From the ports to the hinterland. Plague, bacteriology, and politics in Argentina (1899-1940).

In 1899, the first cases of plague were recognised in Paraguay and a few months later in Buenos Aires as part of the third plague pandemic. In the first decades of the twentieth century, plague slowly advanced towards the Argentinian hinterland. In this paper we focus on the production of scientific knowledge about plague in Argentina, where a core of bacteriologists emerged early on. We show how they not only played a central role in the complex process of plague recognition and intervention, but also influenced the scientific development of bacteriology in Argentina and potentially in South America. We argue that bacteriology became a key tool in articulating the promises of modern science with political and economic interests, allowing the Argentinian government to extend its territorial control over Buenos Aires and the hinterland. This can be seen in two different configurations of the plague as an epistemic and political object in Argentina. In the first period, from 1899 to 1910, plague was a problem linked to the ports. In this section of the article, we show how plague became an important issue in the development of bacteriology in Argentina, how this research contributed to new intervention measures and, in some cases, developed innovative ideas about serotherapeutic treatments and the characteristics of the disease. In the second period, from the mid-1910s until the 1940s, research in Argentina provided new evidence of the 'rural' nature of plague, a process in deep dialogue with research on plague among peri-domestic and wild rodents carried out in other parts of the Americas, Europe and Africa. This article thus aims to contribute to a history of bacteriology that highlights the role of non-European centres, like Argentina, in the production and circulation of bacteriological knowledge.
