Lethal toxin-neutralizing antibodies (ED50). Sera from mice described in Fig. 1 were also measured for lethal toxin neutralization antibodies (3). Bars represent arithmetic mean ED50 titers, and symbols are four-parametric ED50 titers of individual mice. P values represent a two-tailed t test between week 4 rPA-HLT TCI groups and week 4 rPA-alum i.m. immunized mice with the values included on the graph or week 6 TCI versus week 6 i.m. immunized mice.
