated two recombinant NDVs carrying a gene encoding either enhanced green fluorescent protein or firefly luciferase. We evaluated the replication and antitumor characteristics of these viruses in vitro and in vivo. Our data showed that the insertion of exogenous reporter genes did not affect NDV replication and sensitivity to type I interferon. The recombinant NDVs kept the property of tumor-selective replication both in vitro and in vivo and strongly induced syncytium formation leading to cell death. Moreover, the recombinant NDVs significantly prolonged the survival of tumor-bearing athymic mice (p=0.017) and ...
Molecular characterisation of Newcastle disease virus isolates from different geographical regions in Mozambique in 2005 -...
Newcastle disease (ND) is regarded as a highly contagious and economically important disease in poultry and has a worldwide distribution. Viral determinants for Newcastle disease virus (NDV) virulence are not completely understood and viruses of different pathotypes can be found at live-bird markets in different geographical areas. The prevalence of Newcastle disease in village poultry in Mozambique is not well documented and strains of NDV involved in yearly outbreaks are unknown. The fusion (F) protein is an important determinant of pathogenicity of the virus and is used commonly for phylogenetic analysis. Newcastle disease viruses from various geographical regions of Mozambique were sequenced and compared genetically to published sequences obtained from GenBank. Samples were collected in three different areas of Mozambique and NDV was isolated by infection of embryonated chicken eggs. Sequence analysis of the F-protein encoding gene was used to classify 28 isolates from Mozambique into ...
Cloned vaccines against Newcastle disease virus, heterologous protection against genotypes VII a XII | The Poultry Site
The appearance of very aggressive outbreaks of Newcastle disease is caused by velogenic strains with genotypes different from those present in the classic vaccines currently being used, resulting in doubts about the efficacy of classical live attenuated vaccines. Newcastle disease (ND) is caused by virulent forms of avian Paramyxovirus serotype 1 (APMV-1). Newcastle Disease virus (NDV) is classified into different classes and genotypes based on its genetic characteristics. Epidemiological control of Newcastle disease in broilers is possible (amongst other tools) thanks to the intensive use of prophylactic vaccination. In general, the most common vaccines in the world against this disease are based on two main genotypes of live lentogenic NDV (genotype I and II), characterised by low pathogenicity or apathogenicity. The genetic divergence between the genotypes of the vaccines and the circulating viruses raises questions about their efficacy.. An independent study by Jeon et al. demonstrated the ...

Passive immunity in chicks from a laying flock vaccinated with the Mukteswar strain of Newcastle disease virus - UQ eSpace
Pullets about to enter a laying flock were revaccinated by intramuscular injection of live Mukteswar strain Newcastle disease virus, a procedure commonly used in Pakistan. Chicks hatched from eggs produced 24 weeks later were assessed for passively acquired immunity. Levels of haemagglutination-inhibition (HI) antibody and resistance to challenge with velogenic Newcastle disease virus were determined on groups of 50 chicks at 1, 4, 7, 10, 13, 16, 19, 22 and 25 days of age. Levels of maternally derived antibody declined from a geometric mean titre of 40 (25.3) on the day of hatching to less than two (20.3) at 25 days of age, with a decline of 1log2 in about 5 days. Mortalities after challenge varied from 18% at 1 day of age to 90% at 25 days of age. Survival was significantly related to the level of antibody at the time of challenge. None of 111 chickens with an antibody titre of 40 (25.3) or more succumbed to challenge. Mortality rates varied from 78.6% in chicks with no detectable antibody at ...
Site-specific glycosylation of the Newcastle disease virus haemagglutinin-neuraminidase - UQ eSpace
Members of the Avulavirus, Respirovirus and Rubulavirus genera of the Paramyxoviridae family of viruses utilise haemagglutinin-neuraminidase glycoproteins as their attachment proteins. These glycoproteins are oligomeric type II integral membrane proteins, which possess haemagglutination and sialidase activity. Previous studies have shown that the N-linked glycans present on these proteins can modulate the ability of the virus to infect host cells and stimulate the host immune system. However, site-specific heterogeneity of these glycans has not been defined. This study concerns characterisation of the glycan compositions attached to haemagglutinin-neuraminidase of the Avulavirus Newcastle disease virus, which causes Newcastle disease in a range of avian species. Haemagglutinin-neuraminidase was derived from egg propagated virions of V4-VAR, an isolate of the avirulent strain QLD/66. Reverse-phase liquid chromatography tandem mass spectrometry strategies including collision induced dissociation, ...
Biological and genotypic characterization of the Newcastle disease virus isolated from disease outbreaks in commercial poultry...
Newcastle disease (ND) is a highly contagious disease of many avian species and is particularly responsible for devastating disease outbreaks in commercial poultry flocks in Pakistan that incur huge economic losses to the national poultry industry annually. Despite implementation of an extensive vaccination program for poultry birds, the disease appears in an endemic form in commercial broiler and layer poultry farms. This study was conducted to identify the prevalent velogenic NDV strain responsible for disease outbreaks in commercial poultry farms in Punjab, Pakistan. The NDV strains isolated from pathological specimens through inoculation in embryonated chicken eggs were characterized biologically through the intracerebral pathogenicity index (ICPI), and genetically on the basis of the fusion (F) protein cleavage site. Among these, six NDV isolates showed an F protein cleavage site motif (112RRQKRF117) and an ICPI value ranging between 1.5 and 1.88, both are characteristics for velogenic ...

