All Roads Lead to Cytosol: Trypanosoma cruzi Multi-Strategic Approach to Invasion
Frontiers in Cellular and Infection Microbiology, 2021 T. cruzi has a complex life cycle involving four developmental stages namely, epimastigotes, metacyclic trypomastigotes, amastigotes and bloodstream trypomastigotes.

Memorias do Instituto Oswaldo Cruz, 2003 Amastigogenesis occurs first when metacyclic trypomastigotes from triatomine urine differentiate into amastigotes inside mammalian host cells and a secondary process when tissue-derived trypomastigotes invade new cells and differentiate newly to ...

Development of an aptamer-based concentration method for the detection of Trypanosoma cruzi in blood. [PDF]
PLoS ONE, 2012 Trypanosoma cruzi, a blood-borne parasite, is the etiological agent of Chagas disease. T. cruzi trypomastigotes, the infectious life cycle stage, can be detected in blood of infected individuals using PCR-based methods.

Infectivity of amastigotes of Trypanosoma cruzi
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.

Trypanosoma cruzi trypomastigotes induce cytoskeleton modifications during HeLa cell invasion
Memorias do Instituto Oswaldo Cruz, 2011 It has been recently shown that Trypanosoma cruzi trypomastigotes subvert a constitutive membrane repair mechanism to invade HeLa cells. Using a membrane extraction protocol and high-resolution microscopy, the HeLa cytoskeleton and T.

Transcriptional remodeling during metacyclogenesis in Trypanosoma cruzi I
Virulence, 2020 Metacyclogenesis is one of the most important processes in the life cycle of Trypanosoma cruzi. In this stage, noninfective epimastigotes become infective metacyclic trypomastigotes.

Surface antigens of metacyclic trypomastigotes of Trypanosoma cruzi [PDF]
Infection and Immunity, 1983 The surface antigen makeup of metacyclic trypomastigote forms of strain G of Trypanosoma cruzi, which produce a subpatent infection in mice, differed from those of the virulent strains Y and CL. A 100,000-molecular-weight protein, barely detectable on the Y or CL cell surface, appeared as the main surface antigen of the G metacyclic trypomastigotes. In

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies
Journal of Applied Entomology, EarlyView.ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.
