avian influenza viruses in wild land birds in northern vietnam.given a paucity of data on the occurrence of avian influenza viruses (aivs) in wild passerines and other small terrestrial species in southeast asia and the importance of highly pathogenic asian-strain h5n1 outbreaks in humans and domestic poultry in these areas, we focused on surveillance for influenza a viral nucleic acids and antibodies for aivs in wild-caught birds in northern vietnam. four of 197 serum samples collected in 2007 from black-crested bulbul (pycnonotus melanicterus), crow-bille ...201222247391
single- and multiple-clade influenza a h5n1 vaccines induce cross protection in ferrets.the rapid evolution, genetic diversity, broad host range, and increasing human infection with avian influenza a (h5n1) viruses highlight the need for an efficacious cross-clade vaccine. using the ferret model, we compared induction of cross-reactive immunity and protective efficacy of three single-clade h5n1 vaccines and a novel multiple-clade h5n1 vaccine, with and without mf59 adjuvant. reverse genetics (rg) was used to generate vaccine viruses containing the hemagglutinin (ha) and neuraminida ...200919406182
