The highly pathogenic avian influenza virus A (HPAI) H5N1 was first identified in a farmed goose 1996 from China. High viruses cause severe disease poultry and represent smaller proportion of influenzas). In 2008, the H5Nx acquired function to reassort its neuraminidase (N) created 2.3.4.4 clade. Initial outbreaks 2.3.4.4b began H5N8 H5N6 2016. However, 2020, whole genome sequencing (WGS) condu...

This study's main objective was to update avian influenza (AI) epidemiological situation, including molecular characterization reassortment analysis and genotyping of circulating AI virus (AIV) subtypes in Egyptian poultry farms between 2017 2019. As a necessity for such work, improved diagnostic tools were developed AIV detection. Subtype H9N2 infections detected 27 out 39 examined frequently ...
