Genetic profiling of Trypanosoma cruzi directly in infected tissues using neste...
Pimenta, Juliana Ramos; Freitas, Jorge Marcelo de; Duffy, Tomás; Bartholomeu, Daniella Castanheira; Oliveira, Riva de Paula; Chiari, EglerThe investigation of the importance of the genetics of Trypanosoma cruzi in determining the clinical course of Chagas disease will depend on precise characterisation of the parasites present in the tissue lesions. This can be adequately accomplished by the use of hypervariable nuclear markers such as microsatellites. However the unilocal nature of these loci and the scarcity of parasites in chronic lesions make...
Unequivocal identification of subpopulations in putative multiclonal Trypanosom...
Valadares, Helder Magno Silva; Pimenta, Juliana Ramos; Segatto, Marcela; Veloso, Vanja Maria; Gomes, Mônica Lúcia; Chiari, Egler; Gollob, Kenneth JohnTrypanosoma cruzi, the etiological agent of Chagas disease, is a polymorphic species. Evidence suggests that the majority of the T. cruzi populations isolated from afflicted humans, reservoir animals, or vectors are multiclonal. However, the extent and the complexity of multiclonality remain to be established, since aneuploidy cannot be excluded and current conventional cloning methods cannot identify all the r...
