Influenza B virus inoculation caused pathology in the nasal turbinates, trachea and lungs of ferrets. Nasal turbinates (a, d, g, j, m, p), trachea (b, e, h, k, n, q), and lungs (c, f, i, l, o, r) were collected at 2, 4 and 6 days post inoculation (DPI) from animals inoculated with either Yamagata strain B/Guangzhou/12/2016 or Victoria strain B/Guangzhou/0215/2012 and stained with hematoxylin and eosin. Images were examined at magnification of × 200
