Influenza A Virus H5N1 Subtype: Resurgent Interspecies and Intercontinental Transmission, and a New Host [PDF]

Pathogens
It has been more than 25 years since the avian influenza A virus (IAV) H5N1 subtype emerged in humans in 1997. Since then, this virus has become endemic in poultry and wild birds and has been causing sporadic infections in humans.

Determinants of Antiviral Effectiveness in Influenza Virus A Subtype H5N1 [PDF]

Journal of Infectious Diseases, 2012
Oseltamivir is widely used as treatment for influenza virus A subtype H5N1 (hereafter, "H5N1") infection but, like any intervention, is not always effective.We used Avian Influenza Registry data from 10 countries to examine the risk of death in 215 patients with confirmed H5N1 infection who were treated with oseltamivir, according to viral clade, age ...

Systemic infection of avian influenza A virus H5N1 subtype in humans

Human Pathology, 2009
The viral dissemination in a patient with avian influenza A subtype H5N1 infection was retrospectively studied by the immunohistochemical localization of viral nucleoprotein antigen. The pathology was marked by diffuse alveolar damage, lymphoid depletion, and reactive hemophagocytic syndrome.

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

Development of ssDNA Aptamers for Diagnosis and Inhibition of the Highly Pathogenic Avian Influenza Virus Subtype H5N1 [PDF]

Biomolecules, 2020
Avian influenza (AI) has severely affected the poultry industry worldwide and has caused the deaths of millions of birds. Highly pathogenic avian influenza virus is characterized by high mortality and the ability to transmit from birds to humans. Early diagnosis is difficult because of the variation in pathogenicity and the genetic diversity between ...

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 ...

A Latex Agglutination Test for the Rapid Detection of Avian Influenza Virus Subtype H5N1 and its Clinical Application [PDF]

Journal of Veterinary Diagnostic Investigation, 2007
A rapid and simple latex agglutination test (LAT) for the detection of avian influenza virus (AIV) subtype H5N1 in chicken allantoic fluids, tracheal swabs, and tissues was developed. Monoclonal antibodies against the hemagglutinin glycoprotein of H5N1 were covalently coupled onto the surface of carboxylated latex bead using a water-soluble ...

Epidemiology of the Influenza A Virus H5N1 Subtype and Memory of Immunity to the H2N2 Subtype [PDF]

mBio, 2012
In their recent paper, Peter Palese and Taia T. Wang proposed a hypothesis to explain how an older circulating subtype of influenza A virus is replaced with a novel subtype (1). They and others also published experimental evidence supporting their hypothesis on the extinction of seasonal H1N1 viruses by the 2009 pandemic H1N1 viruses (2). Although they

Serological survey for avian influenza virus infection of backyard poultry and poultry workers in Baghdad and Basrah provinces, Iraq [PDF]

Bulgarian Journal of Veterinary Medicine, 2020
The aim of this study was to determine the prevalence of avian influenza virus (AIV) subtype H5N1 among backyard birds and poultry workers. The study included backyard birds (chickens and ducks) in rural areas of Baghdad and Basrah provinces, Iraq. Rural
