title: Persistence of antibody in calves after an infection with Hypoderma bovis.
abstract: The antibody titre of seven calves, naturally infected with Hypoderma bovis, was estimated by an enzyme-linked immunosorbent assay (ELISA) on sera collected from June to early December 1983 following infection in 1982. It was found that the antibody was lost from the circulation of these animals about 14 weeks after the disappearance of the infection. It is suggested that the presence of antibody in the sera of calves sampled in the late autumn and winter indicated that a new infection had been acquired.
