Entomological surveillance of Trypanosoma cruzi vectors in Rio Grande do Norte, Brazil

Medical and Veterinary Entomology, EarlyView.
Discontinuous entomological surveillance and persistent infestation by triatomines highlight the risk of Trypanosoma cruzi transmission. The diversity of triatomine species in the peridomicile shows the potential for colonization into the home. The wide distribution of Triatoma brasiliensis and Triatoma pseudomaculata accompanies high rates of ...

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 ...

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.

Human immune response to triatomine embryo extract [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 1997
Dipetalogaster maximus embryo extracts were used to stimulate peripheral blood mononuclear cells (PBMC) and in ELISA with sera either from Trypanosoma cruzi infected or non-infected individuals. The results showed that there was significant proliferative response and high antibody titers in sera of chagasic patients.

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

High Spatial Resolution Ensemble Species Distribution Modeling of Rhodnius prolixus, Vector of Chagas Disease, in Western Venezuela

GeoHealth, Volume 10, Issue 5, May 2026.
Abstract Rhodnius prolixus is the most common and abundant kissing bug found in Royal and other native palms from western Venezuela. R. prolixus is a dominant vector of Trypanosoma cruzi, the parasite causing Chagas disease. Here we use species distribution models (SDMs) to estimate habitat suitability for R. prolixus.

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review

Chemical Biology &Drug Design, Volume 107, Issue 5, May 2026.
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...

Exploiting triatomine behaviour: alternative perspectives for their control [PDF]

Memórias do Instituto Oswaldo Cruz, 2009
Living in close association with a vertebrate host and feeding on its blood requires different types of adaptations, including behavioural adjustments. Triatomines exhibit particular traits associated with the exploitation of their habitat and food sources and these traits have been the subject of intense analysis.

Screening for Trypanosoma cruzi infection (Chagas disease) in the Latin American population living with HIV in London

HIV Medicine, Volume 27, Issue 5, Page 796-802, May 2026.
Abstract Background There are an estimated 2482 people born in Latin American countries receiving care for HIV in the United Kingdom. Although national guidance recommends screening for Trypanosoma cruzi infection (Chagas disease) in this population, there is no formal screening programme.

Genetic variability in Brazilian triatomines and the risk of domiciliation [PDF]

Memórias do Instituto Oswaldo Cruz, 1999
Among the 126 Brazilian members of the subfamily Triatominae, those of greatest epidemiological importance include Triatoma infestans, passively introduced into this country from Bolivia through human migrations; Panstrongylus megistus, with a wide distribution in humid forest areas; T.
