In Vivo Imaging of Cardiac Attachment of TcI and TcII Variants of Trypanosoma cruzi in a Zebrafish Model

Pathogens
Trypanosoma cruzi, the etiological agent of Chagas disease, is a parasite known for its diverse genotypic variants, or Discrete Typing Units (DTUs), which have been associated with varying degrees of tissue involvement.

Comparison of Trypanosoma cruzi infection in dogs inoculated with blood or metacyclic trypomastigotes of Berenice-62 and Berenice-78 strains via intraperitoneal and conjunctival routes

Revista da Sociedade Brasileira de Medicina Tropical, 2002
This paper aimed to verify the influence of the inoculum source (blood or metacyclic trypomastigote) and the route of inoculation (intraperitoneal or conjunctival) on the course of T. cruzi infection in dogs, using comparatively the T.

Trypanosoma (Herpetosoma) rangeli Tejera, 1920: intracellular amastigote stages of reproduction in white mice

Revista do Instituto de Medicina Tropical de São Paulo, 1986
The method, site, and stage of multiplication of Trypanosoma (Herpetosoma) rangeli Tejera, 1920 has not hitherto been known. "We have now observed many intracellular nests or pseudocysts, containing amastigotes and trypomastigotes of this parasite in the

Interação entre Trypanosoma cruzi e macrófagos: diferenças entre tripomastigotas sangüí-colas e de cultivo de tecidos Trypanosoma cruzi interaction with macrophages: differences between tissue culture and bloodstream forms

Revista do Instituto de Medicina Tropical de São Paulo, 1984
Macrófagos obtidos do peritoneo de camundongos após estímulo, com peptona, foram cultivados em lamínulas, infectados com tripomastigotas das cepas F e Y de T. cruzi, obtidos de cultivo de tecidos ou do sangue de camundongos infectados.

Surface electrical charge of bloodstream trypomastigotes of Trypanosoma cruzi strains

Memorias do Instituto Oswaldo Cruz, 1983
Bloodstream trypomastigotes of some Trypanosoma cruzi strains were processed through DEAE-cellulose columns under standardized conditions. The results obtained suggest mainly that these strains present different surface charges, that there are ...

Interactions between 4-aminoquinoline and heme: Promising mechanism against Trypanosoma cruzi

International Journal for Parasitology: Drugs and Drug Resistance, 2016
Chagas disease is a neglected tropical disease caused by the flagellated protozoan Trypanosoma cruzi. The current drugs used to treat this disease have limited efficacy and produce severe side effects. Quinolines, nitrogen heterocycle compounds that form

The Trypanosoma cruzi pleiotropic protein P21 orchestrates the intracellular retention and in-vivo parasitism control of virulent Y strain parasites

Frontiers in Cellular and Infection Microbiology
P21 is a protein secreted by all forms of Trypanosoma cruzi (T. cruzi) with recognized biological activities determined in studies using the recombinant form of the protein.

Trypanosoma cruzi Epimastigogenesis: A Method for Studying Trypomastigote to Epimastigote Transformation In Vivo

Kasmera, 2012
Trypanosoma cruzi epimastigogenesis naturally occurs in the intestine of the invertebrate host. It is not known whether the morphological changes that occur during transformation of bloodstream trypomastigotes to epimastigotes are identical for different

Optimizing In Vitro Metacyclogenesis: Strain-Specific Variability in Trypanosoma cruzi Responses to Nutritional and pH Stress

Parasitologia
Metacyclogenesis is a critical process in the Trypanosoma cruzi life cycle. This transition naturally occurs in an insect vector’s gut. Although Triatomine Artificial Urine (TAU) medium is the widely adopted approach to metacyclogenesis in vitro, its ...
