Abstract

Os autores apresentam os resultados do estudo epidemiológico de um caso autóctone da fase aguda da doença de Chagas na ilha do Mosqueiro, Estado do Pará, aproximadamente 75km da capital, Belém. 0 caso já havia sido objeto de uma publicação anterior. Agora são apresentadas informações epidemiológicas. Nas proximidades da casa do paciente foram capturados em duas palmeiras de Inajá ('Maximilian regi ay e em uma de Mucajá (Acrocomia sclerocarpia) 114 triatomíneos: Rhodnius pictipes, R. robustus, Panstrongylus lignarius, P. geniculatus e Microtriatoma trinidadensis, com tripanossomas em 31 deles. Na casa do paciente foram encontrados exemplares de Rhodnius pictipes, infectados com formas metacíclicas do Trypanosoma cruzi. Em 14 marsupiais, capturados na localidade, haviam 3 infectados com organismos semelhantes ao T. cruzi. A eletroforese dos isoenzimas nos tripanossomas isolados do paciente, de R. pictipes e de Didelphis marsupialis os classificou como zimodema 1. Os autores concluem que a doença de Chagas do paciente teve origem silvestre.<br>The authors present the results of an epidemiological study relating to a case of acute Chagas' disease acquired in the island of Mosqueiro, State of Para, approximately 75 km from the capital Belem. The patient has been the object of a previous publication but now epidemiological information is reported. Near the house of the patient in two Inaja palm trees (Maximilian regia) and one Mucaja palm (Acrocomia sclerocarpia) 114 triatomine bugs were captured of the following species: Rhodnius pictipes, R. robustus, Panstrongylus lignarius, P. geniculatus and Microtriatoma trinidadensis. Trypanosomes were found in 31 bugs. In the house of the patient specimens of R. pictipes were captured infected with metacyclic forms óf Trypanosoma cruzi. In 14 marsupials captured in the locality three had infections with cruzi like trypanosomes. Enzyme electrophoresis of the trypanosomes isolated from the patient, R. pictipes and Didelphis marsupialis were classified as zymodeme 1. The authors conclude that the patients Chagas' disease was of sylvatic origin
