Abstract: Plasmodium berghei was subjected to differential centrifugation. Mice immunized with sediments (SI and SIII) emulsified in Freund’s complete adjuvant (FCA) and challenged with 1 × 10000000 live P. berghei showed that SIII imparted complete protection against infection. SIII with FCA or saponin adjuvants showed the latter to be a better adjuvant as postchallenge parasitaemia in mice remained below 2%. Immune sera obtained from the SIII-saponin group inhibited 89% merozoite invasion in vitro. High antibody level was detected by indirect immunofluorescence assay (IFA). Sera collected from S-III immunized mice showed enhanced level of IL-I. Biochemical analysis of sediments revealed SIII to be enriched in acid proteinase and acid phosphatase. The role of parasite component sedimented at 24,000 g in malaria protection is discussed.
