Evidence for an oncogenic potential of the Epstein-Barr virus.

The search for human tumor viruses has depended and undoubtedly will continue to depend largely on indirect approaches based upon techniques and experiences derived from studies on virus-induced animal tumor models. It is gratifying, therefore, to see for once an at least partial reversal of this trend; i.e., to find that work with a potentially oncogenic human virus, especially its seroepidemiological aspects, may serve now as pattern for similar studies on animal or other human viruses of known or suspected oncogenicity. The human virus is EBV4 which
