The Viral Replication Complex Is Associated with the Virulence of Newcastle Disease Virus [PDF]

open access: yes, 2010
Virulent strains of Newcastle disease virus ([NDV] also known as avian paramyxovirus type 1) can be discriminated from low-virulence strains by the presence of multiple basic amino acid residues at the proteolytic cleavage site of the fusion (F) protein.

Mouse-adapted H9N2 influenza A virus PB2 protein M147L and E627K mutations are critical for high virulence. [PDF]

open access: yesPLoS ONE, 2012
H9N2 influenza viruses have been circulating worldwide in multiple avian species and have repeatedly infected humans to cause typical disease. The continued avian-to-human interspecies transmission of H9N2 viruses raises concerns about the possibility of

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.

An environmentally safe and tolerant microbial insecticide utilizing Helicoverpa armigera single nucleopolyhedrovirus (HearNPV-TR)

open access: yesEgyptian Journal of Biological Pest Control, 2022
Background Baculoviruses are significant biocontrol agents of pests in agriculture; however, ultraviolet light B (UV-B) and high temperature inactivate them in the environment within a short time.

Species-Specific Contribution of the Four C-Terminal Amino Acids of Influenza A Virus NS1 Protein to Virulence [PDF]

open access: yes, 2010
Large-scale sequence analyses of influenza viruses revealed that nonstructural 1 (NS1) proteins from avian influenza viruses have a conserved C-terminal ESEV amino acid motif, while NS1 proteins from typical human influenza viruses have a C-terminal RSKV

Differential contribution of PB1-F2 to the virulence of highly pathogenic H5N1 influenza A virus in mammalian and avian species [PDF]

open access: yes, 2011
Highly pathogenic avian influenza A viruses (HPAIV) of the H5N1 subtype occasionally transmit from birds to humans and can cause severe systemic infections in both hosts.

The Evolutionary Pathway to Virulence of an RNA Virus [PDF]

open access: yesCell, 2017
Paralytic polio once afflicted almost half a million children each year. The attenuated oral polio vaccine (OPV) has enabled world-wide vaccination efforts, which resulted in nearly complete control of the disease. However, poliovirus eradication is hampered globally by epidemics of vaccine-derived polio.

Identification and characterization of a novel non-structural protein of bluetongue virus [PDF]

open access: yes, 2011
Bluetongue virus (BTV) is the causative agent of a major disease of livestock (bluetongue). For over two decades, it has been widely accepted that the 10 segments of the dsRNA genome of BTV encode for 7 structural and 3 non-structural proteins.

Schmallenberg virus pathogenesis, tropism and interaction with the innate immune system of the host [PDF]

open access: yes, 2013
Schmallenberg virus (SBV) is an emerging orthobunyavirus of ruminants associated with outbreaks of congenital malformations in aborted and stillborn animals.

Adaption of seasonal H1N1 influenza virus in mice. [PDF]

open access: yesPLoS ONE, 2011
The experimental infection of a mouse lung with influenza A virus has proven to be an invaluable model for studying the mechanisms of viral adaptation and virulence.
