In the years around 1900 one of the most significant practical consequences of new styles of bacteriological thought and practice was the development of preventive vaccines and therapeutic sera. Historical scholarship has highlighted how approaches rooted in the laboratory methods of Robert Koch, Louis Pasteur and their collaborators were transformed in local contexts and applied in diverse ways to enable more effective disease identification, prevention and treatment. Amongst these, the anti-anthrax serum developed by the Italian physician Achille Sclavo (1861–1930) has (...) received little to no attention from historians. This article positions Sclavo's serum as a neglected but significant presence in British microbiology, which achieved widespread uptake amidst a wave of optimism, despite prolonged uncertainty about its mechanism of action and dosage. After being introduced to Britain in 1904 by the enterprising first medical inspector of factories Thomas Morison Legge, within a matter of months the serum became regarded by medical practitioners as an effective treatment of cutaneous anthrax, though access to ‘fresh’ serum and the necessary speedy diagnosis remained problematic. Like the disease anthrax itself, discussion of ‘Sclavo's serum’ was out of all proportion to the relatively low number of cases, reflecting a deep-seated fascination with the wider possibilities afforded by effective serum therapy.

The present article examines the material, epistemological, and social dimensions of late nineteenth-century anti-cholera serum controversies that unfolded in Tokyo and Berlin. It seeks to shed light on the conflicting values embedded in the construction of scientific evidence during the transnational exploration of bacteriology as an effective response to controlling epidemics. Driven by Japanese health authorities’ initiatives, Japanese bacteriologist Kitasato Shibasaburo participated in the elaboration of bacteriological research oriented toward therapeutic application during his stay in Berlin. This work coincided with (...) the rise of a controversy over anti-cholera serum in relation to the animal experiments conducted by Richard Pfeiffer, a German bacteriologist. After presenting a series of animal experiments and certain clinical cases conducted in Germany, France, and Egypt in the context of the controversies, the article analyzes a therapeutic trial conducted by Kitasato in Japan during an 1895 cholera epidemic. His strategy, bringing new data to the transnational debate through an intensive investment of resources in the trial, provoked criticism from his Japanese and German colleagues. These critics questioned Kitasato’s method and pointed out the low social value of this experimental serum therapy, performed in highly equipped conditions. Through this case study, the present article highlights: a) a strong tension between transnational research interactions among bacteriologists and local medical practices during public health campaigns against epidemics at the turn of the twentieth century; b) the importance of analyzing the interconnected effects of local, national and transnational frameworks of medical science when examining the increasingly intertwined relationships between laboratory science and clinical medicine.
