ABSTRACT

This paper reports a case of enzootic bovine leukosis in a 3-year-old cowtreatedat the Veterinary Hospital of the University of Brasília. This animal presented characteristic clinical findings of the disease like exophthalmia, paresia of the hind legs, growth of superficial lymph nodes, and a hard palpable mass localized inside the left uterine horn. At the necropsy there were observed white masses of hard or soft consistencies with nodular or diffused formation invarious organs like the heart, rumen, uterus, lungs, medulla, kidneys and retro-bulbar tissue behind the right eye. The hematological exam showed leukocytosis with pleomorfism, vacuolated cytoplasm, and the presence of flamejant plasmocytes. The chemical examination of the liquor revealed reduction of the glycemic level. The clinical finding associated with the necropsy findings and laboratorial results contributed to a suspicion of enzootic bovine leukosis.
