Figure 6: A) Level of protection against C. neoformans infection conferred by immunization with different forms of vaccine preparation. Animals were immunized i.p with different vaccine formulations and were given two boosters. Fungal burden in the kidney was determined after challenging the mice with 5 × 104 cells of C. neoformans The mean cfu in 8-10 mice from each group was calculated (A) 5 days post infection (B) 15 days post infection. Each bar represents the mean of three determinations ± S.D
