title: An unusual presentation of enzootic bovine leukosis.
abstract: A 6-year-old, Holstein x Simmental cow diagnosed with pyelonephritis had increasing difficulty rising and became recumbent, despite treatment with antibiotics. A serological test for the bovine leukemia virus was positive; at necropsy, the left kidney and ureter and the myocardium showed lesions of lymphosarcoma, confirmed by histology.
