Isolation, sequencing and phylogenetic analysis of the hemagglutinin, neuraminidase and nucleoprotein genes of the Chilean equine influenza virus subtypes H7N7 and H3N8 [PDF]

Biological Research, 2005
We report here on the isolation and sequencing of the hemagglutinin, neuraminidase and nucleoprotein genes of the Chilean equine influenza virus subtypes H7N7 (A⁄equi-1⁄Santiago⁄77, Sa77) and H3N8 (A⁄equi-2⁄Santiago⁄85,

Cocirculation of Two Distinct Lineages of Equine Influenza Virus Subtype H3N8 [PDF]

Journal of Clinical Microbiology, 1999
ABSTRACT Direct amplification and sequencing of the hemagglutinin (HA) genes of equine influenza virus subtype H3N8 was undertaken in order to characterize strains of this virus circulating in Sweden. The majority of viruses from outbreaks during 1997 analyzed belonged to the American lineage of H3 equine influenza, and one strain was shown ...

From Surfaces to Spillover: Environmental Persistence and Indirect Transmission of Influenza A(H3N8) Virus. [PDF]

Microorganisms
Avian influenza viruses (AIVs) pose a significant zoonotic threat, with the emerging H3N8 subtype raising increasing concern due to sporadic human infections. Current strategies for risk assessment of novel AIVs primarily rely on genetic surveillance and

Assessment of the public health risk of novel reassortant H3N3 avian influenza viruses that emerged in chickens [PDF]

mBio
Influenza A (H3N2) viruses are historically responsible for the 1968 Hong Kong flu pandemic. Since then, H3N2 has continued to circulate as a seasonal influenza virus in humans.

Characterisation of a novel chicken-derived H3N3 avian influenza virus detected in China in 2023: Pathogenicity and immunogenicity. [PDF]

PLoS One
The poultry industry faces a constant threat from the mutation and transmission of avian influenza viruses (AIVs). While waterfowl and wild birds are natural hosts of H3N3 AIV, reports of H3N3 infections in chickens are limited.

Evidence of an emerging triple-reassortant H3N3 avian influenza virus in China

BMC Genomics
The H3 subtype of avian influenza virus (AIV) stands out as one of the most prevalent subtypes, posing a significant threat to public health. In this study, a novel triple-reassortant H3N3 AIV designated A/chicken/China/16/2023 (H3N3), was isolated from ...
