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.

Multiple Introductions of Influenza A(H5N8) Virus into Poultry, Egypt, 2017 [PDF]

Emerging Infectious Diseases, 2018
After high mortality rates among commercial poultry were reported in Egypt in 2017, we genetically characterized 4 distinct influenza A(H5N8) viruses isolated from poultry. Full-genome analysis indicated separate introductions of H5N8 clade 2.3.4.4 reassortants from Europe and Asia into Egypt, which poses a serious threat for poultry and humans.

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 ...

Pathogenicity of H5N8 virus in chickens from Korea in 2014

Journal of Veterinary Science, 2015
In 2014, two genetically distinct H5N8 highly pathogenic avian influenza (HPAI) viruses were isolated from poultry and wild birds in Korea. The intravenous pathogenicity indices for the two representative viruses were both 3.0. Mortality of chickens intranasally inoculated with the two H5N8 viruses was 100% with a mean death times of 2.5 and 4.5 days ...
