The detection of virus-specific immunoglobulin M (IgM) antibodies in acute-phase serum samples offers the possibility of making an accurate and rapid serologic diagnosis. We have developed a solid-phase capture assay that uses murine monoclonal antibodies specific for bovine IgM to separate the whole IgM fraction of a bovine serum sample. The IgM specific for bovine herpesvirus-1 (BHV-1) is then detected by the addition of viral antigen, which in turn is detected by BHV-1-specific monoclonal antibodies conjugated to horseradish peroxidase. A BHV-1 IgM antibody response was detected during the early postinfection period (7–40 days PI). Bovine herpesvirus-1 IgM antibody was not detected in sera taken from 3 animals following dexamethasone-induced viral reactivation. This method compares favorably with viral isolation, antigen detection in the clinical samples, and paired serology in the diagnosis of BHV-1 infection at a herd level.
