Dynamics of influenza A virus infection of four naïve mallards each exposed to artificially pool water containing 102, 103 or 104 TCID50 L−1 of HPAIV H5N8. (1) Qualitative results; percentage of mallards excreting viral RNA orally, cloacally, and of RNA adhering to the breast plumage (percentage RT-qPCRs-positive mallards per group) are shown. (2) Quantitative results of viral RNA excretion compared between exposure groups 102 (open circle), 103 (filled circle), and 104 (open triangle) in (a) oral, (b) cloacal and (c) plumage swabs.
