Figure 3From: Activation of coagulation and tissue fibrin deposition in experimental influenza in ferrets Lendrum staining expressing fibrin (red) in lung tissue of a control ferret or 4 days after inoculation of different influenza viruses. No staining in a non-infected ferret (A), occasional intracappilairy staining of fibrin in ferrets inoculated with H3N2 (B) and pH1N1 (C), and multifocal intracapillary staining in ferrets inoculated with H5N1 (D). Panel E shows the results of a semi-quantitative scoring of fibrin deposition obtained by examining 25 images per slide.Back to article page
