title: Properties of simian adenovirus 7 after one single passage in simian marmoset lymphoblastoid cells transformed by Epstein Barr virus.
abstract: Simian adenovirus 7 gave an abortive infection in simian marmoset lymphoblastoid cells, B 95-8 and M 81 (transformed by Epstein Barr Virus) whereas non transformed simian lymphocytes could not replicate this virus. Electron dense incomplete particles with a lower density than standard virus in CsCl gradients were isolated. Virus yields were low and the percentage of cells containing viral antigen as measured by immunofluorescence was 0.01% for B 95-8 cells and still less for the M 81 cells. After a single passage in either lymphoblastic cell lines, they had a reduced oncogenicity in vivo. The polypeptide pattern analysis by PAGE showed some modifications.
