Despite intensive vaccination programs in many countries, including China, Newcastle disease has been reported sporadically and is still a significant threat to the poultry industry in China. Newcastle disease virus (NDV) is infectious for at least 250 bird species, but the role of wild birds in virus epidemiology remains largely unknown. Fourteen NDV isolates were obtained from 2040 samples collected from wild birds or the environment in Guangdong province, southern China, from 2013 to 2015. The isolation rate was the highest in the period of wintering and lowest during the periods of spring migration, nesting, and postnesting...

Oncolytic virotherapy is a promising novel approach that overcomes the limitations posed by radiation and chemotherapy. In this study, the oncolytic efficacy of a recombinant Newcastle disease virus (rNDV) BC-KLQL-GFP, against prostate cancer stem-like/tumor initiating cells was evaluated. Xenograft derived prostaspheres (XPS) induced tumor more efficiently than monolayer cell derived prostaspheres (MCPS) in nude mice. Primary and secondary XPS show enhanced self-renewal and clonogenic potential compared to MCPS...

A novel immunosensor for detecting Newcastle disease virus (NDV) was developed using excessively tilted fiber grating (Ex-TFG) coated with gold nanospheres (AuNs). AuNs were coated on the Ex-TFG surface via Au-S bonds using 3-mercaptopropyltrimethoxysilane (MPTMS), and the activated staphylococcal protein A (SPA) was linked to AuNs by covalent bonds via cysteamine. AuNs greatly enhanced the impact of the analyte on the fiber cladding mode through the local surface Plasmon resonance (LSPR) effect, thus improving the detection limit and sensitivity of the immunosensor...

Leader sequence, located at the 3' terminus of paramyxovirus genomes, determines the degree of viral transcription and replication. The essential nucleotides in the leader sequence that influence viral propagation, however, have not been investigated in detail. In the present study, we show that polymerase complex of human parainfluenza virus type 2 (hPIV2) uses a luciferase-encoding hPIV2 mini-genome possessing the leader sequence from other closely related viruses as a template. Furthermore, we demonstrate that although hPIV2 polymerase complex can recognize the leader sequence of hPIV4B, mumps virus (MuV) and PIV5 as well as Newcastle disease virus (NDV), it cannot recognize measles virus, hPIV1, Sendai virus (SeV) or hPIV3...

To investigate the exact effects of different origins of Newcastle disease virus (NDV) hemagglutinin-neuraminidase (HN) protein to the biological characteristics of the virus, we systematically studied the correlation between the HN protein and NDV virulence by exchanging the HN of velogenic or lentogenic NDV strains with the HN from other strains of different virulence. The results revealed that the rSG10 or rLaSota derivatives bearing the HN gene of other viruses exhibited decreased or increased hemadsorption (HAd), neuraminidase and fusion promotion activities...

Newcastle disease (ND) is an economically important and highly contagious disease of wild and domestic avian species. Despite extensive vaccination efforts of industrial poultry, Newcastle disease virus (NDV) outbreaks causing significant economic losses still occur. Rural chickens may act as a potential reservoir of NDVs for commercial poultry due to poor biosecurity and inadequate vaccination. The aim of this study was to investigate phylogenetic relationship and molecular characterization of eight NDVs isolated from backyard poultry during 2011-2013...

Rescue of negative-sense single-stranded RNA viruses ((-)ssRNA virus), generally requires the handling of a large number of plasmids to provide the virus genome and essential components for gene expression and genome replication. This constraint probably renders reverse genetics of (-)ssRNA virus more complex and less efficient. Some authors have shown that the fewer the plasmids, the more efficient reverse genetics is for segmented RNA virus. However, it is not clear if the same applies for (-)ssRNA, such as Newcastle disease virus (NDV)...

Fibrosarcoma is a locally aggressive malignant tumor with a high recurrence rate, so that wide excisional surgery is necessary for treatment. However, it is often difficult to resect with a sufficient margin of excision at the site of tumor infiltration. Recombinant tumor vaccine therapy is a useful method to induce specific immunity. In this study, we have shown its utility as a candidate for therapy by applying a recombinant Newcastle disease virus (rNDV) tumor vaccine (rNDV-TV). Although the therapeutic effect of similar viruses has been examined in several tumors, the vaccination efficacy against fibrosarcoma has not been demonstrated until now...

