Fig. 3From: Comparison of the virulence of three H3N2 canine influenza virus isolates from Korea and China in mouse and Guinea pig modelsHistopathological lesions in lung samples from mice infected with the four virus strains at 7 dpi. Histopathological findings in the lungs of mice at 7 days post-inoculation with 106 EID50/mL of the JS/10, KR/07, MV/12 and CA/09 strains. All inoculated groups demonstrated histopathological pneumonic lesions. (A) – (E) are representative microscopic images of the histopathological pneumonic lesions from each group (X100). (A) JS/10 and (B) KR/07 resulted in mild lymphocyte infiltration and congestion. (C) MV/12 and (D) CA/09 resulted in mild lymphocyte infiltration and moderate congestion and hemorrhaging. (E) Lung tissue in the normal stateBack to article page
