Twelve to 14 days after intravenous inoculation of MC29 virus (1 x 105 LD50) into 1-day-old turkeys, liver tumour developed in 100% of the infected animals and led to death of birds. The tumour proved to be hepatomas histologically and electron microscopically. Numerous C-type particles were detectable among the tumour cells, as well as budding from the cell membrane. C-type particles were also observed in the tumour-free liver tissue in the spaces between the cells, budding was not detectable. Large Numbers of virus particles were found in spleen extracellularly and intracellular vacuoles. Kidney tumours did not develop, but a few extracellular virus particles were located in the tissue. The MC29 virus-induced primary liver tumour in the turkey seems to be a suitable model for the morphological study of the relationship between oncogenic viruses and eukaryotic cells.
