Ecology of Low Pathogenicity Avian Influenza Virus H7 in Wild Birds in South‐Eastern Australia Prior to Emergence of High Pathogenicity Avian Influenza H7 in Poultry

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT Background Adding to the global burden of high pathogenicity avian influenza (HPAI) H5N1, five HPAI H7 outbreaks occurred globally in 2024. Of these, three occurred in South‐East Australia, with the independent emergence of HPAI H7N9, H7N8 and H7N3, resulting in the destruction of 2 million poultry.

Genomic characterization of equine influenza A subtype H3N8 viruses by long read sequencing and functional analyses of the PB1-F2 virulence factor of A/equine/Paris/1/2018

Veterinary Research
Equine influenza virus (EIV) remains a threat to horses, despite the availability of vaccines. Strategies to monitor the virus and prevent potential vaccine failure revolve around serological assays, RT-qPCR amplification, and sequencing the viral ...

Surveillance of Migratory Shorebirds and Seabirds in 2024 in Australia Reveals Incursions of a Diversity of Low Pathogenicity Avian Influenza Viruses, but Not High Pathogenicity Avian Influenza H5N1

Influenza and Other Respiratory Viruses, Volume 20, Issue 6, June 2026.
ABSTRACT Background The current panzootic of high pathogenicity avian influenza (HPAI) H5N1 has been catastrophic for wildlife, and following substantial geographic spread, clade 2.3.4.4b is found in every region aside from Oceania. Herein, we report the results of our third year of targeted surveillance of incoming migratory seabirds and shorebirds ...

First detection of influenza A virus subtypes H1N1 and H3N8 in the Antarctic region: King George Island, 2023

Problems of Virology
Relevance. Influenza A virus is characterized by a segmented single-stranded RNA genome. Such organization of the virus genome determines the possibility of reassortment, which can lead to the emergence of new virus variants. The main natural reservoir of most influenza A virus subtypes are wild waterfowl.

Association between nasal shedding and fever that influenza A (H3N2) induces in dogs

Virology Journal, 2011
Background Avian origin canine influenza virus was reported in Korea. The dog to dog contact transmission of the avian origin canine influenza virus (CIV) H3N2 and CIV H3N8 was shown by experimental contact transmission.

Virological evaluation of avian influenza virus persistence in natural and anthropic ecosystems of Western Siberia (Novosibirsk Region, summer 2012). [PDF]

PLoS ONE, 2014
BACKGROUND:Wild aquatic birds, reservoir of low-pathogenicity (LP) avian influenza viruses (AIVs), congregate in huge numbers in Western Siberia wetlands, where major intra- and inter-continental bird flyways overlap. In 2005 and 2006, highly pathogenic (

Evidence of a fixed internal gene constellation in influenza A viruses isolated from wild birds in Argentina (2006–2016)

Emerging Microbes and Infections, 2018
Wild aquatic birds are the major reservoir of influenza A virus. Cloacal swabs and feces samples (n = 6595) were collected from 62 bird species in Argentina from 2006 to 2016 and screened for influenza A virus.

Evidence of Influenza A Virus Infection Among Cattle in Nigeria

Advances in Public Health, Volume 2026, Issue 1, 2026.
Sequel to the 2024 highly pathogenic avian influenza (HPAI) virus H5N1 outbreak among cattle in the United States of America, it became imperative to investigate the exposure of Nigerian cattle, a major source of much needed animal protein, to avian influenza virus (AIV).

Complex Reassortment Dynamics of H9N2 Avian Influenza Viruses in Xinjiang, China: Implications for Zoonotic Spillover

Influenza and Other Respiratory Viruses, Volume 19, Issue 10, October 2025.
ABSTRACT Background H9N2 avian influenza viruses (AIVs) donate their genes to other subtype AIVs, posing significant threats to poultry industries and public health due to their endemicity and zoonotic potential. This study investigates the molecular evolution, reassortment, and mutations of the H9N2 isolates from the live poultry markets (LPMs) in ...

Molecular Mechanisms Underlying Response to Influenza in Grey Seals (Halichoerus grypus), a Potential Wild Reservoir

Molecular Ecology, Volume 34, Issue 15, August 2025.
ABSTRACT RNA viruses are infamous for their ability to cross species barriers, posing threats to global health and security. Influenza A virus (IAV) is naturally found in avian hosts but periodically spills over into marine wildlife. IAV outbreaks occur in the Northwest Atlantic, but grey seals (Halichoerus grypus) appear to be less susceptible to IAV ...
