Table 2 Characteristics of the experimental infection of ferrets with two different pH1N1 influenza viruses: viral inoculums, histopathological scores and pathological classifications

From: Heterogeneous pathological outcomes after experimental pH1N1 influenza infection in ferrets correlate with viral replication and host immune responses in the lung
