title: Detection of type A oncornavirus-like structures in chicken embryo cells after infection with Rous sarcoma virus.
abstract: Electron microscopy examination of Rous sarcoma virus-transformed chicken embryo cells revealed membrane-free nucleoids resembling type A oncornavirus. These particles were not detected in noninfected cells, nor did they accumulate in excess under conditions of glucosamine block in virus-transformed cultures.