Newcastle Disease Virus Vaccine on the Horizon | The Poultry Site
Newcastle disease virus (NDV) is an important pathogen that causes disease and death not only in domestic and commercial poultry, but also in wild bird populations around the world. Current Newcastle disease (ND) vaccines are used widely in commercial poultry and protect the vaccinated birds from disease but do not prevent them from becoming infected and carrying the virulent virus or shedding it in their faeces. Therefore, the current vaccines do not eliminate virulent virus transmission from infected to healthy birds ...
Circulation of Recently Reported Sub-genotype VII1.1 of Newcastle Disease Virus in Commercial and Backyard Chicken in north of...
BACKGROUND: Newcastle disease virus (NDV) majorly infects the poultry, and despite high rates of vaccination, it is still circulating in different geographical regions. Due to the high mortality rate, the economic loss of Newcastle disease (ND) is enormous. OBJECTIVES: The molecular characterization of NDV isolates from chicken farms in Northern Iran, during 2017-2018, was the main goal of this study. METHODS: We isolated and characterized five NDVs from commercial broiler and backyard chicken farms during severe disease outbreak. The partial coding sequence of fusion (F) genes of isolates was determined and compared with those of other published NDVs. RESULTS: Phylogenetic analysis revealed that all of the isolates were grouped into sub-genotype VII.1.1 (formerly known as VIIl). All isolates carried multi‐basic amino acid residues at the cleavage site of fusion protein, typical of virulent strains. Studied NDV isolates had high homology with the prevalent genotype NDV strains that currently

Despite routine vaccination programs against Newcastle disease (ND), sporadic cases have occasionally occurred that remain a constant threat to commercial poultry. Egypt is endemic for Newcastle disease virus (NDV) with continuous long-lasting outbreaks causing significant losses in the poultry industry since 1948. This study was designed to identify various NDVs associated with outbreaks occurred in different localities in Egypt (El-Behera and Beni-Swief governorates) from March 2014 to November 2014among chicken flocks by RT-PCRand estimate its virulence in chickens byintra-cerebral pathogenicity index (ICPI). Thirty seven samples were collected from chickens either alive or dead showing characteristic clinical findings and post-mortem lesions of NDV. Virus propagation in embryonated chicken eggs was confirmed by hemagglutination (HA) test and identified by hemagglutination inhibition (HI) test using NDV specific antiserum. The results indicated that 16 (43.2 %) out of 37 samples were NDV ...
Plaque formation of LaSota pathogenic strain of Newcastle disease virus adapted in chick embryo fibroblast cells
In order to adapt LaSota strain of Newcastle disease virus (NDV) on chick embryo fibroblast (CEF) cells, 0.1 ml from LaSota vaccine produced in Razi vaccine and serum research institute inoculated to the CEF cells and was passaged five times in the CEF grown in Eagles minimum essential medium (MEM). First to third passages were blind but in fourth passage cytopathic effect of virus was observed. Fifth passage viruses were propagated in SPF embryoneted eggs and then harvested allantoic fluids showed presence of NDV with the titer of 108 EID50/ml. Plaque assays performed on this harvest using two agar overlays one supplemented with trypsin, DEAE dextran and magnesium sulfate, the second with neutral red along with the mentioned supplements, overlaid 72 hours after first one. Eight hours later, plaques of adapted virus appeared with various sizes ranging from 1 mm to 3 mm in the diameter. Discrete plaques were observed in the 10-6 dilution and the calculated titer of virus was 3×107 pfu/ml. Agar medium
Poultry disease: Why vaccination against the Newcastle disease has low success
One of the major challenges facing the poultry industry is controlling disease outbreaks. The birds are routinely pumped with antibiotics and vaccines. However, vaccines do not always ensure that the diseases are kept at bay. One such disease that can affect the birds despite regular vaccination against it is the Newcastle disease. It is named after the populous city in North Eastern England where it was first identified. It is a fatal disease caused by a virus that goes by the same name, the Newcastle disease virus. This disease is reported from across the globe and is caused by 18 known variants, numbered from I to XVIII, of the Newcastle disease virus (NDV). Some variants are highly virulent, causing severe, often fatal infection and some cause mild symptoms. ...

