Absence of leukosis virus markers in hamster cells transformed by herpes simplex virus type 2.

Hamster cells which transformed after exposure to herpes simplex virus type 2 previously irradiated with ultraviolet light were tested for the presence of hamster leukosis viruses or their virus-specific antigens. Three techniques that were used did not detect the presence of either hamster C-type particles or antigens commonly associated with such structures. The implication of these findings to current concepts of virus oncology is discussed.
