Evolutionary ecology of Chagas disease; what do we know and what do we need?

Evolutionary Applications, Volume 11, Issue 4, Page 470-487, April 2018., 2018
Abstract The aetiological agent of Chagas disease, Trypanosoma cruzi, is a key human pathogen afflicting most populations of Latin America. This vectorborne parasite is transmitted by haematophageous triatomines, whose control by large‐scale insecticide spraying has been the main strategy to limit the impact of the disease for over 25 years.

Triatomíneos: ação ovicida de alguns piretróides Triatomine: ovicida action of some pyretroids

Revista da Sociedade Brasileira de Medicina Tropical, 2002
A ação ovicida dos inseticidas tem sido pouco considerada nas atividades de controle dos transmissores da endemia chagásica. No sentido de comparar o potencial ovicida de três piretróides sintéticos (lambdacialotrina, alphacipermetrina e deltametrina ...

Immunomodulation by Trypanosoma cruzi: Toward Understanding the Association of Dendritic Cells with Infecting TcI and TcII Populations

Journal of Immunology Research, Volume 2014, Issue 1, 2014., 2014
Dendritic cells (DCs) are major immune components, and depending on how these cells are modulated, the protective host immune response changes drastically. Trypanosoma cruzi is a parasite with high genetic variability and modulates DCs by interfering with their capacity for antigen recognition, migration, and maturation.

Mitochondrial PCR‐RFLP Assay to Distinguish Triatoma brasiliensis macromelasoma from Triatoma brasiliensis brasiliensis Subspecies (Hemiptera: Reduviidae)

Journal of Tropical Medicine, Volume 2013, Issue 1, 2013., 2013
Triatoma brasiliensis sensu lato (s.l.), the main vector of Chagas disease in northeastern Brazil, is a species complex comprising four species, one with two subspecies (T. brasiliensis brasiliensis, T. brasiliensis macromelasoma, T. juazeirensis, T. sherlocki, and T. melanica), and each taxon displaying distinct ecological requirements.

Biologic and Genetics Aspects of Chagas Disease at Endemic Areas

Journal of Tropical Medicine, Volume 2012, Issue 1, 2012., 2012
The etiologic agent of Chagas Disease is the Trypanosoma cruzi, transmitted through blood‐sucking insect vectors of the Triatominae subfamily, representing one of the most serious public health concerns in Latin America. There are geographic variations in the prevalence of clinical forms and morbidity of Chagas disease, likely due to genetic variation ...

Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae) [PDF]

, 2006
Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and

Geographic Distribution of Chagas Disease Vectors in Brazil Based on Ecological Niche Modeling

Journal of Tropical Medicine, Volume 2012, Issue 1, 2012., 2012
Although Brazil was declared free from Chagas disease transmission by the domestic vector Triatoma infestans, human acute cases are still being registered based on transmission by native triatomine species. For a better understanding of transmission risk, the geographic distribution of Brazilian triatomines was analyzed.
