The synergistic effect of residues 32T and 550L in the PA protein of H5 subtype avian influenza virus contributes to viral pathogenicity in mice.

PLoS Pathogens, 2023
The avian influenza virus (AIV) PA protein contributes to viral replication and pathogenicity; however, its interaction with innate immunity is not well understood.

Potential risk zones and climatic factors influencing the occurrence and persistence of avian influenza viruses in the environment of live bird markets in Bangladesh

One Health, 2023
Live bird markets (LBMs) are critical for poultry trade in many developing countries that are regarded as hotspots for the prevalence and contamination of avian influenza viruses (AIV).

Serologic Evidence of Occupational Exposure to Avian Influenza Viruses at the Wildfowl/Poultry/Human Interface

Microorganisms, 2021
Ecological interactions between wild aquatic birds and outdoor-housed poultry can enhance spillover events of avian influenza viruses (AIVs) from wild reservoirs to domestic birds, thus increasing the related zoonotic risk to occupationally exposed ...

Evolution and Reassortment of H6 Subtype Avian Influenza Viruses

Viruses, 2023
The H6 subtype of avian influenza virus (H6 AIV) is the most detected AIV subtype in poultry and wild birds. It causes economic losses to the poultry industry, and the most important, H6 AIV may have the ability to infect mammals, which is a great threat

Expression and Conservation of Apolipoprotein AIV in an Avian Species [PDF]

Journal of Biological Chemistry, 1998
In birds, intestinally derived lipoproteins are thought to be secreted directly into the portal vein rather than to enter the circulation via the lymphatic system as in mammals. Hepatic clearance of these so-called portomicrons must be rapid, but the protein(s) mediating their catabolism, presumably analogues of the 36-kDa mammalian apolipoprotein E ...

Naked-eye counting of pathogenic viruses by phage-gold nanobiomaterials as probes

Materials Today Advances, 2021
Early and sensitive detection of avian influenza virus (AIV) such as H9N2 is needed as AIV threatens human health and the food industry. Here, we developed an ultrasensitive and naked-eye counting strategy for quantifying AIV by two probes. One probe was

Efficacy of recombinant Newcastle disease virus expressing HA protein of H9N2 Avian influenza virus in respiratory and intestinal tract

Poultry Science, 2022
: H9N2 subtype avian influenza virus (AIV) is a low pathogenic AIV, which is widely prevalent all over the world. The infection of H9N2 AIV often leads to secondary infection with other pathogens, causing serious economic losses to poultry industry.

A small-scale study on airborne transmission of H9N2 avian influenza virus under field conditions

Journal of Infection in Developing Countries, 2018
Introduction: H9N2 avian influenza viruses (AIV) can transmit in chicken flocks through direct contact and aerosols. Nevertheless, data on airborne transmission of AIV is very limited, especially under field conditions. To fill this literature gap, this
