Figure 3

In vivo activity of Bac7(1-35). Survival curves (A) and viable bacterial counts in liver and spleen homogenates (B) of mice infected with S. enterica after treatment via i.p. with Bac7(1-35) are shown. CBA/Ca mice were infected via i.p. with S. enterica ATCC 14028 (102 CFU/mouse) and Bac7(1-35) at 30 mg/kg was immediately injected via i.p. after bacterial challenge (dotted line). Control mice were given 0.2 ml of PBS (continuous line). Mice were monitored for survival over a 60-day period after infection. *p < 0.05 treated vs untreated mice. Three days after bacterial infection, untreated (squares) and peptide-treated (triangles) mice were killed, and liver (full symbols) and spleen (empty symbols) homogenates were prepared as described in section Methods. Results are expressed as number of CFU/g organ; bars represent the mean value for each group.
