babesia bigemina: identification of b cell epitopes associated with parasitized erythrocytes. | rhoptries are involved in host cell invasion and rhoptry polypeptides, including the babesia bigemina rhoptry-associated protein-1 (rap-1), are targets for protective immune responses. polyclonal antisera produced against isolated rhoptries is directed predominantly against rap-1 and reacts with both the merozoite and the membrane of parasitized erythrocytes. to determine whether these b cell epitopes associated with the parasitized erythrocyte are derived from rap-1 or, alternatively, from prev ... | 1995 | 8542990 |
