bovine petechial fever

is caused by Ehrlichia ondiri and occurs in Kenya and possibly Tanzania in cattle grazing thick scrub land or indigenous forest areas to 1,500-3,000 meter altitudes. It is manifest by fever and submucosal and serosal hemorrhages. There may be epistaxis and other evidence of a bleeding tendency. Pregnant animals may abort and anemia may result in death 3 to 4 weeks after infection. The disease has a strong similarity to tickborne fever. The method of transmission is unknown. Called also Ondiri disease.

bovine polyomavirus

bovine respiratory disease

a group of undifferentiated diseases of young cattle characterized by dyspnea, coughing, nasal discharge, evidence of pneumonia on auscultation of the lungs, and nonspecific signs as a result of the toxemia of infection and tissue destruction. Because of the complexity of the differential diagnosis of these diseases, it has become common practice to devise treatments and control programs which will deal satisfactorily with them as a group. Called also shipping fever.

bovine respiratory syncytial virus

a member of the family Paramyxoviridae, genus Pneumovirus which causes one of the more virulent forms of enzootic calf pneumonia. Many calves in the group are affected, there is severe dyspnea, and extensive involvement of the lungs. Outbreaks of disease also occur in adult cattle. The mortality rate in all ages can be high.

bovine somatotropin (BST)

a protein secreted by the pituitary gland that stimulates body cell growth and milk production. It is available as a synthetically produced product for use in cattle.

sporadic bovine encephalomyelitis

bovine viral leukosis

a highly fatal, systemic, malignant neoplasm of the reticuloendothelial system of cattle. It is characterized by tumors composed of aggregations of neoplastic lymphocytes in almost any organ with a great variety of clinical syndromes resulting. The causative retrovirus is transmitted in a number of ways, including insect vectors, but only to cattle over about 1.5 years of age. There is a significant component of genetic susceptibility in the etiology of the disease and many animals may receive the virus but not become infected. In those that do, the infection persists for life. One group of these cattle are seropositive and may not progress further. A second group are seropositive and develop a persistent lymphocytosis, a benign disease without further progress. The third group is the one in which the cattle develop malignant tumors, lymphosarcomas, and demonstrate any one or a combination of syndromes. These include abomasal obstruction and ulcer, congestive heart failure, posterior paralysis, pharyngeal obstruction, protrusion of the eyeball, and a cutaneous form with multiple nodes and plaques in the skin. There is also a sporadic occurrence in young cattle, a juvenile form in calves less than 6 months old, and a thymic form in yearlings. The disease is always fatal, often within a few weeks. Called also bovine lymphosarcoma, enzootic bovine leukosis.

bovine virus diarrhea

an infectious disease of cattle caused by a pestivirus. Clinical disease is sporadic and is seen only in young animals. The syndrome includes diarrhea, erosive stomatitis and rhinitis, often with similar lesions at all mucocutaneous and skin-horn junctions. Congenital defects occur in the offspring of females which become infected during pregnancy but do not themselves show clinical signs. The best known defect is cerebellar agenesis. Called also mucosal disease.
