title: Herpesvirus infection in tortoises (Malacochersus tornieri and Testudo horsfieldii).
abstract: Large numbers of pancake tortoises (Malacochersus tornieri) and Horsfield tortoises (Testudo horsfieldii) in three consignments imported into Japan died soon after arrival. Some tortoises in the first consignment were dead on arrival. Postmortem examination of two of the pancake tortoises and four of the Horsfield tortoises revealed necrotizing lesions of the oral mucosa in both species, primarily in the tongue. Eosinophilic to amphophilic inclusion bodies were visible in the nuclei of mucosal epithelial cells in the lesions. Similar inclusion bodies were observed in the liver, spleen, adrenal glands, stomach, lungs, kidneys, small and large intestines, pancreas, and cerebrum of the pancake tortoises and in the liver, spleen, and pancreas of the Horsfield tortoises. Electron microscopic examination of the cells containing inclusion bodies showed herpesvirus-like particles about 100 nm in diameter in the cytoplasm. Nested polymerase chain reaction analysis using a herpesvirus consensus primer method confirmed the presence of a characteristic herpesvirus base sequence in tissue from these lesions.
