Burnet, Sir Macfarlane

▪ Australian physician
in full  Sir Frank Macfarlane Burnet 
born Sept. 3, 1899, Traralgon, Australia
died Aug. 31, 1985, Melbourne

      Australian physician, immunologist, and virologist who, with Sir Peter Medawar (Medawar, Sir Peter B.), was awarded the 1960 Nobel Prize for Physiology or Medicine for the discovery of acquired immunological tolerance, the concept on which tissue transplantation is founded.

      Burnet received his medical degree in 1924 from the University of Melbourne and performed research (1925–27) at the Lister Institute of Preventive Medicine, London. After receiving his Ph.D. from the University of London (1928), he became assistant director of the Walter and Eliza Hall Institute of Medical Research at Royal Melbourne Hospital in 1934 and later (1944–65) was its director and professor of experimental medicine at the University of Melbourne. He was knighted in 1951.

      Early in his career, Burnet conducted fundamental experiments with bacteriophages (bacteriophage), and he developed a technique—now standard laboratory practice—of culturing viruses (virus) in living chick embryos. He increased knowledge of the way influenza viruses cause infection, and he carried out or was associated with research on myxomatosis, Murray Valley encephalitis, toxic staphylococcal infection (staphylococcus), polio, psittacosis, herpes simplex, poxviruses (poxvirus), and Q fever. He isolated the causal organism of Q fever, Rickettsia burnetii (Coxiella burnetii).

      Although Burnet's work in virology was important, his most significant achievements in science were made in immunology. He helped unravel the question of how the vertebrate immune system learns to distinguish between its own cells and foreign materials (antigens (antigen)), such as those of infectious agents, and how during development a vertebrate becomes able to tolerate those components belonging to itself—the concept called immunological tolerance. He also developed a model, called the clonal selection theory of antibody formation, that explains how the body is able to recognize and respond to a virtually limitless number of foreign antigens. The theory states that an antigen entering the body does not induce the formation of an antibody specific to itself—as some immunologists believed—but instead it binds to one unique antibody selected from a vast repertoire of antibodies produced early in the organism's life. Although controversial at first, this theory became the foundation of modern immunology.

      Among Burnet's publications are Viruses and Man (1953), Principles of Animal Virology (1955), The Clonal Selection Theory of Acquired Immunity (1959), Immunological Surveillance (1970), and Credo and Comment: A Scientist Reflects (1979).