Location of Post-translational Cleavage Events Within F and HN Glycoproteins of Newcastle Disease Virus | Microbiology Society
Summary The biologically active form of the fusion glycoprotein F from Newcastle disease virus (NDV) comprises two polypeptides, F1 and F2 (derived from a precursor polypeptide F0 by a post translational cleavage event), which are covalently linked together (F1,2) by disulphide bonds. This feature was exploited in a two-dimensional SDS-polyacrylamide gel electrophoretic analysis to orientate the position of the cleavage event within F0. Separation of proteins from NDV-infected CEF in the first dimension in the absence of reducing agent resolved F1,2 protein from all NDV-induced proteins other than F0. Reduction of the first dimension gel with 2-mercaptoethanol, followed by electrophoresis in the second dimension, resolved F1 (55K), F2 (12.5K) and F0 (64K) proteins. The only polypeptides other than F1 and F2 which fell below the diagonal, indicating the positions of the polypeptides from infected cells, were two minor glycoproteins designated HN1 (51.5K) and HN2 (27.5K) which took up positions vertically

Frontiers | Roles of the polymerase-associated protein genes in Newcastle disease virus virulence | Microbiology
The virulence of Newcastle disease virus varies greatly and is determined by multiple genetic factors. In this study, we systematically evaluated the roles of the polymerase-associated (NP, P and L) protein genes in genotype VII NDV virulence after confirming the envelope-associated (F and HN) proteins contributed greatly to NDV virulence. The results revealed that the polymerase-associated protein genes individually had certain effect on virulence, while transfer of these three genes in combination significantly affected the chimeric virus virulence, especially when the L gene was involved. These results indicated that the L protein was a major contributor to NDV virulence when combined with the homologous NP and P proteins. We also investigated viral RNA synthesis using NDV minigenome systems to assess the interaction between the NP, P, and L proteins, which showed that the activity of the polymerase-associated proteins were directly related to viral RNA transcription and replication.

