Mouse Response

• Host Strain: BALB/c, C57BL/6 or B10.D2
• Vaccination Protocol: In all protection experiments, mice (n=5–8) were given injections (2×25 μl) of antigen preparation twice subcutaneously (s.c.) at the base of the tail. Before the injection, antigens were either emusified in IFA (1:1, vol/vol), mixed (1:1, vol/vol) with either 0.5 or 1 μg of IL-12 in PBS or prepared in PBS only. Several doses of antigen were tested and parasite challenge in the right hind footpad was performed at different time points after the second injection (Solioz et al., 1999).
• Challenge Protocol: In this long term experiment, mice were challenged two and a half months after the second injection of antigen with 2×106 highly infectious parasites (Solioz et al., 1999).
• Efficacy: When inoculated in the presence of IFA as adjuvant, the partially purified histone H1 was able to confer partial protection in six out of eight mice (Solioz et al., 1999).
