title: Rapid transmission of sheep pulmonary adenomatosis (jaagsiekte) in young lambs. Brief report.
abstract: Jaagsiekte, a contagious lung tumour of sheep, was induced within 3-6 weeks in day-old lambs by intratracheal inoculation of SPA lung fluids concentrated by centrifugation. Electronmicroscopic examination of the tumour revealed retrovirus particles whose morphogenesis and morphology support biophysical and immunological findings that suggest a relationship with type B and type D retroviruses.