In the case of Newcastle disease virus, multiple factors such as host adaptation, immune response evasion, and selective pressures have been suggested to result in evolution of viruses and the emergence of genetic variants. Multiple studies on virus classification and global epidemiological links have yielded consistent data. Here, we have performed a molecular analysis study of circulating Newcastle disease viruses in Iran (1995-2016). According to evolutionary divergences, subgenotype VIg, VIj, VIIj, VIId, XIIIa and XIIId isolates have been circulating in the country during a 21-year period...

Newcastle disease virus (NDV) is a contagious agent of Newcastle disease in avian species and seriously affects the poultry industry. The cleavage site of the viral F protein (Fcs) is a key determinant of membrane fusion and viral virulence. In this study, we investigated the precise effect of variable amino acid sequences of the Fcs on fusogenic activity. Based on viral pathogenicity, the Fcs sequences of natural isolates (n = 1572) are classified into eight types of virulent Fcs (VFcs) with the motif "G/R/K-R-Q/R/K-R/K-R↓F" and ten types of the avirulent Fcs (AFcs) with the motif "G/R/E-R/K/Q-Q-G/E-R↓L"...

Pancreatic cancer is the 8(th) most common cause of cancer-related deaths worldwide and the tumor with the poorest prognosis of all solid malignancies. In 1957 it was discovered that Newcastle disease virus (NDV) has oncolytic properties on tumor cells. To study the oncolytic properties of NDV in pancreatic cancer a single dose was administered intravenously in a syngenic orthotopic tumor model employing two different murine pancreatic adenocarcinoma cell lines (DT6606PDA, Panc02). Tumor growth was monitored and immune response was analyzed...

H9 subtype avian influenza virus causes worldwide epidemic, resulting in enormous economic losses of poultry production. In the present study, an indirect ELISA method was established for more accurate and specific detection. The recombinant protein of the globular head domain of HA of H9 subtype avian influenza virus was used as antigen. Specific blocking buffers and dilution buffers were determined to increase the sensitivity and specificity. The sensitivity of ELISA was higher than that of hemagglutination inhibition (HI) test...

Vesicular stomatitis virus (VSV) and rabies and Chandipura viruses belong to the Rhabdovirus family. VSV is a common laboratory virus to study viral evolution and host immune responses to viral infection, and recombinant VSV-based vectors have been widely used for viral oncolysis, vaccination, and gene therapy. Although the tropism of VSV is broad, and its envelope glycoprotein G is often used for pseudotyping other viruses, the host cellular components involved in VSV infection remain unclear. Here, we demonstrate that the host protein leucine-rich repeat-containing G protein-coupled receptor 4 (Lgr4) is essential for VSV and VSV-G pseudotyped lentivirus (VSVG-LV) to infect susceptible cells...

Maternally derived antibodies (MDAs) are critical for offspring protection during the first days of life. However, due to their short half-life (3-5 days), MDA levels decline rapidly and by 8-15 days post-hatch drop to below protective levels. In addition, MDAs against a specific pathogen often impede the efficient protective immune response to that pathogen by the new-born following vaccination. The combination of these two phenomena generates a gap in protection in the period between loss of MDA protection and development of vaccine-induced protective antibodies...

Newcastle disease (ND) leading to heavy economic losses to the poultry industry worldwide is caused by Newcastle disease virus (NDV). Even though intensive vaccination programs have been implemented in many countries, virulent NDV can still be frequently isolated in well-vaccinated flocks. We compared the protection efficiency of LaSota and two sub-genotype VIId vaccines, NDV/AI4 and NDV O/AI4, in which NDV O/AI4 was constructed by replacing the hemagglutinin-neuraminidase (HN) gene of the vaccine strain NDV/AI4 with that from the variant NDV strain JS-14-12-Ch by the cross hemagglutination inhibition test and immune protection test...

Although vaccination has been hugely successful in protecting birds against infection by the New castle disease virus (NDV), newly-emerged highly virulent strains have been found to overcome established immune protection and threaten the poultry industry. The need to improve the immunization efficacy is, therefore, urgent. Here, we tested the potential immunostimulatory adjuvant activity of the adenoviral-expressed recombinant chicken granulocyte monocyte colony stimulating factor (rchGM-CSF) in an inactivated Newcastle Disease Virus (NDV) vaccine...
