Phylogenetic Analysis of Hemagglutinin Gene of H9N2 Avian Influenza Viruses Isolated from Chicken in Iran in 2010-2011: Emerging of a New Subgroup
Background and Aims: Hemagglutinin (HA) protein of Avian Influenza (AI) plays an essential role in the virus pathogenicity. AI H9N2 subtype causes significant economic loss in broiler and layer in poultry farms in Iran. AI viruses have a great involvement in evolutionary changes at nucleotide and amino acid levels and vaccines could induce faster rates of such changes. Up-dated understanding of...
متن کاملSeroprevalence of Hepatitis A and Hepatitis B Viruses Among Blood Donors in North of Iran
Background and Objective: Hepatitis A virus (HAV) and hepatitis E virus (HEV) are both transmitted by the fecal-oral route and are known as leading causes of acute viral hepatitis in the world, especially in developing countries. There is a lack of updated data on HAV and HEV seroprevalence in the north of Iran. This study aimed to determine the seroprevalence of HAV and HEV among blood donors ...
