Pathogenicity of Novel H3 Avian Influenza Viruses in Chickens and Development of a Promising Vaccine [PDF]

Viruses
Since 2022, three cases of human infections of novel H3N8 avian influenza viruses (AIVs) have been confirmed in China. Given the potential for significant public health implications, the prompt detection and containment of the virus is particularly ...

The genetic analysis of broiler-origin h9n2 influenza virus with internal genes highly homologous to the recent human h3n8 virus [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2023
The most prevalent subtype of avian influenza worldwide, H9N2, not only threatens human health and causes enormous financial losses in the poultry sector but also has the potential to be transmitted directly or indirectly between other species.

Emergence and Rapid Spread of a New Reassortant High Pathogenicity H5N1 Clade 2.3.4.4b Avian Influenza Virus in Nigeria. [PDF]

Influenza Other Respir Viruses
ABSTRACT Over the past two decades, West Africa has experienced recurrent incursions of Goose/Guangdong‐lineage highly pathogenic avian influenza (HPAI) A(H5N1), with Nigeria as a hotspot for repeated introductions and sustained circulation. Since 2021, European‐origin clade 2.3.4.4b H5Nx genotypes, particularly EA‐2020‐C, have predominated in regional

Human infection of avian influenza A H3N8 virus and the viral origins: a descriptive study.

The Lancet Microbe, 2022
BACKGROUND The H3N8 avian influenza virus (AIV) has been circulating in wild birds, with occasional interspecies transmission to mammals. The first human infection of H3N8 subtype occurred in Henan Province, China, in April, 2022. We aimed to investigate

Adaptive Heterosubtypic Immunity to Low Pathogenic Avian Influenza Viruses in Experimentally Infected Mallards. [PDF]

PLoS ONE, 2017
Mallards are widely recognized as reservoirs for Influenza A viruses (IAV); however, host factors that might prompt seasonality and trends in subtype diversity of IAV such as adaptive heterosubtypic immunity (HSI) are not well understood.

Evolutionary features of a prolific subtype of avian influenza A virus in European waterfowl

bioRxiv, 2021
Avian influenza A virus (AIV) is ubiquitous in waterfowl, and detected annually at high prevalence in waterfowl during the Northern Hemipshere autumn. Some AIV subtypes are globally common in waterfowl, such as H3N8, H4N6, and H6N2, and are detected in ...

Evidence that HA‐G228S and PB2‐D153V mutations upon viral growth of H3N8 influenza virus are associated with severe pathogenesis in human infections

Influenza and Other Respiratory Viruses, 2023
Dear Editor, H3N8, a subtype of the Influenza A virus, was first identified in 1963. It has been detected in birds and mammals, such as camels, cats, dogs, horses, pigs and seals.

Influenza A Virus (H3N8) in Dogs with Respiratory Disease, Florida

Emerging Infectious Diseases, 2008
In 2004, canine influenza virus subtype H3N8 emerged in greyhounds in the United States. Subsequent serologic evidence indicated virus circulation in dog breeds other than greyhounds, but the virus had not been isolated from affected animals. In 2005, we
