Abstract
Hamster embryo cells, following infection with IBR virus, showed malignant transformation. Hamsters of all ages, inbred or random bred, inoculated with two of the transformed cell lines developed solid tumors. Preliminary characterization of the tumors induced by one of the cell lines has indicated undifferentiated sarcomas. Viral specific antigen was detected in about 5% of the transformed cells and 10% of primary tumor cells in culture. Viral specific antibody was detected in the serum of tumor-bearing hamsters by the indirect immunofluorescent method, but no neutralizing antibodies were found. Infectious virus has not been recovered from either the transformed or tumor cells by cocultivation with bovine embryonic kidney cells.
