The Contribution of Entomological Surveillance to the Control of Chagas Disease in Endemic Regions: An Integrative Literature Review

Tropical Medicine &International Health, EarlyView.
ABSTRACT Chagas disease remains a significant public health challenge in various endemic regions of Latin America. The persistence of vector‐borne transmission highlights the complexity of the issue and the limitations of traditional strategies. In this context, entomological surveillance plays a strategic and multifaceted role, not only in the early ...

Blood meal sources of wild and domestic Triatoma infestans (Hemiptera : Reduviidae) in Bolivia : connectivity between cycles of transmission of Trypanosoma cruzi [PDF]

, 2016
Background: Chagas disease is a major public health problem in Latin America. Its etiologic agent, Trypanosoma cruzi, is mainly transmitted through the contaminated faeces of blood-sucking insects called triatomines. Triatoma infestans is the main vector

Chagas disease in Canadian blood donors: 15 years of selective testing

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Chagas disease (Trypanosoma cruzi), prevalent in Mexico, Central and South America, can be transfusion‐transmitted. Selective serological testing of blood donors was implemented over 15 years ago. We describe the trends in infections and characteristics of donors selected for testing.

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.

TNF‐α partially modulates the endothelial dysfunction during the acute phase of Trypanosoma cruzi infection

British Journal of Pharmacology, Volume 183, Issue 10, Page 2256-2272, May 2026.
Background and Purpose Whereas the effects of Trypanosoma cruzi (T. cruzi) infection are well‐characterised in the heart, its impact on the vasculature has received little attention. In this study, we investigated the effects of acute and chronic T. cruzi infection on vascular responsiveness and the underlying mechanisms.

Survey of the Reduviidae (Heteroptera) of Southern Illinois, Excluding the Phymatinae, With Notes on Biology [PDF]

, 2018
A survey of the nonphymatine reduviids of southern Illinois was con­ducted from April 1996 to November 1998. In addition to county distributions, information was collected on times of occurrence of adults and nymphs and associated habitats.
