摘要

Concurrent infection with bovine leukaemia virus (BLV) and Theileria annulata was diagnosed in a Friesian calf about 6 months of age at a dairy farm at the Qassim region of central Saudi Arabia. The disease ended fatally with signs of liver and heart failure. There was anorexia, pyrexia, anaemia, generalized oedema and jaundice. Haematology showed low RBC counts, PCV percentage and haemoglobin concentration and WBC counts. Lymphocyte differential was high. Examination of blood smears stained with Giemsa’s stain showed the presence of piroplasms in red blood cells. Autopsy showed enlarged lymph nodes and lymphosarcoma lesions in the omentum and the heart. There was hydroperitoneum, hydropericardium and hydrothorax. The liver was pale yellow and friable. Impression smears from sliced lymph nodes and stained with Giemsa’s stain showed presence of Koch’s blue bodies in lymphoblasts. Histopathological examination revealed fatty degeneration of hepatocytes and pleomorphic lymphoblasts and giant cells in lymph nodes. Lymphoblasts infiltrated the omentum and heart tissues. Amyloid was found around blood vessels in the liver, kidneys and lymph nodes. BVL infection was diagnosed by demonstrating antibodies against the virus in serum using agar gel immunodiffusion and was confirmed with ELISA.
