title: Duck hepatitis virus: adaptation of a plaque assay to determine 50 per cent end points with duck sera.
abstract: An assay to determine 50 per cent neutralisation end points of duck anti-duck hepatitis virus sera was developed using a plaque assay to quantify residual virus. The optimal conditions were determined. Ducklings produce a serological response within four days of vaccination and the response reaches a maximum within nine days.
