A collection of venomous snakes, along with venomous lizards, spiders, insects and scorpions, is what the Instituto Butantan is best known for. The animals are central to its work: venom extracted from them is used to develop antivenoms and medicines against diseases including tuberculosis, rabies, tetanus and diphtheria.
Founded in 1901, the institute is a biological research center in Butantã, in the western part of São Paulo. It is a public institution affiliated with the São Paulo State Secretariat of Health. It is the largest producer of immunobiologicals and biopharmaceuticals in Latin America and one of the largest in the world. Its museum is part of a working scientific center, and it suits visitors curious about venomous animals and the science of turning their venom into medicine.
