Isolation of an infectious oncogenic adenovirus strain from the stimulated lymphocytes of a patient with bladder tumour.

In attempts to grow viruses from tumour cells and circulating lymphocytes, we isolated an oncogenic infectious adenovirus type 18 strain from the phytohaemagglutinin-stimulated peripheral T-lymphocytes of a patient with bladder tumour. The virus genome is assumed to play certain role in the development of the tumour in interaction with other DNA viruses and the damaged immune system.
