An outbreak of malignant catarrhal fever (MCF) resulted in the deaths of 12 cattle in a herd of 77 animals during seven weeks in 1999; in addition, one cow developed a milder disease which was confirmed as MCF by PCR for ovine herpesvirus 2 DNA and an immunofluorescent antibody test for antibodies to the virus, but recovered. Further PCR and serological testing revealed the infection in three other animals, none of which developed clinical disease. Hypocuprosis and the possibility of a genetic predisposition were identified as factors which may have contributed to the outbreak.
