Figure 2From: Heterogeneous pathological outcomes after experimental pH1N1 influenza infection in ferrets correlate with viral replication and host immune responses in the lungRelation between histopathological score and quantification of viral antigen in pH1N1-infected ferrets. (A) Linear regression shows the correlation between IAV antigen quantification and histopathological scores at 4 dpi, independently of viral strains (*p value < 0.05). (B) Relation between viral load measured by RT-PCR and histopathological score; GEC of plasmid per gram of lung tissue. (C) Immunohistochemical cell quantification of IAV-positive cells in ferret lungs segregated by histopathological score; Results express the mean cell counts with SEM (20× objective field).Back to article page
