Pathogenicity of three genetically distinct and highly pathogenic Egyptian H5N8 avian influenza viruses in chickens

Poultry Science, 2022
: In late 2016, Egypt encountered multiple cases of the highly pathogenic avian influenza (HPAI) virus of the H5N8 subtype. In a previous study, three distinct genotypes, including A/common-coot/Egypt/CA285/2016 (H5N8) (CA285), A/duck/Egypt/SS19/2017 ...

Impact of HIV-1 subtype and antiretroviral therapy on protease and reverse transcriptase genotype: Results of a global collaboration [PDF]

, 2005
Background The genetic differences among HIV-1 subtypes may be critical to clinical management and drug resistance surveillance as antiretroviral treatment is expanded to regions of the world where diverse non-subtype-B viruses predominate.Methods and ...

Biological Characterizations of H5Nx Avian Influenza Viruses Embodying Different Neuraminidases

Frontiers in Microbiology, 2017
The H5 subtype virus of Highly Pathogenic Avian Influenza Virus has caused huge economic losses to the poultry industry and is a threat to human health. Until 2010, H5N1 subtype virus was the major genotype in China.

From sporadic to global: The changing face of H5N8

, 2015
The H5N8 influenza subtype is a relatively new highly pathogenic avian influenza. Until the recent Korean outbreak of H5N8 the viral subtype had only been detected sporadically.

Genetic Characterization of Highly Pathogenic Avian Influenza A(H5N8) Virus in Pakistani Live Bird Markets Reveals Rapid Diversification of Clade 2.3.4.4b Viruses

Viruses, 2021
The highly pathogenic (HPAI) avian influenza A(H5N1) viruses have undergone reassortment with multiple non-N1-subtype neuraminidase genes since 2008, leading to the emergence of H5Nx viruses.

Evolutionary Dynamics of H5 Highly Pathogenic Avian Influenza Viruses (Clade 2.3.4.4B) Circulating in Bulgaria in 2019–2021

Viruses, 2021
The first detection of a Highly Pathogenic Avian Influenza (HPAI) H5N8 virus in Bulgaria dates back to December 2016. Since then, many outbreaks caused by HPAI H5 viruses from clade 2.3.4.4B have been reported in both domestic and wild birds in different

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, Volume 225, Issue 1, September 2026.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Some Exposure for Influenza Hemagglutinin Interface Antibodies

Immunological Reviews, Volume 342, Issue 1, September 2026.
ABSTRACT Influenza viruses are a constant threat to human health. Current vaccines often confer low to moderate protection against infection with seasonal viruses and little‐to‐no protection against pandemic viruses. Improved vaccines are needed. These vaccines will need to reliably elicit antibodies to conserved sites that are broadly protective.

Morphological Differences of Pancreatic Lesions in Mute Swans and Hens Naturally Infected with Highly Pathogenic Avian Influenza Virus H5N8

Acta Veterinaria, 2018
During the epizootic of highly pathogenic avian influenza subtype H5N8 in Serbia in the winter of 2016-2017, the highest percent of mortality due to this infection was recorded in mute swans (Cygnus olor).
