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

Trypanosoma cruzi prevalence and clinical forms in blood donor candidates in Brazil

Revista de Saúde Pública, 2003
The prevalence and clinical forms of Trypanosoma cruzi were evaluated among blood donor candidates attended at a general hospital in Rio de Janeiro, Brazil, from January 1997 to April 1999.

Histopathologic identification of Trypanosoma cruzi (Chagas') encephalitis in an AIDS patient

Human Pathology: Case Reports, 2017
Trypanosoma cruzi (Chagas') encephalitis is an uncommon manifestation of T. cruzi infection, typically seen in immunocompromised patients. Encephalitis results from the reactivation of chronic infection predominately in individuals from endemic areas ...

Host-Parasite Interactions in Chagas Disease: Genetically Unidentical Isolates of a Single Trypanosoma cruzi Strain Identified In Vitro via LSSP-PCR. [PDF]

PLoS ONE, 2015
The present study aims at establishing whether the diversity in pathogenesis within a genetically diverse host population infected with a single polyclonal strain of Trypanosoma cruzi is due to selection of specific subpopulations within the strain.

Análise da fonte alimentar de Panstrongylus megistus (Hemiptera, Reduviidae, Triatominae) e sua atual importância como vetor do Trypanosoma cruzi, no Estado de Minas Gerais Analysis on the food source of Panstrongylus megistus (Hemiptera, Reduviidae, Triatominae) and its present importance as a vector for Trypanosoma cruzi, in the State of Minas Gerais

Revista da Sociedade Brasileira de Medicina Tropical, 2010
INTRODUÇÃO: A pesquisa da fonte alimentar dos triatomíneos auxilia no conhecimento sobre a biologia destes insetos, inclusive para inferir-se a importância dos mesmos como transmissores do Trypanosoma cruzi ao homem.

Host-parasite interaction: changes in human placental gene expression induced by Trypanosoma cruzi

Parasites & Vectors, 2018
Background Chagas disease is caused by Trypanosoma cruzi, a parasite endemic to Latin America. Most infections occur in children by vector or congenital transmission.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Cytochrome c oxidase subunit 1 gene as a DNA barcode for discriminating Trypanosoma cruzi DTUs and closely related species

Parasites & Vectors, 2017
Background The DNA barcoding system using the cytochrome c oxidase subunit 1 mitochondrial gene (cox1 or COI) is highly efficient for discriminating vertebrate and invertebrate species.

Ruthenium‐Catalyzed CH Alkenylation of Trypanocidal Naphthoquinones: A Mechanistic Benchmarking Study

ChemistryOpen, EarlyView.
Computational roadmap to click‐ready quinones. Quantum chemical analysis reveals how substituents modulate the reactivity of trypanocidal naphthoquinones in Ru‐catalyzed CH alkenylation, guiding the design of sulfonyl‐fluoride scaffolds for next‐generation antiparasitic agents.

High prevalence of Trypanosoma cruzi infection in shelter dogs from southern Louisiana, USA

Parasites & Vectors, 2019
Background Chagas disease is a zoonotic disease caused by the protozoan parasite Trypanosoma cruzi. The role of dogs as sentinels has been proposed in multiple regions, as they are a domestic reservoir for T. cruzi.
