Extended Data Figure 2: Replication of α2,3 H1N1pdm virus in ferret respiratory tract.
From: The soft palate is an important site of adaptation for transmissible influenza viruses
a–f, We confirmed that the α2,3 H1N1pdm virus replicated to high titres on days 1, 3, 5 and 7 in different parts of the ferret respiratory tract. Each tissue homogenate is highlighted with a dashed circle; the grey circles represent washes. Each point represents a single animal. The horizontal black line indicates the mean viral titre on a given day.
