Just over 100 autochthonous cases of Chagas disease are reported from the Brazilian Amazon Basin. Panstrongylus geniculatus (Latreille) occurs throughout the region and is the known vector of Trypanosoma cruzi, principal zymodeme 3 (Z3) to the armadillo Dasypus novemcinctus. In the small riverine community of Furo do Rio Pau Grande, pigsties adjoining houses were heavily infested with P. geniculatus, which repeatedly attacked local inhabitants. Palm trees in the immediate vicinity were also…

Presence of intradomicile colonies of the triatomine bug Panstrongylus rufotuberculatus in Muñecas, La Paz, Bolivia.

Triatomine home invasions in active foci of Chagas disease in Abaetetuba, Pará, Brazil.

Home invasions of triatomines were confirmed in two periods, with a description of unusual behaviour for the genus Rhodnius, and the use of serological surveillance in human populations at risk of this occurrence may constitute a new tool for the early detection of silent infections.

Emerging Chagas disease: trophic network and cycle of transmission of Trypanosoma cruzi from palm trees in the Amazon.

A trophic network involving molds, invertebrates, and vertebrates, ancestrally adapted to the palm tree (Attalaea phalerata) microhabitat, maintains enzootic Trypanosoma cruzi infections in the…

On the possibility of autochthonous Chagas disease in Roraima, Amazon region, Brazil, 2000-2001.

Results show that Chagas disease is not endemic in the areas studied, however, all elements of the transmission cycle are present, demanding for an adequate and continuous vigilance.

Potential for domestication of Panstrongylus geniculatus (Latreille, 1811) (Liemiptera, reduviidae, triatominae) in the municipality of Muaná, Marajó island, state of Pará, Brazil.

The registered adaptability of P. geniculalus toswine and pigsties in the vicinity of human dwell-ings, in the floodplain, and their attack on people in houses, indicate that this could be a potential pathway to the domestication of this triatomine inthe Amazon River delta.

Surveillance of seroepidemiology and morbidity of Chagas disease in the Negro River, Brazilian Amazon

It is found that the highest incidence of infection due to Trypanosoma cruzi and Chagas disease occurred among piassaba fibre gatherers and their families in the creeks of the Aracá, Curuduri, Demini, Ererê and Padauiri rivers.

Bioecological aspects of triatomines and marsupials as wild Trypanosoma cruzi reservoirs in urban, peri‐urban and rural areas in the Western Brazilian Amazon

The results demonstrate the relevance of this study, with the occurrence of elevated infection rates in animals, and suggest the importance of the Amazon zones where there is a risk of infection in humans.

Risks that Chagas' disease will become endemic to the Amazon appear to be linked to the transposition of the wild cycle to the domestic cycle in that area or to transfer of the domestic Cycle from endemic areas to theAmazon.

Vertebrate hosts and vectors of Trypanosoma rangeli in the Amazon Basin of Brazil.

It is concluded that T. rangeli is widely distributed in Amazonas, Pará and Rondonia States of Brazil, and probably extends into other regions where R. pictipes and R. robustus are known to occur.