Temperature-Sensitive Mutants Isolated from L Cells Persistently Infected with Newcastle Disease Virus | Journal of Virology
Virus mutants (NDVpi) isolated from L cells persistently infected with the Herts strain of Newcastle disease virus have been previously reported by this laboratory to differ from the wild-type virus (NDVo) in several physical and biological properties. It has now been determined that, in addition to these differences, the NDVpi mutants are also spontaneously selected temperature-sensitive mutants. The temperature sensitivity of 10 NDVpi clones was confirmed by temperature inhibition, plaquing efficiency, and single-cycle yield experiments. The cut-off temperature, at which more than 90% of virus replication is inhibited was between 41 and 42 C. All 10 NDVpi clones were also found to be defective in virus-specific ribonucleic acid (RNA) synthesis in infected chick embryo cells at 42 C and are tentatively classified as RNA−. The possible relationships of the temperature sensitivity, the other NDVpi properties, and the maintenance of the persistently infected state are discussed. ...
Newcastle disease virus | Page 2 | The Pirbright Institute
The Newcastle disease virus (NDV) infects domestic and wild birds, having been described in at least 241 species. NDV is an enveloped, single stranded RNA virus within the family of Paramyxoviridae, genus Avulavirus. There are ten serotypes of avian paramyxoviruses named APMV-1 to APMV-10; NDV is known as APMV-1. Depending upon the disease signs and lesions in chicken, NDV can
ENUMERATION OF CELL-INFECTING PARTICLES OF NEWCASTLE DISEASE VIRUS BY THE FLUORESCENT ANTIBODY TECHNIQUE | JEM
A procedure has been developed for the determination of the concentration of infective Newcastle disease virus (NDV) based on the enumeration of singly infected and distributed HeLa cells which are visualized by staining with fluorescent antibody. Infective virus assayed by the fluorescent cell-counting procedure is expressed in terms of cell-infecting units (CIU).. Adsorption of NDV to HeLa cell monolayers reached a plateau 1 to 1.5 hours after inoculation of coverslip cultures, and 12 per cent of the infective particles inoculated failed to adsorb. The half-life of NDV in protein-free Eagles medium at 37°C. was 2.1 hours. There was a linear relationship between virus concentration and the number of infected cells. The coefficient of variation of the mean of replicate determinations of infective NDV was 8.2 per cent. The distribution of single infected HeLa cells in the monolayer corresponded to the Poisson distribution. With NDV the cell-infecting unit (CIU) determined in HeLa cells is ...
Cloning and Expression of the Xylanase Gene From Bacillus Coagulans and the M Gene of Newcastle Disease Virus in Lactococcus...
Lactococcus lactis is being developed as a vaccine delivery system as it bears no threat to animal and human health. It has been used for centuries in the fermentation of foods and is generally recognised as safe. However, a safety factor pertaining to the type of selectable marker present on the vector system poses to be of concern. Chances of the transfer of antibiotic resistance genes, usually employed by vectors as selectable markers, into the natural environment become a possible risk. Therefore, there is a need for the development of ideal vectors without such selectable markers (Dertzbaugh, 1998). The activity of the xylanase gene of Bacillus coagulans ST -6 can be detected on Remazol Brilliant Blue-Xylan (RBB-Xylan) as a clear halo zone against a dark blue background. This characteristic allows xylanase to be used as a selectable chromogenic marker on any vector system. On the other hand, the matrix or membrane (M) protein of Newcastle disease virus (NDV) strain AF 2240 can be useful as ...

Chickens were immunized with Newcastle disease virus inactivated by β propriolactone. The antigen was administered by the intramuscular or intranasal route, and the appearance of HI antibodies in the serum and lungs was followed. Local secretory antibodies in the lung were found only as a consequence of intranasal immunization, whereas serum antibodies were found after administration of antigen by either route.. ...
Barnhealth | Newcastle disease vaccines-A solved problem or a continuous challenge?
Abstract. Newcastle disease (ND) has been defined by the World Organisation for Animal Health as infection of poultry with virulent strains of Newcastle disease virus (NDV). Lesions affecting the neurological, gastrointestinal, respiratory, and reproductive systems are most often observed. The control of ND must include strict biosecurity that prevents virulent NDV from contacting poultry, and also proper administration of efficacious vaccines. When administered correctly to healthy birds, ND vaccines formulated with NDV of low virulence or viral-vectored vaccines that express the NDV fusion protein are able to prevent clinical disease and mortality in chickens upon infection with virulent NDV. Live and inactivated vaccines have been widely used since the 1950s. Recombinant and antigenically matched vaccines have been adopted recently in some countries, and many other vaccine approaches have been only evaluated experimentally. Despite decades of research and development towards formulation of ...
DC immune responses to NDV-Nipah chimeras virus infection | PRiME portal
The ordinary differential equation (ODE) model describes experimental results for human monocyte derived dendritic cells (DCs) infected by individual Nipah virus immune antagonists (P, V, and W) expressed in recombinant Newcastle disease viruses. W antagonizes cellular immune response in the nucleus, whereas P and V do so in the cytoplasm. All three act in both the signaling pathway leading to interferon induction, and the Jak/Stat pathway set into motion by secreted interferon binding to surface receptors. The reaction network is shown below. The model contains 14 species and 49 parameters, of which only the few most sensitive ones were varied to fit the data. The equations of the model are given below. The model aims to capture the essential characteristics of the experimental time-course data for seven of the measured species, namely IFNβm (mRNA of IFNβ), IFNαm (mRNA of IFNα), TNFαm (mRNA of TNFα), IFNαenv (IFNα secreted into the extracellular environment), TNFαenv (TNFα secreted ...
Polymorphisms of the Chicken Mx Gene Promoter and Association with Chicken Embryos Susceptibility to Virulent Newcastle...
Newcastle disease is a devastating viral disease of chicken in low- and middle-income countries where the backyard production system is predominant. Marker-assisted selection of chickens that are resistant to Newcastle disease virus (NDV) is the promising strategy that needs to be explored. )e aim of the present study was to investigate polymorphisms of the promoter region of the chicken Mx gene and association with Kuroiler, Sasso, and local Tanzanian chicken embryos survival variability to virulent NDV infection. Chicken embryos were initially challenged with a minimum lethal dose of virulent NDV suspension and then were followed over time to gather information on their survival variability. Using the survival data, high and less susceptible cohorts were established, and a total of 88 DNA samples from high and less susceptible groups were genotypes by sequencing. Five singlenucleotide polymorphisms (SNPs), which were previously reported, were detected. Interestingly, for the first time, the ...

