FIG. 3.

Acute FV infection in mice deficient for IFN-β or IFNAR. C57BL/6 wild-type or knockout mice that lack IFN-β or IFN type I receptor (IFNAR) were infected with FV. Viral loads were measured at 11 days after infection in the spleen (A) and in the blood (B). The results for the knockout mice were compared with those obtained for wild-type mice. The mean value for each group is indicated by a bar. Differences between the group of infected wild-type mice and the groups of knockout mice were analyzed by using Dunnett's multiple-comparison correction test for comparing a control group to several experimental groups. Statistically significant differences between the groups are indicated.
