In 1960, QIMR Berghofer scientists isolated "Murray Valley encephalitis virus" from mosquitoes, which paved the way for discovery of other arboviruses like Ross River virus in 1963. During the 1960s, QIMR Berghofer established an oncology section to investigate cancer-causing viruses. One project researched cancer cells taken from Burkitt's lymphoma patients in Papua New Guinea, and found they were infected with Epstein-Barr virus (EBV). EBV is now known to cause many types of leukaemias and lymphomas. Eight years later, this same virus was found to immortalise white blood cells; a discovery that revolutionised research of these immune cells and their DNA.
