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

Animal Diseases, 2022
AbstractThe 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; hence, the virus still causes economic damage every year and poses a potential threat to ...

Molecular and Antigenic Characterization of Avian H9N2 Viruses in Southern China

Microbiology Spectrum, 2022
The H9N2 subtype avian influenza virus (AIV) has become endemic in poultry globally; however due to its low pathogenicity, it is not under primary surveillance and control in many countries.

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

Adaptation of H9N2 AIV in guinea pigs enables efficient transmission by direct contact and inefficient transmission by respiratory droplets [PDF]

Scientific Reports, 2015
AbstractH9N2 avian influenza viruses circulate worldwide in poultry and have sporadically infected humans, raising concern whether H9N2 viruses have pandemic potential. Here, we use a guinea pig model to examine whether serial passage results in adaptive viral changes that confer a transmissible phenotype to a wild-type H9N2 virus.

LPAIV H9N2 drives the differential expression of goose interferons and proinflammatory cytokines in both in vitro and in vivo studies

Frontiers in Microbiology, 2016
Geese, as aquatic birds, are an important natural reservoir of avian influenza virus (AIV). To characterize the innate antiviral immune response against AIV H9N2 strain infection in geese as well as the probable relationship between the expression of ...

The generation of hemagglutinin monoclonal antibodies against H9N2 influenza virus

Animal Diseases, 2023
H9N2 avian influenza viruses (AIVs) are widely distributed, causing continuous outbreaks in poultry and sporadic infections in humans. Vaccination is the primary method used to prevent and control H9N2 AIV infection.
