sheep by administering small doses of venoms, and then extracting, purifying and freeze-drying the antibody portion from the blood of injected animals), Vital Brazil and his coworkers were able to discover the first sera against two species of scorpions' (1908) and spiders' (1925) venoms. In the USA, Vital Brazil's name made the headlines when he used his serum to save the life of a worker in the Bronx Zoo in New York City who was bitten by a rattlesnake. Most important of all, the Butantan Institute became a fertile school for breeding a new generation of Brazilian biochemists, physiologists and pathologists, such as José Moura Gonçalves, Carlos Ribeiro Diniz, Gastão Rosenfeld, Wilson Teixeira Beraldo and Maurício Rocha e Silva, who went on to found a growing number of schools, departments and research laboratories in São Paulo, Rio de Janeiro and Minas Gerais, giving a great impetus to the development of medical and biological research and teaching in Brazil in the second half of the 20th century. According to Bernardo Houssay, who wrote a well-cited biography of Vital Brazil in 1966, his contributions went further than herpetology:"Vital Brazil and his collaborators have studied several actions of the venoms, (such as) coagulant, anticoagulant, hemolytic, agglutinant, cytotoxic, proteolytic, etc. (...) The (animal) poisons contain numerous enzymes which have been isolated and studied with interest in all parts since they explain many of the symptoms and constitute interesting biochemical reagents, Vital Brazil studied also the ophiophagous serpents, such as the mussurana, the ophiophagous mammals, such as the skunk-like Conepatus chilensis and others, the ophiophagous birds and certain spiders. (...) His book, La défense contre l’ophidisme published in French in 1914, attained international repercussion with three editions."
