title: A blocking ELISA with improved sensitivity for the detection of passively acquired maternal antibodies to BHV-1.
abstract: Four serological tests were evaluated for their ability to detect passively acquired maternal antibodies to Bovine herpesvirus 1. A blocking enzyme-linked immunosorbent assay demonstrated superior sensitivity in the detection of such antibodies in calves up to 9-11 months old, versus calves up to 7 months old for other tests.
