Insights from tissue-specific transcriptome sequencing analysis of Triatoma infestans

Mem. Inst. Oswaldo Cruz; 112 (6), 2017
ABSTRACT Triatoma infestans is an insect of subfamily Triatominae (Hemiptera: Reduviidae) and an important vector of Trypanosoma cruzi, the etiologic agent of human Chagas disease. In this work we reported a transcriptome assembly and annotation of T. infestans heads obtained by Next Generation Sequencin...

¿Qué dicen los números de la evolución temporal de la enfermedad de Chagas?

Rev. chil. infectol; 34 (2), 2017
Chagas disease remains highly prevalent in Chile, especially between the regions of Arica and Parinacota, and Coquimbo. Since 1999 it is considered that in Chile the vector transmission was interrupted. Under this premise, the epidemiological dynamics should be changing. We analyzed the evolution of the ...

Mosquitoes (Diptera: Culicidae) from crepuscular period in an Atlantic Forest area in Southern Brazil

Spatial-temporal analysis of dengue deaths: identifying social vulnerabilities

Abstract: INTRODUCTION Currently, dengue fever, chikungunya fever, and zika virus represent serious public health issues in Brazil, despite efforts to control the vector, the Aedes aegypti mosquito. METHODS: This was a descriptive and ecological study of dengue deaths occurring from 2002 to 2013 in S...

The development of Panstrongylus herreri under fluctuating environmental conditions

Abstract: INTRODUCTION: Panstrongylus herreri is a main Chagas disease vector, and its success as a vector stems from its ability to establish domiciliated colonies; we aimed to explore its biology and reproduction. METHODS: The average amount of blood ingested and the time from the beginning of a blo...
