Proinflammatory cytokine responses induced by influenza A (H5N1) viruses in primary human alveolar and bronchial epithelial cells

Respiratory Research, 2005
Background Fatal human respiratory disease associated with influenza A subtype H5N1 has been documented in Hong Kong, and more recently in Vietnam, Thailand and Cambodia. We previously demonstrated that patients with H5N1 disease had unusually high serum

H5N1 Clade 2.3.4.4b Infections in Domestic Cats During an Avian Influenza Outbreak in Italy: Implications for One Health Surveillance

Influenza and Other Respiratory Viruses, Volume 20, Issue 9, September 2026.
ABSTRACT Background H5Nx goose/Guangdong (Gs/GD) lineage highly pathogenic avian influenza (HPAI) viruses pose a significant public health threat due to their global spread, mutation accumulation, and expanding host range. The descendant clade 2.3.4.4b has been causing widespread infections in birds and increasing spillover events in mammals.

CD4+ T‐cell responses directed towards A/H5N1‐derived haemagglutinin peptides increase in patients with seasonal influenza A virus infection

Clinical &Translational Immunology, Volume 15, Issue 8, 2026.
Abstract Objectives Recent outbreak of influenza A/H5N1 viral infections in birds and mammals worldwide prompted renewed concerns over an emerging H5N1‐related influenza pandemic in the generally immunologically‐naive global population. Cross‐reactive CD4+ T cells between A/H1N1 and A/H5N1 subtypes targeting internal and surface influenza proteins have

First Case of Highly Pathogenic Avian Influenza H5N1 in Montenegro

Acta Veterinaria
Avian influenza, commonly known as bird flu, is a highly infectious viral disease that affects birds, including wild water birds and poultry. The emergence and spread of highly pathogenic avian influenza (HPAI) strains, such as H5N1, have raised concerns

Review of the Epizootic and Epidemic Situation regarding Highly Pathogenic Avian Influenza in Russia and Globally in 2025

Проблемы особо опасных инфекций
In 2025, high epizootic activity of highly pathogenic avian influenza virus (HPAIV) persisted globally, as evidenced by more than 7,000 outbreaks reported in poultry and wild birds across 75 countries, resulting in mortality or culling of birds exceeding

The Involvement of the Cryptococcal Yeast Kexin Protease in the Proteolytic Activation of the Uncleaved Influenza Virus Hemagglutinin Glycoprotein

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
A haemagglutinin mimetic fluorogenic peptide assay revealed that recombinant Cryptococcus neoformans Kex2p exhibits strong haemagglutinin‐cleaving activity, suggesting a possible role for cryptococcal proteases in influenza virus activation. ABSTRACT Infectious diseases typically involve a single pathogen harming its host. However, in clinical settings,

Control of a highly pathogenic H5N1 avian influenza outbreak in the GB poultry flock.

, 2007
The identification of H5N1 in domestic poultry in Europe has increased the risk of infection reaching most industrialized poultry populations. Here, using detailed data on the poultry population in Great Britain (GB), we show that currently planned ...

Timing of Influenza A(H5N1) in Poultry and Humans and Seasonal Influenza Activity Worldwide, 2004–2013

Emerging Infectious Diseases, 2015
Co-circulation of influenza A(H5N1) and seasonal influenza viruses among humans and animals could lead to co-infections, reassortment, and emergence of novel viruses with pandemic potential. We assessed the timing of subtype H5N1 outbreaks among poultry,
