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 ...

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.

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

Description of nymphs and ontogenetic morphometry of Triatoma ryckmani Zeledón & Ponce, 1972 (Hemiptera: Heteroptera: Reduviidae: Triatominae)

EntomoBrasilis, 2020
Triatoma ryckmani Zeledón & Ponce, 1972 is a species found in sylvatic habitat at Central America. Considered rare in the past and poorly studied, nowadays can be found inside houses with potential of dispersal and colonization.

Cytokines Gene Expression on Macrophages Exposed to Triatoma Salivary Gland Extracts [PDF]

, 2018
Triatoma sanguisuga and Triatoma Indictiva are vectors of Chagas disease. These two vectors goes to the host and bites down to feed on blood, which is necessary for the egg laying process. The disease however is not spread through their bite, but through

Spermatogenesis in Triatoma melanocephala (Hemiptera: Triatominae).

Genetics and molecular research : GMR, 2014
Triatoma melanocephala is a rare species of Hemiptera. It belonged to the Brasiliensis subcomplex and presents morphological characteristics very close to those of Triatoma vitticeps. We investigated spermatogenesis of T. melanocephala and compared it with that of T.

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

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.
