✦ Synopsis

Herpes simplex virus type 1 (HSV1) and type 2 (HSV2) polypeptides with type-common and type-unique epitopes were identified using cross-adsorbed hyperimmune rabbit sera and Western blotting techniques. Twelve HSV1 and fourteen HSV2 polypeptides with type-specific epitopes were identified. Cross-adsorbed human sera reacted to a subset of the type-specific epitopes defined by rabbit sera. Human sera with both HSV1- and HSV2-specific antibodies were identified by their reaction to HSV1-type-specific epitopes after adsorption with HSV2, and HSV2-type-specific epitopes after adsorption with HSV1. Mixing experiments demonstrated the sensitivity of this assay for detecting HSV2-type-specific antibody in the presence of HSV1 antibody. This technique has proven useful in the study of immune response to individual HSV polypeptides during human HSV infections, while the presence of these type-unique epitopes on HSV polypeptides allows for the detection of type-specific antibodies in human sera.
