Evidence of Infection among Ferrets exposed to high levels of nebulized NC99.

a<p>For exposures to ferrets 2-C and 2-D, the diffusion dryer was inserted into the line exiting the Collison generator, reducing the humidity at the end of the hour nebulization.</p>b<p>Calculation of inhaled virus based on measured viral RNA in aerosol inhaled during 60 min of aerosol exposure.</p>c<p>Nasal wash was collected on day 2 post exposure (pe) in Exp 1, and daily in Exp 2; culture results are reported for the entire collection as FFU/mL; viral RNA is the peak titer on day 3 pe and is reported as GEq/collection.
