Absence of experimental cross-protection induced by a Trypanosoma cruzi-like strain isolated from bats Ausência de proteção cruzada experimental induzida por uma cepa Trypanosoma cruzi-like isolada de morcego

Revista da Sociedade Brasileira de Medicina Tropical, 2008
This study evaluated the possibility of inoculation and reinoculation with a trypanosomatid isolated from bats that is morphologically, biologically and molecularly similar to Trypanosoma cruzi, to protect against infection by virulent strains.

Extraordinary Trypanosoma cruzi diversity within single mammalian reservoir hosts implies a mechanism of diversifying selection. [PDF]

, 2011
Trypanosoma cruzi is an evolutionarily ancient parasitic protozoan endemic to the Americas. Multiple genetic and phenotypic markers indicate that this parasite is highly diverse, with several divergent and discrete major genotypes reported.

American tripanosomiasis: a study on the prevalence of Trypanosoma cruzi and Trypanosoma cruzi-like organisms in wild rodents in San Luis province, Argentina Tripanosomiasis americana: um estudo sobre a prevalência do Trypanosoma cruzi e Trypanosoma cruzi-like em roedores silvestres da provincia de San Luis, Argentina

Revista da Sociedade Brasileira de Medicina Tropical, 2010
INTRODUCTION: Chagas disease is caused by Trypanosoma cruzi. Wild and perianthropic mammals maintain the infection/transmission cycle, both in their natural habitat and in the peridomestic area.

Genotyping of Trypanosoma cruzi: systematic selection of assays allowing rapid and accurate discrimination of all known lineages. [PDF]

, 2009
Trypanosoma cruzi, the agent of Chagas disease, can be subdivided into six discrete typing units (DTUs), TcI, TcIIa, TcIIb, TcIIc, TcIId or TcIIe, each having distinct epidemiologically important features.

Multiple mitochondrial introgression events and heteroplasmy in trypanosoma cruzi revealed by maxicircle MLST and next generation sequencing. [PDF]

, 2012
BACKGROUND: Mitochondrial DNA is a valuable taxonomic marker due to its relatively fast rate of evolution. In Trypanosoma cruzi, the causative agent of Chagas disease, the mitochondrial genome has a unique structural organization consisting of 20-50 ...

Trypanosoma madeirae sp. n.: A species of the clade T. cruzi associated with the neotropical common vampire bat Desmodus rotundus

International Journal for Parasitology: Parasites and Wildlife, 2019
Molecular phylogenetic studies have revealed the growing diversity of bat trypanosomes. Here, 14 isolates from blood samples of the vampire bat Desmodus rotundus (Phyllostomidae) from Rio de Janeiro, Southeast Brazil, were cultivated, and morphologically

Infectivity of amastigotes of Trypanosoma cruzi [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 1986
The infectivity amastigotes of Trypanosoma cruzi, isolated from the supernatant of the J774G8 macrophage-like cell line infected with trypomastigotes to normal macrophages in vitro was tested. After a period of 1 h of T. cruzi-macrophage interaction about 2% of the mouse peritoneal macrophages had ingested amastigotes.

Ecological host fitting of Trypanosoma cruzi TcI in Bolivia: mosaic population structure, hybridization and a role for humans in Andean parasite dispersal. [PDF]

, 2015
An improved understanding of how a parasite species exploits its genetic repertoire to colonize novel hosts and environmental niches is crucial to establish the epidemiological risk associated with emergent pathogenic genotypes.
