[The institutionalization of bacteriology in Japan].

Within the history of public health in Japan, Shibasaburo Kitasato is widely known for introducing bacteriology to Japan in the Meiji. This paper looks into the factors behind the success of the Institute of Infectious Diseases(IID), which Kitasato headed, focusing specifically on Kitasato's strategy, institutional rivalries in the medical world and early development in the field of bacteriology. Kitasato used IID to spread bacteriology through a bacteriology training course and the publication of a professional journal, both modeled on the German system, which Kitasato absorbed during his previous studies in Germany under Robert Koch, who was one of the founders of bacteriological science. At the time, doctors related to the university system and those related to sanitary administration competed for leadership in the medical world in Japan. The latter had pushed for IID to be established, and the outbreak of plague in 1899 gave them the opportunity to successfully lobby the Diet into passing legislation that enlarged enrollment in the bacteriology course and earmarked money specifically to IID. In the late 19th century, the application of knowledge from the nascent field of bacteriology led to major advances in the fight against infectious diseases, which led to rapid accumulation of knowledge about bacteria, in turn. Thus, Kitasato emphasized that bacteriology should be mission-oriented and based in sanitary administrations. Indeed, as sanitary administrations were on the frontline of the battle against infectious diseases and as IID laboratories were connected to the sanitary administrations, IID succeeded in dominating the field of bacteriology.
