Replication of influenza virus in nasal turbinate and lung of inoculated mice.
Viral titers in the lungs (A,C) and nasal turbinate (B,D) harvested at 3 and 5dpi. Viral titers were determined by EID50 by using embryonated chicken eggs. Error bars represent standard errors of the mean (SEM), dotted line represents the limitation of the detection. *P < 0.05, **P < 0.01.
