A cardiomiopatia chagásica crônica (CCC) é responsável pela maior morbidade e pelo pior prognóstico da doença de Chagas, além de ser a mais fibrosante das cardiopatias. Na doença de Chagas, predizer quais fatores se correlacionam com progressão da doença, morbidade e mortalidade constitui um de...
Selenium is an essential trace element which, at adequate levels, presents different beneficial biological effects, such as cancer regression, tissue development and protection against oxidative damage. The positive effects of this element are related to the expression of selenoproteins and their ability...
The Pharmaceutical Care Service of the Chagas Disease Research Laboratory (LPDC), in the State of Ceará, Brazil, treats patients with Chagas disease (CD), characterized as a chronic, neglected disease that requires full patient follow-up. Objective: determine the socioeconomic and demographic profile of...
Chagas disease affects around 6 million people in the world, and in Latin America, it is mainly transmitted by the kissing bug. Chemical control of the vector with pyrethroid insecticides has been the most frequently used tool to reduce the disease incidence. Failures of field control have been detected ...
Background: Triatomine bugs are responsible for the vectorial transmission of the parasite Trypanosoma cruzi, etiological agent of Chagas disease, a zoonosis afecting 10 million people and with 25 million at risk of infection. Several
triatomine species of the genus Rhodnius have been found inhabiting pa...
One of the stated goals of the London Declaration on Neglected Tropical Diseases is the interruption of domiciliary transmissions of Chagas disease in the region of the Americas. We used a game-theoretic approach to assess the voluntary use of insecticide treated nets (ITNs) in the prevention of the spre...
The aim of this study was to determine imidacloprid’s lethal activity against fifth-instar nymphs of Triatoma infestans. In the first stage of this work, it was assayed the topical application of this insecticide on non-fed and repletion-fed nymphs. Results showed a DL50 three times greater in non-fed ...
Triatoma infestans (Klug) (Hemiptera: Reduviidae) is the main vector of Chagas disease in the Southern Cone of America and resistance to pyrethroid insecticides has been detected in several areas from its geographical distribution. Pyrethroid resistance presents a complex geographical pattern at differen...
The genetic structure of natural populations offers insight into the complexities of their dynamics, information that can be
relevant to vector control strategies. Microsatellites are useful neutral markers to investigate the genetic structure and gene flow
in Triatoma infestans, one of the main vectors ...
In South America, Triatoma infestans (Hemiptera: Reduviidae) is the main vector of the parasite Trypanosoma cruzi, etiological agent of Chagas disease. The main strategy for vector control is to spray domestic structures with pyrethroids. Reports of populations of T. infestans with varying degrees of res...
