Fig. 3

Representative IF staining (red) of rickettsiae (b, c) and Ebola virus (e, f) in livers from archived mouse samples of fatal SFGR and Ebola virus infection. Mock infection mouse samples processed in ABSL3 (a) and ABSL4 (d) were employed as mock controls. Nuclei were counter-stained with DAPI (blue). Scale bars, 20 µm (a–c, f) and 50 µm (d, e).
