Duck STING Mediates Innate Immune Response Induced by H5N8 Subtype Avian Influenza Viruses

Acta Scientiae Veterinariae
Background: The H5N8 highly pathogenic avian influenza virus (HPAIV) poses a significant threat to global poultry and public health due to its high mortality rate and potential for cross-species transmission. As natural H5N8 hosts, Anatidae (e.g., ducks)

Genetic features of avian influenza (A/H5N8) clade 2.3.4.4b isolated from quail in Egypt [PDF]

Virus Research
Several genotypes of the highly pathogenic avian influenza (HPAI) virus H5N8 subtype within clade 2.3.4.4b continue to circulate in different species of domestic birds across Egypt. It is believed that quail contribute to virus replication and adaptation

Estimation of the Basic Reproduction Numbers of the Subtypes H5N1, H5N8, and H5N6 During the Highly Pathogenic Avian Influenza Epidemic Spread Between Farms

Frontiers in Veterinary Science, 2021
It is important to understand pathogen transmissibility in a population to establish an effective disease prevention policy. The basic reproduction number (R0) is an epidemiologic parameter for understanding the characterization of disease and its ...

Genetic characterization of highly pathogenic avian influenza A (H5N8) virus isolated from domestic geese in Iraq, 2018

BMC Veterinary Research, 2021
Background Influenza viruses are a continuous threat to avian and mammalian species, causing epidemics and pandemics. After the circulation of H5N1 in 2006, 2015, and 2016 in Iraq, an H5N8 influenza virus emerged in domestic geese in Sulaymaniyah ...

Sub-Saharan Africa and Eurasia Ancestry of Reassortant Highly Pathogenic Avian Influenza A(H5N8) Virus, Europe, December 2019

Emerging Infectious Diseases, 2020
We report detection of a highly pathogenic avian influenza A(H5N8) clade 2.3.4.4b virus in Europe. This virus was generated by reassortment between H5N8 subtype virus from sub-Saharan Africa and low pathogenicity avian influenza viruses from Eurasia.
