RESUMEN
Following the medical breakthroughs of Pasteur and Koch after 1880, the use of simians became pivotal to laboratory research to develop vaccines and cultivate microbes through the technique of serial passage. These innovations fueled research on multiple diseases and unleashed a demand for simians, which died easily in captivity. European and American colonial expansion facilitated a burgeoning market for laboratory animals that intensified hunting for live animals. This demand created novel opportunities for disease transfers and viral recombinations as simians of different species were confined in precarious settings. As laboratories moved into the colonies for research into a variety of diseases, notably syphilis, sleeping sickness, and malaria, the simian market was intensified. While researchers expected that colonial laboratories offered more natural environments than their metropolitan affiliates, amassing apes, people, microbes, and insects at close quarters instead created unnatural conditions that may have facilitated the spread of undetectable diseases.

From about 1880 to 1920, a culture of medical experimentation promoted blood transfusion as a therapy for severe anemia in Europe, which was applied in German East Africa in 1892 for a case of blackwater fever, a complication of malaria afflicting mainly Europeans. This first case of blood transfusion in Africa, in which an African's blood was transfused into a German official, complicates the dominant narrative that blood transfusions in Africa came only after World War I. Medical researchers moreover experimented with blood serum therapies on human and animal subjects in Europe and Africa, injecting blood of different species, "races" and ethnicities into others to demonstrate parasite transmissibility and to discover vaccines for diseases such as malaria, sleeping sickness, and yellow fever. While research in German colonies is highlighted here, this was a transnational medical culture that crossed borders and oceans. This research is of interest as a possible early pathway for the epidemic spread of HIV and other zoonoses in Africa and the world, which biomedical researchers have identified as emerging in West-Central Africa sometime around the turn of the twentieth century.

Scholarship on the Tanzanian Rinderpest epizootic of the 1890s has assumed that German colonizers understood from the start that they were confronting the same disease that had afflicted Eurasia for centuries. Outward indicators of the epizootic, known locally as sadoka, especially wildlife destruction, were unknown in Europe, leading German veterinarians to doubt that the African disease was Rinderpest. Financial constraints and conflicting development agendas, especially tension between ranching and pastoralism, deterred early colonial applications of veterinary science that might have led to an early diagnosis. European veterinarians, guarding their authority against medical researchers, opposed inoculation therapies in the case of Rinderpest in favor of veterinary policing despite recent breakthroughs in vaccine research. The virus was not identified before reaching South Africa in 1896, but this breakthrough had little influence on policy in East Africa. Yet emergent international disease conventions directed at bubonic plague entangled with veterinary policy in East Africa.
