Synergistic effects of PA (S184N) and PB2 (E627K) mutations on the increased pathogenicity of H3N2 canine influenza virus infections in mice and dogs

open access: yesJournal of Virology
As companion animals, dogs are susceptible to various subtypes of influenza A virus (IAV), with the H3N2 and H3N8 subtypes of canine influenza virus (CIV) stably circulating among canines.

Lower cellular immune responses to influenza A (H3N2) in the elderly

open access: yesJournal of Medical Virology, 2009
AbstractInfluenza epidemic is an important cause of severe illness in the elderly. Age‐dependent morbidity of influenza in the elderly is associated with weakened immunity. The baseline age‐related memory T cell activity in Chinese persons who are exposed to influenza virus through natural infection, are associated with the protective response to the ...

Low population serum microneutralization antibody titer against the predominating influenza A(H3N2) N121K virus during the severe influenza summer peak of Hong Kong in 2017

open access: yesEmerging Microbes and Infections, 2018
The 2017 Hong Kong influenza A(H3N2) summer season was unexpectedly severe. However, antigenic characterization of the 2017 circulating A(H3N2) viruses using ferret antisera did not show significant antigenic drift.

Chronology of H3N2 human influenza virus surface glycoprotein adaptation from 1968 to 2019 reveals a surge of adaptation between 1997 and 2002

open access: yesJournal of Virology
Subtype H3N2 influenza A viruses (IAVs), which emerged in 1968 to cause a pandemic, have shown continual circulation and adaptation that has necessitated frequent updates of candidate vaccine viruses.

Genetic characterization of an H3N2 canine influenza virus strain in China in 2023—acquisition of novel human-like amino acid substitutions

open access: yesFrontiers in Veterinary Science
Around 2005, influenza A virus (IAV) once again crossed species barriers and established a stable lineage within canine populations. Currently, avian-origin H3N2 canine influenza virus (CIV) is the only strain of influenza that is stably circulating in ...

Emergence of Novel Reassortant H3N2 Avian Influenza Viruses in Southern China: Genetic Complexity and Pathogenicity in Chickens and Mice

open access: yesAnimals
H3N2 subtype avian influenza virus (AIV) is prevalent in poultry and wild birds and typically causes asymptomatic or mild respiratory infections. However, genetic reassortment between H3N2 and other AIV subtypes generates novel strains capable of ...