Virus Shows Promise as Prostate Cancer Treatment
WASHINGTON, DC - February 25, 2013 - A recombinant Newcastle disease virus kills all kinds of prostate cancer cells, including hormone-resistant cells, but leaves normal cells unscathed, according to a paper published online ahead of print in the Journal of Virology. A treatment for prostate cancer based on this virus would avoid the adverse side effects typically associated with hormonal treatment for prostate cancer, as well as those associated with cancer chemotherapies generally, says corresponding author Subbiah Elankumaran of Virginia Polytechnic Institute, Blacksburg. The modified virus is now ready to be tested in preclinical animal models, and possibly in phase I human clinical trials.

Inhibition of fusion by neutralizing monoclonal antibodies to the haemagglutinin-neuraminidase glycoprotein of Newcastle...
The majority of neutralizing monoclonal antibodies (MAbs) to the haemagglutinin-neuraminidase (HN) glycoprotein of Newcastle disease virus prevent attachment of the virus to cellular receptors and inhibits virion-induced fusion from without (FFWO) and fusion from within (FFWI) mediated by the virus glycoprotein-laden infected cell surface. For these antibodies, the inhibition of fusion is presumed to be the result of the prevention of HN-mediated bridging of potential fusion partners. MAbs against antigenic sites 3 and 4 neutralize virus infectivity, but by a mechanism other than the prevention of attachment, the exact nature of which remains to be established. Antibodies to both of these sites effectively inhibit virion-induced FFWO, even when the inducing virus is not infectious. This is consistent with the mechanism of neutralization of these MAbs involving the inhibition of an early, post-attachment step in infection. MAbs to site 3 also inhibit FFWI, but those to site 4 do not, even when added at

BACKGROUND:Newcastle disease virus, in its most pathogenic form, threatens the livelihood of rural poultry farmers where there is a limited infrastructure and service for vaccinations to prevent outbreaks of the virus. Previously reported studies on the host response to Newcastle disease in chickens have not examined the disease under abiotic stressors, such as heat, which commonly experienced by chickens in regions such as Africa. The objective of this study was to elucidate the underlying biological mechanisms that contribute to disease resistance in chickens to the Newcastle disease virus while under the effects of heat stress. RESULTS:Differential gene expression analysis identified genes differentially expressed between treated and non-treated birds across three time points (2, 6, and 10 days post-infection) in Fayoumi and Leghorn birds. Across the three time points, Fayoumi had very few genes differentially expressed between treated and non-treated groups at 2 and 6 days post-infection. ...

USDA APHIS | USDA Confirms Virulent Newcastle Disease in Pet Chickens in Arizona; Not a Food Safety Concern
This case is believed to be connected to the current outbreak of virulent Newcastle disease in California, as tests show the virus is almost identical to the virus causing disease in California. Since May 2018, more than 400 cases of Newcastle disease have been confirmed as part of this southern California outbreak, primarily in backyard exhibition birds.. Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products. Properly cooked poultry products are safe to eat. In very rare instances people working directly with sick birds can become infected. Symptoms are usually very mild, and limited to conjunctivitis and/or influenza-like symptoms. Infection is easily prevented by using standard personal protective equipment. APHIS is working with the Arizona Department of Agriculture to respond to the finding. Federal and State partners are also conducting additional surveillance and testing in the area. It is essential ...
Development of a recombinant Newcastle disease virus-vectored vaccine for infectious bronchitis virus variant strains...
Infectious bronchitis virus (IBV) causes a major disease problem for the poultry industry worldwide. The currently used live-attenuated vaccines have the tendency to mutate and/or recombine with circulating field strains resulting in the emergence of vaccine-derived variant viruses. In order to circumvent these issues, and to develop a vaccine that is more relevant to Egypt and its neighboring countries, a recombinant avirulent Newcastle disease virus (rNDV) strain LaSota was constructed to express the codon-optimized S glycoprotein of the Egyptian IBV variant strain IBV/Ck/EG/CU/4/2014 belonging to GI-23 lineage, that is prevalent in Egypt and in the Middle East. A wild type and two modified versions of the IBV S protein were expressed individually by rNDV. A high level of S protein expression was detected in vitro by Western blot and immunofluorescence analyses. All rNDV-vectored IBV vaccine candidates were genetically stable, slightly attenuated and showed growth patterns comparable to that ...

