From: Limited efficacy of West Nile virus vaccines in large falcons (Falco spp.)
WNV antigen dectection by immunohistochemistry in different tissues of falcons after virus challenge. A: Brain/Telencephalon (region lateral of the lateral ventricle) of a challenged falcon (F6) included in a previously published study [12] at day 10 post infection. B: Spleen of a bird at day 8 post infection without vaccination (F51). Antigen was detected in necrotic material of follicle arteries. C: Myocard of a falcon vaccinated twice with the inactivated vaccine (F17, necropsied at day 9 post infection). Antigen staining in cardiocytes (arrows). All results were obtained using the monoclonal antibody 15R4 (kindly provided by Petra Emmerich, Bernhard-Nocht Institute, Hamburg, Germany).
