The Spanish Society of Microbiology (SEM) is a scientific society founded in 1946 at the Jaime Ferrán Institute, of the Higher Council for Scientific Research (CSIC), in Madrid. Its original name was the Society of Spanish Microbiologists, which it maintained until 1970, when, by decision of its partners, it took the current name of the Spanish Society of Microbiology (SEM).
The SEM's main objectives are: to promote basic and applied microbiology, cultivate international relations, bring together the different professionals who worked in this science, and contribute to the dissemination of science in general, and microbiology in particular, among the citizenship. It is an interdisciplinary society, which has about 1,700 members who work in the different fields of microbiology.
