Fig. 6From: Comparison of the virulence of three H3N2 canine influenza virus isolates from Korea and China in mouse and Guinea pig modelsGross lesions of lung samples from guinea pigs infected with the four virus strains in both the inoculation and contact groups. Guinea pigs were inoculated with 106 EID50/mL of the JS/10, KR/07, MV/12 and CA/09 strains. After 24 h on 1 dpi, additional naïve guinea pigs were placed into each virus group as the contact group. Pictures were taken of the gross lesions of the viral inoculation groups at 3 dpi for JS/10 (a), KR/07 (c), MV/12 (e) and CA/09 (G) and of the virus contact groups at 6 dpi (5 dpe) for JS/10 (b), KR/07 (d), MV/12 (f) and CA/09 (H). Macroscopic images of guinea pig lungs in the PBS negative control (I) were also takenBack to article page
