Effect of BCG and allogeneic tumour cells on adenovirus type 12 tumorigenesis in mice
HAMSTERS and mice inoculated at birth with tumour viruses have been used in studies of the prophylactic effects of various treatments during the latent period. The incidence of primary tumours in hamsters infected at birth with SV40 is reduced if the virus is inoculated during the latent period1-3. Similar administration of adenovirus type 12 also inhibited the induction of tumours by SV404; this
