Babesia spp. are major hemoprotozoan parasites in animals. Exoantigens, which are soluble antigens released by the parasites during their asexual development, have been successfully applied for the development of a vaccine against babesiosis. In this study, we examined the ability of exoantigens to induce protective immunity in mice against a rodent Babesia parasite, Babesia rodhaini. The BALB/c mice immunized with the blood plasma fraction of B. rodhaini-infected mice (B. rodhaini exoantigens) showed a significant decrease in the lethal rate when challenged with B. rodhaini. Western blot analysis with anti-B. rodhaini exoantigen immune serum specifically detected at least eleven proteins in the lysate of B. rodhaini-infected erythrocytes. Next, a cDNA...
