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. [PDF]

Zoonoses Public Health
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 ...

Evaluation of a novel real-time polymerase chain reaction assay for identifying H3 equine influenza virus in Kazakhstan [PDF]

Veterinary World, 2023
Background and Aim: Equine influenza (EI) is a highly contagious disease that causes fever and upper respiratory tract inflammation. It is caused by influenza virus A, belonging to the Orthomyxoviridae family, with subtypes H3N8 and H7N7.

Defective interfering type A equine influenza virus (H3N8) protects mice from morbidity and mortality caused by homologous and heterologous subtypes of influenza A virus

Journal of General Virology, 1994
Intranasal administration of defective interfering A/equine/Newmarket/7339/79 (H3N8) influenza virus (DI EQV) protected mice from otherwise lethal intranasal infection with homologous virus (EQV) or with the heterologous subtypes A/WSN (H1N1) or A/PR/8/34 (H1N1). Such protected mice showed little or no sign of clinical disease.

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.

Heterosubtypic immunity increases infectious dose required to infect Mallard ducks with Influenza A virus. [PDF]

PLoS ONE, 2018
Previous field and experimental studies have demonstrated that heterosubtypic immunity (HSI) is a potential driver of Influenza A virus (IAV) prevalence and subtype diversity in mallards.

Immunogenicity of Calvenza-03 EIV/EHV^® Vaccine in Horses: Comparative In Vivo Study

Vaccines, 2021
Equine influenza (EI) is a highly contagious acute respiratory disease of equines that is caused mainly by the H3N8 subtype of influenza A virus. Vaccinating horses against EI is the most effective strategy to prevent the infection.

Genetically Diverse Low Pathogenicity Avian Influenza A Virus Subtypes Co-Circulate among Poultry in Bangladesh. [PDF]

PLoS ONE, 2016
Influenza virus surveillance, poultry outbreak investigations and genomic sequencing were assessed to understand the ecology and evolution of low pathogenicity avian influenza (LPAI) A viruses in Bangladesh from 2007 to 2013.

Toward Predicting Pandemic Potential: A Comparative Analysis of Virus‐Host Interactions Between Diverse Influenza A Viruses and the Human Innate Immune System

PROTEOMICS, EarlyView.
ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...
