Thirty-one Trypanosoma cruzi isolates from Chile, Peru, and Bolivia were studied in their capacity to differentiate in vitro from epimastigotes to metacyclic trypomastigotes on TAU-3AAG medium. Zymodeme 1 parasites displayed ...

We previously rerported four autochthonous cases of Chagas disease in Bolivia, presenting a particular pattern of negative serology with positive xenodiagnosis (Brenière et al., 1984). To date, we have observed 13 similar ...

With the objective of establishing biological and biochemical characteristics of a significant number of Trypanosoma cruzi strains from different geographical areas, 138 strains isolated from naturally infected humans, ...

Immune sera from mice infected with specific Zymodemes of Trypanosoma cruzi parasites displayed preferential in vitro complement-mediated trypanolytic activity with homologous or genetically related bloodstream trypomastigotes. ...

Kinetoplast DNA was isolated from Chilean Trypanosoma cruzi populations and digested with the restriction endonucleases EcoRI, HinfI, HpaII, MspI, and HaeIII. Three major schizodeme groups were discriminated. There was a ...
