FIG. 3.

IIF IgG reactivity against P. falciparum liver stage parasites in C57BL/6, A/J, BALB/c, and CD1 strains of mice that received three subcutaneous injections of MAP vaccines in Montanide ISA 51. The reactivity for liver stage parasites was tested against (A) polyclonal mouse anti-LSA-1 antibody (positive control), (B) MAP-2-immunized BALB/c mouse sera, (C) C57BL/6-immunized mouse sera, (D) CD1-immunized mouse sera, and (E) normal mouse serum. The arrow points to the developing P. falciparum parasites. The hepatocyte nucleus is stained blue with DAPI.
