Chlamydia psittaci Triggers the Invasion of H9N2 Avian Influenza Virus by Impairing the Functions of Chicken Macrophages

Animals, 2020
In a pilot study, simultaneous infection with Chlamydia psittaci (C. psittaci) and H9N2 virus induced 20% mortality and severe avian airsacculitis, shedding light on animal models of poultry respiratory diseases.

Identification of key residues involved in the neuraminidase antigenic variation of H9N2 influenza virus

Emerging Microbes and Infections, 2021
Influenza A H9N2 virus causes economic loss to the poultry industry and has likely contributed to the genesis of H5N1 and H7N9 viruses. The neuraminidase (NA) of H9N2 virus, like haemagglutinin, is under antibody selective pressure and may undergo ...

All-trans retinoic acid increases the pathogenicity of the H9N2 influenza virus in mice

Virology Journal, 2022
Background The H9N2 virus can infect not only birds but also humans. The pathogenicity of H9N2 virus infection is determined by an excessive immune response in the lung.

Maternal-derived antibodies hinder the antibody response to H9N2 AIV inactivated vaccine in the field

Animal Diseases, 2022
The H9N2 subtype avian influenza virus (AIV) inactivated vaccine has been used extensively in poultry farms, but it often fails to stimulate a sufficiently high immune response in poultry in the field, although it works well in laboratory experiments ...
