Fig. 1: Electron micrographs of JUAV particles in mouse CNS cells.

Electron micrographs illustrating JUAV particles. A Negative staining of primary culture supernatant from mouse central nervous system (CNS) cells, highlighting viral particles. B Ultrathin sections of the mouse brain at 8 days post-infection (dpi), showing nonenveloped viral particles clustered in the cytoplasm. C and D Immunoelectron micrographs demonstrating immunocomplexes formed between the anti-JUAV antibody and viral particles (white arrows). These images are representative of three independent experiments.
