Summary
Monoclonal antibodies specific for equine herpesvirus 1 (EHV-1) glycoproteins (gB, gD, gp2 and a cleaved translation product of gene 71) were tested for ability to inhibit cell-cell fusion as measured by syncytium formation in EHV-1 infected cell cultures. Syncytium formation was inhibited by a complement-dependent neutralising antibody (7B10) which recognised the large subunit of EHV-1 gB. This indicated that EHV-1 gB, in common with gB homologues of herpes simplex virus and other herpesviruses, plays a role in the cell-cell fusion process.
