Relation between common antigen and membrane antigens associated with Marek's disease herpesvirus and turkey herpesvirus infections

Abstract

The appearance of two kinds of membrane antigen (MA) in Marek's disease herpesvirus (MDHV) or herpesvirus of turkey (HVT) infected cells was examined using antiserum to the common antigen (common-Ag). No early-appearing MA(EMA) was detected in these cultures until 16 hours post-inoculation, after which a number of cells in these cultures had late-appearing membrane antigen (LMA) as detected by immunofluorescence (IF). Fluids from cultures infected with these viruses were examined for the presence of the common-Ag by agar-gel precipitation (AGP) test. No common-Ag was detected until 16 hours, but after 24 hours, it was detected by AGP test. These results suggest that the common-Ag is related to LMA but not to EMA.
