The invention relates to parasites, and to methods for purifying a metabolically active obligate parasite of vertebrates and arthropods. The invention is especially concerned with methods of purifying Plasmodium and Theileria parasites, such as P. falciparum and T. parva, and highly motile parasite forms thereof, called sporozoites. The invention also relates to obligate parasites of vertebrates and arthropods purified by the methods of the invention and their use thereof.

Disclosed are compositions for stimulating a protective or therapeutic immune response to an apicomplexan parasite such as those from the Plasmodium or Babesia genus. More particularly, the compositions comprise a soluble parasite extract. The extract may be free of red blood cell components and/or contained in or associated with a particle such as a liposome. The compositions and methods disclosed herein are particularly useful in the prevention and treatment of parasitic diseases.
