EVIDENCE FOR A POSSIBLE GENETIC HYBRID BETWEEN ADENOVIRUS TYPE 7 AND SV40 VIRUSES

Abstract
A passage line of Ad. 7 which had been freed of SV40 contamination induces an SV40 antigen in acutely infected tissue culture cells. The SV40 antigen-inducing capacity is integrally associated with the Ad. 7 infectious particle, suggesting incorporation of a portion of the SV40 genome into the Ad. 7 virion.
