Evaluation of the kinetics of anti-NP and anti-HA antibody after infection of Pekin ducks with low pathogenic avian influenza virus
circulation of notifiable low pathogenic avian influenza (LPAI) viruses in commercial poultry holdings. Commercial multispecies nucleoprotein (NP) enzyme-linked immunosorbent assays (ELISA s) have been ...
Impact of Age, Season, and Flowing vs. Stagnant Water Habitat on Avian Influenza Prevalence in Mute Swan (Cygnus olor) in Belgium.
factors. Using a nucleoprotein (NP)-based ELISA, a global antibody prevalence of 35% has been found and was characterized by two peaks in the winter and the summer that might be indicative of a greater LPAI ...
Multiyear Serological Surveillance of Notifiable Influenza A Viruses in Belgian Poultry: A Retrospective Analysis.
Belgium, this serological monitoring is a combination of a stratified and a risk-based approach and is applied to commercial holdings with more than 200 birds. Moreover, a competitive nucleoprotein (NP) ...
Persistence of the protective immunity and kinetics of the isotype specific antibody response against the viral nucleocapsid protein after experimental Schmallenberg virus infection of sheep.
euthanasia. The presence of SBV RNA in serum and organs was measured with quantitative real-time PCR. The appearance and persistence of neutralizing and SBV nucleoprotein (N) isotype specific antibodies was ...
Evaluation of four enzyme-linked immunosorbent assays for the serologic survey of avian influenza in wild bird species.
Pekin ducks. This study shows that some care must be taken before using nucleoprotein ELISA s for the testing of sera from wild birds and that more reliable validation studies should be considered before ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
against the hemagglutinin, the neuraminidase, the nucleoprotein, and the M2 e after infections with LPNAI viruses isolated from waterfowl or already adapted to chicken. Overall, the immune responses against ...
Electron tomography of negatively stained complex viruses: application in their diagnosis.
nucleoprotein strand of Newcastle disease virus. For both viruses, deformation and flattening were observed. CONCLUSION: The combination of negative staining of complex viruses with electron tomographic analysis, ...
