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 ...

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

Memorias 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

Psyche: 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

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.

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

Memorias 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 ...

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

Psyche: 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

The Contribution of Entomological Surveillance to the Control of Chagas Disease in Endemic Regions: An Integrative Literature Review

Tropical Medicine &International Health, Volume 31, Issue 7, Page 832-842, July 2026.
ABSTRACT Chagas disease remains a significant public health challenge in various endemic regions of Latin America. The persistence of vector‐borne transmission highlights the complexity of the issue and the limitations of traditional strategies. In this context, entomological surveillance plays a strategic and multifaceted role, not only in the early ...

Thrombin Inhibitors from Different Animals

BioMed Research International, Volume 2010, Issue 1, 2010., 2010
Venous and arterial thromboembolic diseases are still the most frequent causes of death and disability in high‐income countries. Clinical anticoagulants are inhibitors of enzymes involved in the coagulation pathway, such as thrombin and factor Xa. Thrombin is a key enzyme of blood coagulation system, activating the platelets, converting the fibrinogen ...

Trypanosomes and gut microbiota interactions in triatomine bugs and tsetse flies: A vectorial perspective

Medical and Veterinary Entomology, Volume 38, Issue 3, Page 253-268, September 2024.
Trypanosoma sp. presence modulates or has zero effect on gut microbiota composition. Microbiota presence modulates or has zero effect on Trypanosoma sp. growth. Vector biology of triatomine bugs and tsetse flies influences their gut microbiota composition.
