| Abstract |
|
Authors encountered a case of bovine viral leukosis in a young cattle (10 months old) with the following findings; Main clinical symptoms observed were emaciation, digestive disorder, and marked enlargement of superficial lymph nodes. Biopsied specimen of the lymph nodes revealed characteristic histological picture of bovine leukosis. A severe degree of leukocytosis (108,000/cmm) accompanied by marked lympocytosis (96%=103,680/cmm) was detected from the hematological examination of peripheral blood. Most of the lympocytes(94%=101,520) were large-sized, immature, and abnormal in their morphology. In addition, a pronounced anemia (1.78 million/cmm) without regenerative evidence of erythrocyte was noted. The serum of the patient showed positive reaction against gp antigen of bovine leukosis virus in agar-gel diffusion test. |
