(A) Microscopic lesions in a lung characterized by interstitial infiltration of inflammatory cells (arrows), mild bronchiolar changes with degeneration and disorganization of epithelial cells (arrowhead) and increased numbers of macrophages in bronchiolar lumens and alveoli. HE, bar = 50 μm. (B) Positive immunostaining for influenza A viral antigen was detected in scattered bronchiolar epithelial cells. IHC, bar = 50 μm.
