Virus - tumor cell relationships. In vivo cocultivation of para-influenza type 1 (Sendai) virus and of Rous sarcoma virus (Schmidt-Ruppin strain) in mouse Ehrlich ascites carcinoma.
Co-infection of Ehrlich ascites carcinoma (EAC)-bearing mice with Sendai virus and Rous sarcoma virus (RSV) did not result in the formation of complete RSV. Sendai virus could be, however, propagated in this system over 8 serial passages. As demonstrated by immunofluorescence and complement fixation reactions, antigens specific to each virus were synthesized in EAC cells following either single or mixed virus infection. The virus progens also contained antigenic fractions incorporated from the host cell. The incomplete progens synthesized when RSV inoculation preceded that of Sendai virus possessed three polypeptide fractions characteristic of Sendai virus and one RSV-specific fraction.
