Research Abstract

Sialic acids and Heparan sulfate located on erythrocytes were demonstrated to play important roles as infectious receptors in the erythrocyte invasion by Babesia parasites. In contrast, several protozoan proteins were also identified as new protozoan ligand candidates. Effects of glycoconjugates or specific antibodies on interfering the specific interactions between the protozoan ligands and erythrocyte receptors would provide us novel knowledge or materials for the development of chemotherapeutic and preventive mesures against babesionsis.
