title: [Study and identification of the respiratory syncytial virus isolated from a leukemic cow].
abstract: A virus was isolated from the lymph nodes of a cow. By its cultural, physical, chemical, and biologic properties it proved identical with the standard bovine respiratory syncytial virus. It multiplied well in cell cultures of calf kidney at pH 7--7.5. Introduced in 20-day-old guinea pigs the virus caused anorexia, bristling up of hairs, stunting, and occasionally death. The inoculated guinea pigs developed pneumonia of a proliferative type with Langhans' giant cells. The interrlationship between the isolated virus and the standard oncorna virus, type C, is discussed.
