Chihiro Sasakawa

is a Japanese bacteriologist well known for his pioneering research into the invasive mechanisms of pathogenic bacteria and the host’s subsequent immune response to infection. In his work on Shigella species and Helicobacter pylori, Sasakawa was an early adopter of a multi-disciplinary research strategy, combining molecular biology, cellular biology, biochemistry and immunological approaches. This research strategy and his discoveries greatly influenced later research on the invasive mechanisms of other pathogenic bacteria. Provided by Wikipedia
