About Carlos Chagas
Carlos Justiniano Ribeiro Chagas (Portuguese: [ˈkaʁluz ʒustʃĩniˈɐ̃nu ʁiˈbejɾu ˈʃaɡɐs]; 9 July 1879 – 8 November 1934), was a Brazilian sanitary physician, scientist, and microbiologist who worked as a clinician and researcher. Best known for the discovery of an eponymous protozoal infection called Chagas disease, also called American trypanosomiasis, he also discovered the causative fungi of the pneumocystis pneumonia. He described the two pathogens in 1909, while he was working at the Oswaldo Cruz Institute in Rio de Janeiro, and named the former Trypanosoma cruzi to honour his friend Oswaldo Cruz. Chagas's work holds a unique place in the history of medicine, Chagas described in detail a previously-unknown infectious disease, its pathogen, vector (Triatominae), host, clinical manifestations, and epidemiology. Chagas was also the first to discover and illustrate the parasitic fungal genus Pneumocystis, which later became infamous for being linked to pneumocystis pneumonia in AIDS patients. For his dissertation, his mentor, Francisco Fajardo, suggested that he work on malaria, as the process of its transmission had been discovered by a British medical officer Ronald Ross in India in 1898.
