Source: Viruses, AbstractInfluenza A viruses (IAVs) circulate among different species and have the potential to cause significant pandemics in humans. This study focuses on reassortment events in the H5N8 subtype of IAV, which poses a serious threat to public health due to its high pathogenicity in birds and potential for cross-species transmission. We…

Complex Evolutionary #Dynamics of #H5N8 #Influenza A Viruses Revealed by Comprehensive #Reassortment Analysis https://www.mdpi.com/1999-4915/16/9/1405

This detailed case study of specific H5N8 viruses revealed previously undescribed reassortment events, highlighting the complex evolutionary history and potential pandemic threat of H5N8 IAVs.

Novel #Genotype of #HA Clade 2.3.4.4b #H5N8 Subtype High Pathogenicity Avian #Influenza Virus Emerged at a Wintering Site of Migratory #Birds in #Japan, 2021/22 Winter https://pubmed.ncbi.nlm.nih.gov/38787232/?utm_source=Feedly&utm_medium=rss&utm_campaign=None&utm_content=1LGAx__djGAJ9poBzWGqPtjEbBDtz4ipSRRPUplmgHEyyF_Ihj&fc=None&ff=20240524150849&v=2.18.0.post9+e462414

Our results directly demonstrate the emergence of a novel genotype of H5N8 HPAIV through gene reassortment at a wintering site.

Caught Right on the Spot: #Isolation and Characterization of Clade 2.3.4.4b #H5N8 High Pathogenicity Avian #Influenza Virus from a Common #Pochard (Aythya ferina) Being Attacked by a Peregrine #Falcon (Falco peregrinus) https://pubmed.ncbi.nlm.nih.gov/38687111/?utm_source=Feedly&utm_medium=rss&utm_campaign=None&utm_content=1LGAx__djGAJ9poBzWGqPtjEbBDtz4ipSRRPUplmgHEyyF_Ihj&fc=None&ff=20240430181504&v=2.18.0.post9+e462414

These findings provide direct evidence supporting the possibility of HPAI transmission from infected waterfowl to predators.

By leveraging an integrated non-linear regression model, we quantitatively determined the influence of these markers on growth, adaptation, and RNA expression in mammalian hosts. Furthermore, our findings revealed that the interplay of these markers can lead to synergistic, additive, or antagonistic effects when combined.

The genetic diversity and ongoing evolution of these viruses highlight the need for vigilant surveillance and adaptive control measures. Recognizing the potential spillover to human populations, a One Health approach is essential to mitigate the evolving threats posed by avian influenza.

"Nun also – während einer Pandemie! – fröhlich weiter Geflügel durch die Weltgeschichte zu karren, das ist ein bisschen so wie den zweiten Gifttrank zu bestellen, ohne den ersten bis zum Ende ausgetrunken zu haben."

BREAKING: For the first time it is observed that #H5N8 (brid flue) infected humans, thanks to humans disgusting practice of intensive mass animal farming.

Capitalist driven exploitation of non-human animals will continue to cause many different crisis.
Pandemics and climate crisis only the most known.

It must stop.

If you don't care for the non-human animals, maybe at least care for yourself and the people around you. If we continue to mistreat non-human animals as we do currently, it's always only a matter of time until the next pandemic knocks on the door.

Animal liberation & human liberation!
