antibodies to h5 subtype avian influenza virus and japanese encephalitis virus in northern pintails (anas acuta) sampled in japan.blood samples from 105 northern pintails (anas acuta) captured on hokkaido, japan were tested for antibodies to avian influenza virus (aiv), japanese encephalitis virus (jev), and west nile virus (wnv) to assess possible involvement of this species in the spread of economically important and potentially zoonotic pathogens. antibodies to aiv were detected in 64 of 105 samples (61%). of the 64 positives, 95% and 81% inhibited agglutination of two different h5 aiv antigens (h5n1 and h5n9), respecti ...201324059097
antibodies to flaviviruses in wild ducks captured in hokkaido, japan: risk assessment of invasive flaviviruses.recently, the distribution of japanese encephalitis virus (jev) and west nile virus (wnv) has expanded into new territories. the invasion of wnv into japan is of great concern. the migration of birds is suggested to be involved in the expanded distribution of these flaviviruses. in this study, 92 wild ducks--20 anas poecilorhyncha (migratory breeders), 50 anas platyrhynchos (undetermined), 16 anas acuta (winter visitors), and 6 anas penelope (winter visitors)--were captured in autumn of 2005 and ...200919514809
