IHC results of the lung. A Lung parenchyma was strongly positive against SARS-CoV-2 NP in IHC at 4 dpi. Counterstain with methyl green. Scale bars, 100 μm (n = 3 per group). B Bronchiolar epithelium showed strong positive against SARS-CoV-2 NP in IHC on 2 and 4 dpi. Counterstain with methyl green. Scale bars represent 100 μm. C Quantification of IHC positive area in lung against SARS-CoV-2 NP. Data are presented as means with SD. All infection groups showed higher positive areas than the control group (P < 0.01). The 4 dpi group showed more strong positive area compared to the control and other infection groups (P < 0.01). IHC positive areas in 12 and 16 dpi groups were lower compared to those in other infection groups (P < 0.01) (n = 3 per group).
