a
Lung viral titers are expressed as log10 TCID50/g of lung tissue taken from 2 ferrets from each group 4 days after H1N1pdm virus challenge.
b
Morbidity was assessed by monitoring weight loss after H1N1pdm virus challenge. Results are expressed as mean percentages of weight loss at 4 and 7 days postchallenge.
c
<, below assay detection limit.
