Fig. 3From: Elucidating the characteristics of Mx1 and resistance to influenza A virus subtype H1N1 in the newly developed KWM/Hym miceHistopathological lesions in the lung of inbred BALB/c and KWM/Hym mice. The BALB/c and KWM/Hym female mice (N = 6/group) were challenged intranasally with mouse-adapted A/WSN/1933 virus (H1N1, 1 × 105 pfu/mouse). Four days after infection, the lungs were collected, and hematoxylin and eosin staining was performed. The infected KWM/Hym mice showed mild alveolitis and loss of bronchiolar epithelium, significantly less than that of the infected BALB/c mice (scale bars = 100 μm)Back to article page
