Passaging of a Newcastle disease virus pigeon variant in chickens results in selection of viruses with mutations in the polymerase complex enhancing virus replication and virulence [PDF]

open access: yes, 2010
Some Newcastle disease virus (NDV) variants isolated from pigeons (pigeon paramyxovirus type 1; PPMV-1) do not show their full virulence potential for domestic chickens but may become virulent upon spread in these animals.

Oncolytic Newcastle disease virus activation of the innate immune response and priming of antitumor adaptive responses in vitro

open access: yesCancer Immunology and Immunotherapy, 2020
Oncolytic virus (OV) therapy is an emerging approach with the potential to redefine treatment options across a range of cancer indications and in patients who remain resistant to existing standards of care, including immuno-oncology (IO) drugs. MEDI5395,

Structural and functional relationship between the receptor recognition and neuraminidase activities of the Newcastle disease virus hemagglutinin-neuraminidase protein: Receptor recognition is dependent on neuraminidase activity [PDF]

open access: yes, 2001
The terminal globular domain of the paramyxovirus hemagglutinin-neuraminidase (HN) glycoprotein spike has a number of conserved residues that are predicted to form its neuraminidase (NA) active site, by analogy to the influenza virus neuraminidase ...

Synthesis of IFN-β by Virus-Infected Chicken Embryo Cells Demonstrated with Specific Antisera and a New Bioassay [PDF]

open access: yes, 2004
Transcripts of interferon-α(IFN-α) and IFN-β genes are present in virus-infected chicken cells, but because of a lack of appropriate assays and reagents, it was unclear if biologically active IFN-β is secreted.

Evolutionary Dynamics of H5 Highly Pathogenic Avian Influenza Viruses (Clade 2.3.4.4B) Circulating in Bulgaria in 2019–2021

open access: yesViruses, 2021
The first detection of a Highly Pathogenic Avian Influenza (HPAI) H5N8 virus in Bulgaria dates back to December 2016. Since then, many outbreaks caused by HPAI H5 viruses from clade 2.3.4.4B have been reported in both domestic and wild birds in different

Transcriptional map for Newcastle disease virus [PDF]

open access: yesJournal of Virology, 1980
A transcriptional map of Newcastle disease virus was determined by measuring the kinetics of UV inactivation of the transcription of individual genes and of viral infectivity. The inactivation of single genes was monitored by measuring the reduction in the accumulation of viral gene products in vivo and in vitro.

Molecular characterization of some strains of Newcastle disease virus isolated in Province of Vojvodina, Republic of Serbia [PDF]

open access: yesActa Veterinaria, 2012
Five strains of Newcastle disease virus (NDV) were obtained from poultry in Vojvodina, Serbia during the outbreaks in 2006 and 2007. These isolates were confirmed and genotypically characterized by reverse transcription polymerase chain reaction (RT ...
