Demonstration of Usutu virus antigen 3 days postinfection. Immunohistochemical (IHC) tests were performed by using a polyclonal antibody to West Nile virus, which cross-reacts with Usutu virus. A) Vero control; B) Vero infected; C) CR (feline) control; D) CR infected; E) goose embryo fibroblast (GEF) control; F) GEF infected; A,B) bar = 50 μm; C–F) bar = 100 μm. †3 days postinfection (p.i.), IHC staining.
