FIG 6.

Amentoflavone protects mice from SS2 infection. Mice were infected with SS2 by intraperitoneal injections and treated with 100 mg/kg of amentoflavone or DMSO as a control. The bacterial burden was determined from the sacrificed mice at 48 h after infection. (A) Survival analysis of infected or uninfected mice treated with amentoflavone over a 96-h period. (B) Bacterial burdens in the livers and spleens of the infected mice. The results shown are representative of three independent experiments. **, P < 0.01.
