Identification of Unique and Conserved Neutralizing Epitopes of Vestigial Esterase Domain in HA Protein of the H9N2 Subtype of Avian Influenza Virus. [PDF]

Viruses, 2022
The H9N2 subtype of avian influenza virus (AIV) has been reported to infect not only birds, but also humans. The hemagglutinin (HA) protein is the main surface antigen of AIV and plays an important role in the viral infection.

Avian-to-human transmission of H9N2 subtype influenza A viruses: Relationship between H9N2 and H5N1 human isolates [PDF]

Proceedings of the National Academy of Sciences, 2000
In 1997, 18 cases of influenza in Hong Kong (bird flu) caused by a novel H5N1 (chicken) virus resulted in the deaths of six individuals and once again raised the specter of a potentially devastating influenza pandemic. Slaughter of the poultry in the live bird markets removed the source of infection and no further human cases of H5N1 infection have ...

Chicken Origin Tribasic H9N2 Avian Influenza Virus Induces Potent Early Antiviral Response With Low Pathogenicity in Japanese Quails. [PDF]

Vet Med Sci
This study gives valuable insights into host–pathogen interaction and confirms that the circulating tribasic H9N2 virus remains phenotypically low pathogenic in Japanese quails in Bangladesh but cause long‐term impairment of important productivity parameters (weight gain, laying rates).
