Competition between influenza A virus subtypes through heterosubtypic immunity modulates re-infection and antibody dynamics in the mallard duck.

PLoS Pathogens, 2017
Our overall hypothesis is that host population immunity directed at multiple antigens will influence the prevalence, diversity and evolution of influenza A virus (IAV) in avian populations where the vast subtype diversity is maintained.

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

Influenza and Other Respiratory Viruses, Volume 20, Issue 5, May 2026.
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

A novel M2e based flu vaccine formulation for dogs. [PDF]

PLoS ONE, 2013
BACKGROUND:The USA 2004 influenza virus outbreak H3N8 in dogs heralded the emergence of a new disease in this species. A new inactivated H3N8 vaccine was developed to control the spread of the disease but, as in humans and swine, it is anticipated that ...

Longitudinal Surveillance of Influenza A Virus Exposure in Wild Boars (Sus scrofa) in Spain (2015–2023): Serologic and Virologic Evidence of Subtype Infections and H5N1 Spillover Risk

Zoonoses and Public Health, Volume 73, Issue 3, Page 191-204, May 2026.
ABSTRACT Introduction Influenza A viruses (IAVs) are responsible for respiratory infections in a wide range of species, including birds, swine and humans. The role of wild boar (Sus scrofa) in IAV epidemiology remains underexplored. Here, we present a longitudinal serologic and virologic surveillance study of wild boars in Spain from 2015 to 2023 ...

A novel kirkovirus may be associated with equine gastrointestinal disease

Equine Veterinary Journal, Volume 58, Issue 2, Page 414-422, March 2026.
Abstract Background Many cases of equine enterocolitis are suspected to be infectious in nature, but no pathogen is identified in many cases. Objectives Perform next‐generation sequencing on faeces collected from cases of equine enterocolitis for the presence of novel viruses and determine if an identified novel virus is associated with cases of equine

Influenza viruses in adult dogs raised in rural and urban areas in the state of São Paulo, Brazil

Revista do Instituto de Medicina Tropical de São Paulo, 2012
In 1970, searching for the interspecies transmission of influenza viruses led to the first study on influenza viruses in domestic animals. Birds and mammals, including human beings, are their natural hosts; however, other animals may also play a role in ...

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).

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.

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 ...
