Biologic and Genetics Aspects of Chagas Disease at Endemic Areas

open access: yesJournal 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 ...

Estudos anatômicos e histológicos sôbre a subfamília Triatominae (Heteroptera, Reduviidae): Parte XXI. Estudo comparado do sistema traqueal em Triatoma, Panstrongylus e Rhodnius

open access: yesMemorias do Instituto Oswaldo Cruz, 1965
É feito um estudo comparado do sistema traqueal nos Triatomíneos. Notou-se que os ramos traqueais secundários apresentam diversidades quanto quanto ao número e à disposição topográfica das traquéias, inclusive quando se tratando de um mesmo exemplar ...

An Insight into the Sialomes of Bloodsucking Heteroptera

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Saliva of bloodsucking arthropods contains dozens or hundreds of proteins that affect their hosts′ mechanisms against blood loss (hemostasis) and inflammation. Because acquisition of the hematophagous habit evolved independently in several arthropod orders and at least twice within the true bugs, there is a convergent evolutionary scenario that creates

Molecular cytotaxonomy of the Triatoma brasiliensis species subcomplex (Hemiptera, Triatominae)

open access: yesActa Tropica, 2020
The Triatoma genus is paraphyletic, and its species are grouped into complexes and subcomplexes. Given the fact that species that make up a given subcomplex generally share chromosomal traits, we analyzed the distribution of AT- and CG-rich DNA of the T.

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

open access: yesJournal 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.

Estudos sobre epidemiologia da doença de Chagas no Ceará VII - suscetibilidade de Triatomíneos a diversas cepas locais de Trypanosoma cruzi

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 1977
Foram isoladas duas cepas de Trypanosoma cruzi de marsupiais de área não endêmica e três cepas de área endêmica: uma de homem, uma de marsupial e uma de cão.

Estudo comparado do ciclo evolutivo de triatomíneos a duas temperaturas Comparison of life cycles of triatominae according to changes in temperature

open access: yesMemorias do Instituto Oswaldo Cruz, 1989
We studied the life cicle of several triatominae species: Dipetalogaster maximus (Uhler, 1894); Panstrongylus herreri Wygodzinsky, 1948; Panstrongylus megistus (Burmeister, 1835); Rhodnius ecuadoriensis Lent & Leon, 1958; Rhodnius nasutus Stal, 1859 ...

Flight dispersal of the Chagas disease vectors Triatoma brasiliensis and Triatoma pseudomaculata in northeastern Brazil

open access: yesActa Tropica, 2007
The present paper reports for the first time the capture of wild Triatoma brasiliensis and Triatoma pseudomaculata by means of light traps in Brazil. We tested commercially available lighting devices powered by batteries to attract the bugs to a white piece of cloth in the field.

The Sexual Behaviour of Chagas′ Disease Vectors: Chemical Signals Mediating Communication between Male and Female Triatomine Bugs

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Chemical communication mechanisms that mediate sexual behaviour in triatomine bugs are reviewed with regard to source, identity, and function of sex pheromones. Males attempt to copulate but may be rejected, depending on female age and nutritional status. Triatomine males locate partners through sex pheromones emitted by the metasternal glands (MGs) of

Performance of yeast-baited traps with Triatoma sordida, Triatoma brasiliensis, Triatoma pseudomaculata, and Panstrongylus megistus in laboratory assays

open access: yesRevista Panamericana de Salud Pública, 2000
The effectiveness of a trap for triatomines baited with yeast cultures has been previously demonstrated for Triatoma infestans in laboratory assays. We report here results from laboratory assays testing yeast traps for Triatoma sordida, Triatoma brasiliensis, Triatoma pseudomaculata, and Panstrongylus megistus.
