Avian Influenza H5N1 in Egypt: What we Know and What we have to Know?
...demic outbreaks of avian influenza viruses (AIV) of subtype H5N1 in poultry since 2008. Since then, these viruses continue to evolve. In 2006-2008, outbreaks were reported mostly during the winter season, but in 2009-2012 they occurred year round. H5N1 AIV succeeded in infecting not only domesticated birds but also many other avian species and mammals. Infections of humans were accompanied by mutations in the hemagglutinin (HA) protein which improved the bindi...

It was found that, all the inoculated isolates caused high mortalities up to 100% for the embryos 24-48hrs post inoculation and gave very strong RBCs agglutination. The haemagglutination positive samples were identified and subtyped antigenically by serological tests using Haemagglutination inhibition test (HI) using standard Al antisera and genetically by RT-PCR using sp...
