Abstract

A male, six-year-old pudu (Pudu puda) from an Italian zoo was submitted for postmortem examination after sudden death. Necroscopy revealed non-suppurative bronchopneumonia and degeneration of the liver and haemorrhagic lesions of the thymus, pericardium and spleen. Microscopically, multifocal perivascular mononuclear cell infiltrates were observed in the kidneys, lungs, spleen, and the portal triads of the liver. Histological examination of the brain showed meningitis, vasculitis and perivascular cuffs of mononuclear inflammatory cells. A region of the DNA polymerase gene of malignant catarrhal fever viruses was amplified by real-time PCR and nested PCR. PCR products from the tissue samples were sequenced and analysed. The sequences showed 99% similarity with a portion of the caprine herpesvirus 2 DNA polymerase gene. This is the first report of malignant catarrhal fever in a captive pudu.
