[en] The biology of bovine herpesvirus-4 (BHV-4) infection of cattle is reviewed. The infection is distributed worldwide. Most of isolated viruses are non-pathogenic in cattle; some of them are able to produce a genital disease. Twenty-nine structural polypeptides were described; ten of them are glycosylated. Two major glycoproteins were characterized by monoclonal antibodies. Restriction maps of BHV-4 DNA are available for the enzymes EcoRI, BamHi and HindIII. The strain variations studied by restriction analysis are very weak. The virus is able to persist in a latent state after primary infection. The identified sites of latency are nervous ganglia and mononuclear blood cells. The immune response of cattle after BHV-4 infection is characterized by low or undetectable levels of neutralizing antibodies. Four envelope proteins are recognized by convalescent sera and are the main antigenic components. Skin test remains negative in immunized cattle. Bovine herpesvirus-4 is not strictly species-specific: infection was proved in American bison (Bison bison), African buffalo (Syncerus caffer), sheep and probably cat, because feline herpesvirus-2 is in fact a BHV-4 strain. Finally BHV-4 shares antigenic and genomic relationships with alcelaphine herpesvirus-1, the causal agent of the African form of malignant catarrhal fever.
