H&E staining of lungs of mice infected with (A) 10 TCID50 infected BALB/c mice, (B) 100 TCID50, or (C) 1000 TCID50, at five days post-infection as compared to mice infected with (D) 10 TCID50, (E) 100 TCID50, (F) and 1000 TCID50 at seven days post-infection or with the lungs of (G) 10 TCID50, (H) 100 TCID50, and (I) 1000 TCID50 infected mice at 12 days post-infection as compared to uninfected controls (J). One representative animal of five is shown for each group.
