Type A oncornavirus-like particles in turkey bone marrow cells transformed by avian leukemia virus.
Type A oncornavirus-like particles (TAOLP) were found in the cytoplasm of turkey bone marrow cells transformed by strain Mc-31 avian leukemia virus. They resembled morphologically the cores of budding virions and the cores of immature extracellular Mc-31 virus particles. TAOLP were observed more often in T3Mc31 cells where cytopathological changes existed. TAOLP were not found in the materials from in vivo experiments. A relationship is likely to exist between TAOLP and Mc-31 virus and TAOLP could represent a side product of Mc-31 virus replication.