Infection of Commercial Laying Hens with Newcastle Disease Virus: Diff by Kaylee Rowland, Huaijun Zhou et al.
Exotic Newcastle Disease Virus (ENDV) cause extremely rapid mortality in chickens after exposure to the virus. People rely heavily on poultry to provide protein and income in many places where NDV is not effectively controlled through vaccination and biosecurity. Losses from NDV contribute to worldwide hunger and poverty. It may be possible to use genetic selection to produce chickens that have a stronger immune response in the face of NDV challenge. For genetic selection to be successful, two major elements are required: differences in immune response among chickens and genetic control of these differences. This study clearly demonstrated the existence of both these factors. These findings demonstrate the feasibility of genetic selection to produce chickens that are more resistant to NDV and thereby lessen the burdens of hunger and poverty.

Virulent Newcastle disease - Wikipedia
The precise way in which the presence of NDV induces tumor cell death remains to be clarified and may show variation regarding the strains of NDV used and which type of cancer is targeted. NDV triggers apoptosis in a wide range of cancer cell types via the mitochondrial/intrinsic pathway, through loss of membrane potential and thereby inducing release of cytochrome c in the tumor cell. The results also indicate the extrinsic pathway is activated by TNF-related, apoptosis-inducing ligand-induced, NDV-mediated apoptosis in a late stage. Another study found a hyperfusogenic NDV/F3aa(L289A) with refined abilities to fuse into somatic cells. NDV has aggregating properties causing syncytia formations of tumor cells, which, apart from amplifying immune-based cell killing, also results in necrosis of cells. This pathway was believed to lead to a considerable boost of immune activation and potentially an antitumor response, which was supported by observations of a significant accumulation of ...

RECEPTOR DESTRUCTION BY VIRUSES OF THE MUMPS-NDV-INFLUENZA GROUP | JEM
A strain each of mumps and Newcastle disease virus and five strains of influenza virus were found to be capable of removing all the receptors for this group of viruses from fowl red cells. Five virus strains were tested for their capacity to inactivate the virus hemagglutinin of human plasma and of egg white. In the case of egg white all strains including mumps and Newcastle disease virus inactivated the inhibitor completely, or nearly so. With plasma the influenza strains inactivated the inhibitor completely but mumps and NDV destroyed only that portion of the complex which effected mumps inhibition. The inhibitor for some strains was destroyed more rapidly than that for others and the sequence in which they were destroyed (inhibitor gradient) was similar, regardless of the strain employed. The inhibitor gradient for egg white was very different from that for plasma and these in turn differed significantly from the receptor gradient for fowl red cells.. ...

Viruses | Free Full-Text | Anti-Tumor Effects of an Oncolytic Adenovirus Expressing Hemagglutinin-Neuraminidase of Newcastle...
Oncolytic virotherapy has been an attractive drug platform for targeted therapy of cancer over the past few years. Viral vectors can be used to target and lyse cancer cells, but achieving good efficacy and specificity with this treatment approach is a major challenge. Here, we assessed the ability of a novel dual-specific anti-tumor oncolytic adenovirus, expressing the hemagglutinin-neuraminidase (HN) gene from the Newcastle disease virus under the human telomerase reverse transcriptase (hTERT) promoter (Ad-hTERTp-E1a-HN), to inhibit esophageal cancer EC-109 cells in culture and to reduce tumor burden in xenografted BALB/c nude mice.

