17. Seroprevalence survey of H9N2 avian influenza virus in backyard chickens around the Caspian Sea in Iran
Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent presented low pathogenicity, and was subtyped as an H9N2 avian influenza virus. Backyard chickens can play an important role in the epidemiology of H9N2 avian influenza virus infection. Close contact of backyard chickens with migratory birds, especially

21. The economic impact of potential avian flu outbreaks in Brazil: a general equilibrium model analysis / Avaliação do impacto econômico de possíveis surtos da gripe aviária no Brasil: uma análise de equilíbrio geral computável
In the past few years, the bird flue virus H5N1 spread rapidly through various countries and continents, causing great economic and human losses. There is also the possibility of the disease arriving in Brazil, which would have a substantial impact on the countrys economy, particularly on its poultry sector. The present study addresses the lack of estimates

24. Nucleoprotein and membrane protein genes are associated with restriction of replication of influenza A/Mallard/NY/78 virus and its reassortants in squirrel monkey respiratory tract.
An avian influenza A virus, A/Mallard/NY/6750/78(H2N2), was restricted in in replication in the respiratory tract of squirrel monkeys. Avian-human influenza A reassortant viruses possessing the six RNA segments coding for nonsurface proteins (i.e., internal genes) of this avian virus were as restricted in replication in squirrel monkeys as their avian influe
