ABSTRACT Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Colombia, 437 000 people are infected with T. cruzi, of whom 131 00...
Background Major drawbacks of the available treatment against Chagas disease (American trypanosomiasis) include its toxicity and therapeutic inefficiency in the chronic phase of the infection, which makes it a concern among neglected diseases. Therefore, the discovery of alternative drugs for treating c...
Background The present study evaluated the effect of treatment with benznidazole on mRNA expression of IFN-γ, IL-17, IL-10, TGF-β and FoxP3 in spleen and heart tissue of BALB/c mice in the acute phase of an experimental infection with Trypanosoma cruzi, strains JLP or Y. Methods The mRNA expre...
Environmentally-induced developmental instability has frequently been assessed using fluctuating asymmetry (FA) methods. For Triatoma infestans, the major vector of Chagas disease, the combined effects of host-feeding sources and habitats affected wing developmental instability depending on sex in Figuer...
A wide range of insecticide resistance profiles has been reported across Bolivian domestic and sylvatic populations of Triatoma infestans (Klug, 1834) (Hemiptera, Reduviidae), including some with levels proven to be a threat for vector control. In this work, the insecticide profile of domestic T. infesta...
Triatomines are blood-sucking bugs that occur mainly in Latin America. They are vectors of Trypanosoma cruzi, the parasite that causes Chagas disease. Chemical control of Chagas disease´s vectors by using pyrethroid insecticides has been highly successful for the elimination of domestic infestation and ...
Chagas disease is caused by the parasite Trypanosoma cruzi and transmitted by multiple triatomine vectors across the Americas. In Central America, the predominant vector is Triatoma dimidiata, a highly adaptable and genetically diverse Hemiptera. In this research, we used a novel reduced-representation D...
While long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) are the cornerstones of malaria vector control throughout sub-Saharan Africa, there is an urgent need for the development of novel insecticide delivery mechanisms to sustain and consolidate gains in disease reduction and to t...
Diversos trabalhos foram realizados ao longo da história do Brasil com o intuito de se controlar e erradicar os bichos barbeiros do ambiente habitado por seres humanos, incluindo a realização de controle químico com hexaclorociclohexanos. O objetivo desta pesquisa foi avaliar a ...
We investigated the dynamics and underlying causes of house (re)infestation with Triatoma infestans (Klug 1834) after a community-wide residual spraying with pyrethroids in a well-defined rural section of Pampa del Indio municipality (northeastern Argentina) over a 4-yr period. House infestation was asse...
