Survival in vaccinated Balb/C mice following challenge with purified. C. difficile toxins. Balb/C mice (10 mice/group) were challenged i.p with (a) 50 ng TcdA; (b) 25 ng TcdB; or (c) 50 ng TcdA and 25 ng TcdB. 10 days following the second boost DNA immunization, and monitored for survival for 14 days. *, P ≤ 0.05; ***, P ≤ 0.001. Data from two replicate experiments are shown
