Immunity to Influenza A H9N2 Viruses Induced by Infection and Vaccination [PDF]

Journal of Virology, 2001
ABSTRACTAvian influenza A H9N2 viruses are widespread among domestic poultry and were recently isolated from humans with respiratory illness in China. Two antigenically and genetically distinct groups of H9N2 viruses (G1 and G9) are prevalent in China.

Polysaccharide Adjuvants as Innate Immune Trainers: Bridging Pattern Recognition Receptor (PRR) Activation and Metabolic Reprogramming for Synthetic Vaccine Design

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Polysaccharides modulate immune responses by engaging pattern recognition receptors (PRRs) to induce T‐cell activation. In vaccine design, their particle size critically influences lymph node targeting and activation mechanisms. By engineering structural complexity and multivalent PRR engagement, polysaccharides enable precise modulation of immune ...

Acute lung injury induced by H9N2 virus in mice

Chinese Medical Journal, 2014
Background H9N2 avian influenza viruses (AIVs) have repeatedly caused infections in mammals even humans in many countries. The purpose of our study was to evaluate the acute lung injury (ALI) caused by H9N2 viral infection in mice.

Hemagglutinin reassortment dynamics of the zoonotic H9N2 avian influenza virus

, 2020
The H9N2 avian influenza virus (AIV) has emerged, spread and established itself in poultry globally, in just under 30 years. During this time, multiple reassortants of H9N2 with increased zoonotic potential have been isolated in poultry and humans ...

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Chlamydia psittaci infection increases mortality of avian influenza virus H9N2 by suppressing host immune response

, 2016
International audienceAvian influenza virus subtype H9N2 (H9N2) and Chlamydia psittaci (C. psittaci) are frequently isolated in chickens with respiratory disease. However, their roles in co-infection remain unclear.

Antigenic and Molecular Characterization of Avian Influenza A(H9N2) Viruses, Bangladesh

Emerging Infectious Diseases, 2013
Human infection with avian influenza A(H9N2) virus was identified in Bangladesh in 2011. Surveillance for influenza viruses in apparently healthy poultry in live-bird markets in Bangladesh during 2008–2011 showed that subtype H9N2 viruses are isolated ...
