Abstract :
[en] Evolution of sensitizing antibodies involved in antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-complement cell lysis and complement-facilitated ADCC was followed in bulls after primary infection by a wild strain of infectious bovine rhinotracheitis virus (bovine herpesvirus 1; BHV-1) and after experimental reactivation of the virus. These antibodies were detected between the 4th and the 7th day after primary infection, reached a maximum level after 2 weeks and rose slightly after reactivation of the virus following dexamethasone treatment. The presence of endogenous complement slightly enhanced the ADCC reaction.
