Highly Pathogenic Avian Influenza A(H5N8) Virus, Cameroon, 2017 [PDF]

Emerging Infectious Diseases, 2018
Highly pathogenic avian influenza A(H5N8) viruses of clade 2.3.4.4 spread into West Africa in late 2016 during the autumn bird migration. Genetic characterization of the complete genome of these viruses detected in wild and domestic birds in Cameroon in January 2017 demonstrated the occurrence of multiple virus introductions.

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 ...

Highly pathogenic avian influenza A subtype H5N8 [PDF]

EFSA Journal, 2014
Abstract Highly pathogenic avian influenza (HPAI) H5N8 outbreaks in poultry farms have been reported in Asia and Europe since January and November 2014, respectively. The entry of HPAI H5N8 into Europe and its subsequent spread within Europe are two separate events with possibly different transmission vectors.

Low Virulence and Lack of Airborne Transmission of the Dutch Highly Pathogenic Avian Influenza Virus H5N8 in Ferrets. [PDF]

PLoS ONE, 2015
Highly pathogenic avian influenza (HPAI) H5N8 viruses that emerged in poultry in East Asia spread to Europe and North America by late 2014. Here we show that the European HPAI H5N8 viruses differ from the Korean and Japanese HPAI H5N8 viruses by several ...

Avian Influenza H5N8 Outbreak in African Penguins (Spheniscus demersus), Namibia, 2019 [PDF]

Journal of Wildlife Diseases, 2020
In January 2019, high mortalities were reported among African Penguins (Spheniscus demersus) in a breeding colony on Halifax Island, Namibia, Africa. Analysis of samples by reverse transcription quantitative PCR indicated the presence of highly pathogenic avian influenza (HPAI) subtype H5N8.

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 ...

Complete analysis of the H5 hemagglutinin and N8 neuraminidase phylogenetic trees reveals that the H5N8 subtype has been produced by multiple reassortment events [PDF]

, 2016
The analysis of the complete H5 hemagglutinin and H8 neuraminidase phylogenetic trees presented in this paper shows that the H5N8 avian influenza has been generated by multiple reassortment events.

Comparative Virological and Pathogenic Characteristics of Avian Influenza H5N8 Viruses Detected in Wild Birds and Domestic Poultry in Egypt during the Winter of 2016/2017

Viruses, 2019
The surveillance and virological characterization of H5N8 avian influenza viruses are important in order to assess their zoonotic potential. The genetic analyses of the Egyptian H5N8 viruses isolated through active surveillance in wild birds and domestic
