Abstract
Soluble antigen, specific for Babesia parasites, is isolated from growth media of Babesia-infected erythrocytes in cell culture and characterized, inter alia, by its ability to inhibit the capacity of specific Babesia serum antibodies to neutralize infectivity of Babesia merozoites in vitro. Antigen preparations provide immunologically active components useful for vaccination of animals against infection by Babesia parasites and may be employed in the preparation of diagnostic reagents.
