At 0, 1, 2, 5, 14, and 28 dpi, plasma and PBMCs were collected.
At 7, 21, and 35 dpi, 3 pigs from each group were terminated, and their plasma, PBMCs, bronchoalveolar lavage fluid, and lung tissue samples were collected.
Pigs for blood collection at the indicated time point.
Pigs terminated at the indicated time point.
Pig 12 died before 7 dpi.
