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.

Astrocyte Apoptosis and HIV Replication Are Modulated in Host Cells Coinfected with Trypanosoma cruzi [PDF]

, 2017
The protozoan Trypanosoma cruzi is the etiological agent of Chagas disease. In immunosuppressed individuals, as it occurs in the coinfection with human immunodeficiency virus (HIV), the central nervous system may be affected. In this regard, reactivation

ROS and Trypanosoma cruzi: Fuel to infection, poison to the heart

PLoS Pathogens, 2018
The activation of macrophage respiratory burst in response to infection with Trypanosoma cruzi inflicts oxidative damage to the host’s tissues. For decades, the role of reactive oxygen species (ROS) in the elimination of T.

Revisiting the Trypanosoma cruzi metacyclogenesis: morphological and ultrastructural analyses during cell differentiation

Parasites & Vectors, 2018
Trypanosoma cruzi uses several strategies to survive in different hosts. A key step in the life-cycle of this parasite is metacyclogenesis, which involves various morphological, biochemical, and genetic changes that induce the differentiation of non ...

Structural organization of Trypanosoma cruzi [PDF]

Memórias do Instituto Oswaldo Cruz, 2009
Since the initial description of Trypanosoma cruzi by Carlos Chagas in 1909, several research groups have used different microscopic techniques to obtain detailed information about the various developmental stages found in the life cycle of this intracellular parasite.

Canine Trypanosoma cruzi infection in the Bolivian Chaco [PDF]

, 2018
A cross-sectional study on Trypanosoma cruzi was carried out in 2013 to evaluate the role of dogs as possible source of infection for humans in two rural communities of the highly endemic Bolivian Chaco (Bartolo, Chuquisaca Department, n = 57 dogs; and ...

Spontaneous dormancy protects Trypanosoma cruzi during extended drug exposure

bioRxiv, 2017
The ability of the Chagas disease agent Trypanosoma cruzi to resist extended in vivo exposure to highly effective trypanocidal compounds prompted us to explore the potential for dormancy and its contribution to failed drug treatments in this infection ...
