Histological analysis of pneumonia and distribution of viral antigens in immunocompetent macaques infected with VN3040.
Tissues were collected from macaques injected with control antibodies (C2) (A, C, E) or MAb ch61 (T1) (B, D, F) on day 7 after virus infection. A, B: low magnification of hematoxylin and eosin (H & E) staining (bar: 100 µm). C, D: high magnification of H & E staining (bar: 50 µm). E, F: sections stained with anti-NP serum (bar: 50 µm).
