Genetic Characterization of Avian Influenza A(H5N6) Virus Clade 2.3.4.4, Russia, 2018

Emerging Infectious Diseases, 2019
Timely identification of pandemic influenza threats depends on monitoring for highly pathogenic avian influenza viruses. We isolated highly pathogenic avian influenza A(H5N6) virus clade 2.3.4.4, genotype G1.1, in samples from a bird in southwest Russia.

Dairy cows inoculated with highly pathogenic avian influenza virus H5N1. [PDF]

Nature
Abstract Highly pathogenic avian influenza (HPAI) H5N1 haemagglutinin clade 2.3.4.4b was detected in the USA in 2021. These HPAI viruses caused mortality events in poultry, wild birds and wild mammals. On 25 March 2024, HPAI H5N1 clade 2.3.4.4b was confirmed in a dairy cow in Texas in response to a multistate investigation into milk ...

Emergence of a Highly Pathogenic Avian Influenza Virus from a Low-Pathogenic Progenitor [PDF]

Journal of Virology, 2014
ABSTRACT Avian influenza (AI) viruses of the H7 subtype have the potential to evolve into highly pathogenic (HP) viruses that represent a major economic problem for the poultry industry and a threat to global health. However, the emergence of HPAI viruses from low-pathogenic (LPAI) progenitor viruses currently is poorly understood.

Molecular Study on The Pathogenicity of Avian Influenza Virus

Indonesian Journal of Biotechnology, 2006
Highly pathogenic avian influenza virus (HPAI) differ from Low pathogenic avian influenza virus (LPAI) based on multiple basic amino acid motif of the carboxylterminus of HA1, especially arginine and lysine.

Chlorine Inactivation of Highly Pathogenic Avian Influenza Virus (H5N1)

Emerging Infectious Diseases, 2007
To determine resistance of highly pathogenic avian influenza (H5N1) virus to chlorination, we exposed allantoic fluid containing 2 virus strains to chlorinated buffer at pH 7 and 8, at 5 degrees C. Free chlorine concentrations typically used in drinking water treatment are sufficient to inactivate the virus by >3 orders of magnitude.

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.

First case of highly pathogenic H5N1 avian influenza virus in Spain [PDF]

BMC Veterinary Research, 2008
The H5N1 strain of avian influenza virus has been involved in severe mortality in domestic poultry, and has also been found in different species of wildlife in Europe. The Basque Country avian influenza surveillance program began sample collection and processing the fall of 2005.Here we report the first confirmation of the presence of highly pathogenic
