Compromiso gastrointestinal por Triypanosoma cruzi: ¿cuándo buscar y cuándo tratar?

Gastroenterol. latinoam; 29 (supl.1), 2018
Chagas disease is an endemic zoonosis that can cause chronic medical complications in a third of those infected, usually decades after infection. It mainly affects the peripheral nervous system of heart, esophagus and colon. At digestive level, motor dysfunction leads to the development of megaesophagus ...

Primer registro de Eratyrus mucronatus Stal, 1859: vector de la enfermedad de Chagas en el departamento del Putumayo, Colombia

MedUNAB; 21 (3), 2018
Sra. Editora, La enfermedad de Chagas, también llamada tripanosomiasis americana, es una enfermedad potencialmente mortal causada por el parásito protozoo Trypanosoma cruzi. Esta enfermedad es un problema de salud pública, ya que se calcula que en el mundo hay entre 6 y 7 millones de personas infectad...

Novel Kdr mutations (K964R and A943V) in pyrethroid resistant populations of Triatoma mazzottii Usinger and Triatoma longipennis Usinger from Mexico and detoxifying enzymes

Insect sci. (Online); 26 (5), 2018
Although having five different ways of transmission the vector-borne is theprincipal way of transmission of Chagas disease, which involves insects of the subfamilyTriatominae (Hemiptera: Reduviidae). Nineteen of the 31 species that occur in Mexico areassociated with humans, and all are capable of transmi...

Models of Disease Vector Control: When Can Aggressive Initial Intervention Lower Long-Term Cost?

Bull. math. biol; 80 (), 2018
Insecticide spraying of housing units is an important control measure for vector-borne infections such as Chagas disease. As vectors may invade both from other infested houses and sylvatic areas and as the effectiveness of insecticide wears off over time, the dynamics of (re)infestations can be approxima...

Efectos de diferentes dosis subletales de deltametrina sobre la inestabilidad en el desarrollo de alas y la eficiencia reproductiva en Triatoma infestans (Hemiptera: Reduviidae, Triatominae)
Effects of differents subletal doses of deltametrina about the instability in wing development and reproductive efficency of Triatoma infestans (Hemiptera: Reduviidae, Triatominae)

El control químico del vector representa la herramienta de mayor importancia para el manejo de la enfermedad de Chagas en zonas endémicas. El rociado con deltametrina se viene realizando desde hace 30 años. Aún así, la efectividad de este compuesto ha disminuido en la última década a causa de la r...

Stage-Dependent Expression of Deltamethrin Toxicity and Resistance in Triatoma infestans (Hemiptera: Reduviidae) From Argentina

J. med. entomol. Suppl; 55 (4), 2018
Triatoma infestans Klug (Hemiptera: Reduviidae) is the main vector of Chagas disease in Latin America. This insect has been controlled with pyrethroids since the 1980s, although the emergence of resistance to deltamethrin has decreased control success in some areas of the Gran Chaco ecoregion. The respon...

Insect cuticle: a critical determinant of insecticide resistance

Intense use of insecticides has resulted in the selection of extreme levels of resistance in insect populations. Therefore understanding the molecular basis of insecticide resistance mechanisms becomes critical. Penetration resistance refers to modifications in the cuticle that will eventually slow down ...

Beating the odds: Sustained Chagas disease vector control in remote indigenous communities of the Argentine Chaco over a seven-year period

Plos negl. trop. dis; 12 (10), 2018
Background: Rapid reinfestation of insecticide-treated dwellings hamper the sustained elimination of Triatoma infestans, the main vector of Chagas disease in the Gran Chaco region. We conducted a seven-year longitudinal study including community-wide spraying with pyrethroid insecticides combined with pe...

Perfil hematológico e bioquímico de pacientes com doença de Chagas atendidos por um serviço de atenção farmacêutica no estado do Ceará

Introdução: A doença de Chagas (DC) é uma parasitose causada pelo agente infeccioso Trypanosoma cruzi. No Brasil, o tratamento específico da DC é realizado com o Benzonidazol (Bz), que devido à sua toxicidade pode levar ao aparecimento de várias reações adversas aos pacientes que fazem uso dest...
