"... there is a student and a project before the Seminário Laveran & Deane and a student and a project after the Seminário Laveran & Deane.

Anne Caroline Alves Meirelles, Master student of the Experimental Biology Program of the Universidade Federal de Rondonia (XXII SL&D, 2017)

"... as the Samaúma – tree of life, queen of the forest ... symbol of immortality, union and harmony –, the (Seminar) Laveran (& Deane) has outstanding nobility ... and a greatness of its own that welcomes, protects, communicates and teaches us. "...

Djane Baía, PhD candidate of the Tropical Medicine Program of the Universidade do Estado do Amazonas (XX SL&D, 2015) when electing the majestic Samaúma tree from the Amazon forest to represent the SL&D

Created in 1995, the year of the 95th anniversary of the Instituto Oswaldo Cruz, the Seminários of the Instituto Oswaldo Cruz aim for stricto sensu post-graduation students developing their thesis’ projects.

The Seminários, inspired by a French initiative, are strictly dedicated to malaria and initially referred to as the Laveran Seminar, honor Alphonse Laveran, a French military surgeon on duty in Algeria. Laveran was the first to perceive and describe the malaria parasite Plasmodium upon examining a fresh blood smear of a patient in 1880, which awarded him the Nobel Prize.

In the following years, the second (1996), third (1997) and fourth (1999) Seminários do Instituto Oswaldo Cruz honored not only Alphonse Laveran, but also Batista Grassi, a great Italian scientist who, in collaboration with his colleagues Amico Begnani and Giuseppe Bastinelli, described the cycle of the Plasmodium in the Anopheles mosquito, between 1898 and 1899, providing a decisive contribution for the construction of the infection’s transmission.

On 2000, the centennial of the Instituto Oswaldo Cruz, the Seminários do Instituto Oswaldo Cruz became the Seminários Laveran & Deane, reverencing, in addition to Alphonse Laveran, the greatly missed Professor Leônidas Deane, deceased in January 1993. Leônidas, a Brazilian physician and researcher and a renowned international parasitologist, had unquestionable experience in fieldwork and animal capture techniques. He studied malaria (his great passion) transmitted by the Anopheles gambiae in Ceará State together with the biology of this vector. Leônidas participated in the campaign for the eradication of the A. gambiae in the Northeast of Brazil, one of the most successful feats in the history of public health in Brazil. Furthermore, in association with his wife Maria Deane, he conducted the largest study encompassing the biology and the geographical distribution of malaria vectors in the Amazon. Leônidas conferred to us the honor of naming the building, opened in 2000 in the campus of Fiocruz, housing the Laboratory of Malaria Research, cradle of the SL&D.
