Figure 6. DAS181 inhibits pandemic IFV A(H1N1) viral replication in mice.
BALB/c mice were inoculated with the pandemic influenza A(H1N1) virus A/Mexico/4108/2009 (1000 MID50/mouse, i.n.). The mice were treated with PBS or DAS181 (0.3, 0.6, or 1 mg/kg) q.d.x5, beginning 6 hours post-infection. Lungs were harvested on day 3 and day 6 p.i.. Viral titer in lung homogenate was determined by standard plaque assay on MDCK cells. Values represent mean±SEM viral titer amongst 3 mice per group/day. PFU = plaque forming units. No virus was detectable on day 6 in the DAS181 1.0 mg/kg treatment group. Statistical significance from PBS treatment determined by ANOVA with Bonferroni post-test, * = p<0.05, ** = p<0.01, *** = p<0.001. The limit of detection is 100 PFU/ml.
