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.

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 ...

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

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 ...

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 metasternal and Brindley's Glands of Triatoma brasiliensis Neiva (Hemiptera: Reduviidae) [PDF]

Neotropical Entomology, 2009
Triatoma brasiliensis Neiva is the most important vector of the Chagas' disease in the semiarid zones of North-eastern Brazil. Adult bugs have two main pairs of exocrine glands, the metasternal and the Brindley's glands, which release volatiles possibly with defense, alarm and/or mating functions.

Potential of extracellular vesicles in the pathogenesis, diagnosis and therapy for parasitic diseases

Journal of Extracellular Vesicles, Volume 13, Issue 8, August 2024.
Abstract Parasitic diseases have a significant impact on human and animal health, representing a major hazard to the public and causing economic and health damage worldwide. Extracellular vesicles (EVs) have long been recognized as diagnostic and therapeutic tools but are now also known to be implicated in the natural history of parasitic diseases and ...

Studies in search of a suitable experimental insect model for xenodiagnosis of hosts with Chagas' disease. 1 - Comparative xenodiagnosis with nine triatomine species of animals with acute infections by Trypanosoma cruzi

Memorias do Instituto Oswaldo Cruz, 1982
In search of a suitable vector species for xenodiagnosis of humans and animals with chronic Chagas' disease we first investigated the reactions of different vector species to acute infection with Trypanosoma cruzi.
