Abstract
In the Brazilian Amazon, the suspected source of infection in an outbreak of acute Chagas disease involving 10 patients was Euterpe oleracea (açaí berry) juice. Patient blood and juice samples contained Trypanosoma cruzi TcIV, indicating oral transmission of the Chagas disease agent.
Highlights
In the Brazilian Amazon, the suspected source of infection in an outbreak of acute Chagas disease involving 10 patients was Euterpe oleracea juice
glucose-phosphate isomerase (GPI) sequence analysis showed that the human blood and açaí juice T. cruzi samples could be consistently classified as TcIV discrete typing units (DTUs) [8] (Figure 2, panel C)
Alignments of sequences from cytochrome oxidase subunit II (COII) and GPI T. cruzi genes showed that the parasites in the açaí juice were the same
Summary
In the Brazilian Amazon, the suspected source of infection in an outbreak of acute Chagas disease involving 10 patients was Euterpe oleracea (açaí berry) juice. Thick blood smears from the other 9 patients, all with acute febrile syndrome, were positive for T. cruzi. Of these 10 patients, 8 were clinically assessed at FMT-HVD and submitted samples for direct xenodiagnosis and peripheral blood for T. cruzi culture and PCR.
