Characterization of a polymorphic immunodominant molecule in sporozoites and schizonts of Theileria parva.

abstract：:Studies in animal models suggest that protection against malaria induced by intradermal (ID) administration of sporozoites is less effective compared to intravenous injection (IV). We investigated in a murine model the protective efficacy and immune responses after ID or IV immunization of sporozoites. Mice were immun...
