Gerbils without Borders: Invasiveness, Plague, and Micro-Global Histories of Science, 1932-1939.

In the 1930s, a series of bubonic plague outbreaks among humans cropped up in several villages at the border of Angola and Namibia. These outbreaks provoked deep concern, laying bare social and political tensions amongst neighboring imperial powers and Indigenous people within the region. Despite the appearance of this disease in what was then considered a recondite place, its spread sparked debate in transnational forums, such as the League of Nations and the Office International d'Hygiène Publique.

Of rats and children: plague, malaria, and the early history of disease reservoirs (1898-1930).

This article's jumping-off point is the highly incisive but often-ignored claim by the French doctor, Louis-Jacques Tanon, in 1922 that rats acted as plague reservoirs in Paris; in other words, that they harboured the plague bacillus but were refractory to it. This claim partially reframed the fight against this disease in the French capital in the 1920s, which became more centred on surveilling the plague reservoir rather than on destroying rats. Drawing upon Tanon's hypothesis, this article explores the emergence, evolution, and several iterations of the idea of disease reservoirs in the early twentieth century.

Introduction: Disease Reservoirs: From Colonial Medicine to One Health.

The introduction of the special issue "Disease Reservoirs: Anthropological and Historical Approaches" sets out the origins and trajectories of disease reservoir frameworks. First, it charts the emergence and elaborations of the reservoirs concept within and across early 20th-century colonial contexts, emphasising its configuration within imperial projects that sought to identify, map and control spaces of contagion among humans, animals, and pathogens. Following this, it traces the position the reservoir framework assumed within post-colonial practices and imaginaries of global health, with particular reference to the emerging infectious disease paradigm.

Between Deserts and Jungles: The Emergence and Circulation of Sylvatic Plague (1920-1950).

I trace the development of the concept of sylvatic plague - the first sylvatic disease - examining its invention by Ricardo Jorge to describe a global phenomenon of plague reservoirs among wild rodents, and its circulation. The concept implied a space where plague was enzootic, and relied on a division between inhabited and uninhabited spaces and between domestic rats and wild rodents. Some of the characteristics of this space varied, but it always referred to places imagined as empty of humans and rats.

From Bombay to Rio de Janeiro: the circulation of knowledge and the establishment of the Manguinhos laboratory, 1894-1902.

In order to understand the 1900 establishment of the Federal Serum Therapy Institute of Manguinhos and its earliest scientific work, we must analyze the circulation of knowledge and international disputes surrounding antiplague serums and vaccines. This article discusses the development of the first antiplague serum, in Paris, and the trials conducted in India, which started in 1897. It also examines the invention of an antiplague vaccine in Bombay around the same time and the ensuing controversy involving it and the French serum.

["I do not wish to be controversial": the arrival of the plague in Brazil; analysis of a controversy, 1899].

This article analyzes a debate brought to the public arena by Jornal do Commercio newspaper in August and September 1899 involving two sanitation officials: Nuno de Andrade, Director-General of Public Health, and Jorge Pinto, Director of Hygiene and Public Welfare of the State of Rio de Janeiro. The issue in question was the measures taken by the federal government to prevent bubonic plague reaching Brazil from Porto, Portugal, where there was an epidemic. The theoretical framework for the analysis is Pierre Bourdieu's notion of field, and Bruno Latour's studies into scientific controversy.
