Contributions to Science

While studying different invertebrates, Metchikoff saw "special" cells eating foreign bodies such as bacteria. This finding that antibodies are not the only hing that fights disease, intrigued both other scientists and his students to learn more about the immune system. He has gone on to write books such as "The nature of Man" published in 1903 in which he talked about ways of living healthy
