Isolation and Genetic Characterization of Influenza A (Subtype H5N1) Virus from Crows in India [PDF]

Advances in Animal and Veterinary Sciences, 2014
We isolated two influenza A (subtype H5N1) viruses from crows in India, in 2011 and 2012. Nucleotide sequence of all eight genome segments of both the viruses (A/crow/India/ 11TI07/2011 and A/crow/India/01TR01/2012) was determined and used for analysis. The two iso - lates shared >99% nucleotide sequence identity in all the eight genes.

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

Pathogenicity of Highly Pathogenic Avian Influenza Virus (H5N1) in Adult Mute Swans

Emerging Infectious Diseases, 2008
Adult, healthy mute swans were experimentally infected with highly pathogenic avian influenza virus A/Cygnus cygnus/Germany/R65/2006 subtype H5N1. Immunologically naive birds died, whereas animals with preexisting, naturally acquired avian influenza ...

Purification and production of monospecific antibody to the hemagglutinin from Subtype H5N1 influenza virus

Jurnal Ilmu Ternak dan Veteriner, 2012
The purpose of this study was to purify the hemagglutinin from H5N1 virus and to generate monospecific antibody appropriate for production of sensitive and specific immunoassay for H5N1 avian influenza. For this purpose, a local isolate H5N1 virus (A/Ck/West Java/Hamd/2006) was propagated in chicken embryos. The viral pellet was dissolved in a Triton-X-

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,

Swine influenza A virus subtype H1N2 in Sweden [PDF]

, 2012
The influenza A virus subtypes H1N1, H1N2 and H3N2 are prevalent in pig populations worldwide. All scientific data point towards swine as the key host species when new human influenza pandemics arise.

Statins for the prevention of cardiovascular events associated with avian influenza: the COVID-19 pandemic as a reference

Annals of Medicine
There is growing concern that the severe respiratory disease in birds (avian influenza or ‘bird flu’) caused by the H5N1 influenza virus, might potentially spread more widely to humans and cause a pandemic.

Between‐species contagion drives HPAI transmission and mass mortality in seabirds

Journal of Animal Ecology, Volume 95, Issue 8, Page 1488-1503, August 2026.
Modelling the unprecedented avian panzootic caused by High‐Pathogenicity Avian Influenza (HPAI) across the Northeast Atlantic gannet breeding metapopulation, we estimated 28% (95% CI: 21%–34%) HPAI‐related mortality. Large‐scale outbreak initiation was best explained by external infection sources, most likely, other seabird species.

Influenza H5N1 virus infection of polarized human alveolar epithelial cells and lung microvascular endothelial cells

Respiratory Research, 2009
Background Highly pathogenic avian influenza (HPAI) H5N1 virus is entrenched in poultry in Asia and Africa and continues to infect humans zoonotically causing acute respiratory disease syndrome and death.