The Membrane Integration of the Hemagglutinin-Neuraminidase Glycoprote by Cheryl Anne Wilson
The hemagglutinin-neuraminidase (HN) molecule of Newcastle disease virus (NDV) is an integral membrane glycoprotein that is oriented with its N-terminus in the cytoplasm and its C-terminus external to the infected cell. Single spanning membrane proteins with this type of topology (N-terminus in, C-terminus out) have been classified as Type II glycoproteins, in contrast to the more common Type I glycoproteins, which are oriented in the opposite direction. (C-terminus in, N-terminus out). The membrane integration of HN protein was investigated using a wheat germ translation system to synthesize and integrate HN protein into microsomal membranes in vitro. The insertion and translocation of HN protein into microsomal vesicles was found to occur cotranslationally without signal sequence cleavage. The membrane targeting required both signal recognition particle (SRP) and SRP receptor. Membrane binding assays utilizing HN nascent chain/ribosome/SRP complexes demonstrated that the membrane insertion of HN

Newcastle, New South Wales - Wikipedia
A settlement was again attempted in 1804, as a place of secondary punishment for unruly convicts. The settlement was named Coal River, also Kingstown and then renamed Newcastle, after Englands famous coal port. The name first appeared by the commission issued by Governor King on 15 March 1804 to Lieutenant Charles Menzies of the marine detachment on HMS Calcutta, then at Port Jackson, appointing him superintendent of the new settlement. The new settlement, comprising convicts and a military guard, arrived at the Hunter River on 27 March 1804 in three ships: HMS Lady Nelson, the Resource and the James. The convicts were rebels from the 1804 Castle Hill convict rebellion. The link with Newcastle upon Tyne, England its namesake and also whence many of the 19th century coal miners came, is still obvious in some of the place-names - such as Jesmond, Hexham, Wickham, Wallsend and Gateshead. Morpeth, New South Wales is a similar distance north of Newcastle as Morpeth, Northumberland is ...

Optimization studies for the coupling of bispecific antibodies to...: Ingenta Connect
Tumor vaccines have to provide several signals for T cell activation. Among them, signal 1 (through TCR/CD3) and signal 2 (through CD28) are the most important. We herein describe a procedure to introduce anti-CD3 and anti-CD28 signals into any tumor cell which is susceptible to infection by Newcastle disease virus (NDV). We developed the ATV-NDV tumor vaccine which consists of patient-derived tumor cells (ATV) modified through infection by NDV. We tested for further improvement of vaccine efficiency the addition of two bispecific single-chain antibodies. They bind with one arm to the viral hemagglutinin-neuraminidase (HN) or fusion (F) protein of NDV expressed at the surface of the vaccine cells while the second arm is directed either against CD3 or CD28 of T cells. The aim of this study was to optimize the coupling of these new reagents to the tumor vaccine. When anti-CD3 and anti-CD28 molecules bind to the same anchoring viral molecule (e.g. HN), competition for binding could occur under ...
Role of Host Cellular Membrane Raft Domains in the Assembly and Releas by Jason P. Laliberte
Newcastle disease virus (NDV) belongs to the Paramyxoviridae, a family of enveloped RNA viruses that includes many important human and animal pathogens. Although many aspects of the paramyxovirus life cycle are known in detail, our understanding of the mechanisms regulating paramyxovirus assembly and release are poorly understood. For many enveloped RNA viruses, it has recently become apparent that both viral and host cellular determinants coordinate the proper and efficient assembly of infectious progeny virions. Utilizing NDV as a model system to explore viral and cellular determinants of paramyxovirus assembly, we have shown that host cell membrane lipid raft domains serve as platforms of NDV assembly and release. This conclusion was supported by several key experimental results, including the exclusive incorporation of host cell membrane raftassociated molecules into virions, the association of structural components of the NDV particle with membrane lipid raft domains in infected cells and the

The Effects of Dietary Valine on Performance, SerumAntibody Titre and Bone Mineralization in Broiler Chicks
The present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to Newcastle disease virus vaccination and bone mineralization. The experiment was conducted using 300 Ross 308 male broilers. One-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 20 birds per pen. Chickens were fed one of three dietary treatments with varying concentrations of valine; the first diet was adequate in valine (0% valine), the second and third diets had an excess in valine (0.08% and 0.16% synthetic valine in diet) because valine was added in place of inert filler. The results showed that supplemental dietary valine did not alter either feed intake, body weight gain or feed conversion ratio. Hemagglutination Inhibitiontitre was significantly increased when valine was added to the diet (P|0.05). The supplemental dietary valine had a significant effect on the calcium concentration
