Dinâmica da alimentação e dejeção do Triatoma sordida

Revista da Sociedade Brasileira de Medicina Tropical, 1995
Atualmente, o Triatoma sordida é a espécie de triatomíneo mais capturada no Brasil. Para maior esclarecimento do seu potencial vetorial foi estudada a sua dinâmica de alimentação e dejeções, em comparação com o Triatoma infestans ou outras espécies de ...

Infectivity of Aflagellar Epimastigotes of Trypanosoma caninum in the DH82 Cell Line and Mouse Peritoneal Macrophages

Journal of Parasitology Research, Volume 2025, Issue 1, 2025.
Background:Trypanosoma caninum presents aflagellar and flagellar epimastigote, trypomastigote, and spheromastigote forms in axenic cultures. Attempts to utilize trypomastigote forms of T. caninum to develop in vitro and in vivo infection models have failed. To investigate the infection potential of aflagellar epimastigotes, T.

Control of rural house infestation by Triatoma infestans in the Bolivian Chaco using a microencapsulated insecticide formulation [PDF]

, 2015
Background: Triatoma infestans, the main vector of Trypanosoma cruzi (causative agent of Chagas disease) has been successfully eliminated over much of its original geographic distribution over the southern cone countries of South America.

Associations Between Developmental Stability, Canalization, and Phenotypic Plasticity in Response to Heterogeneous Experience

Ecology and Evolution, Volume 14, Issue 10, October 2024.
Decreased canalization may promote plastic responses in traits before or during the induction of plasticity, whereas canalization may reflect phenotypic convergence after plastic responses. ABSTRACT The processes of developmental stability, canalization, and phenotypic plasticity have ecological and evolutionary significance, and been studied ...

Biological activity of Schinus molle on Triatoma infestans

Fitoterapia, 2006
Hexanic extracts from leaves and fruits of Schinus molle were tested for repellent and insecticidal properties against first instar nymphs and eggs of Triatoma infestans, the vector of Chagas' disease. Leaf and fruit extracts were highly repellent for first nymphs. Fruit extracts had also ovicidal activity.

Modelling the potential geographic distribution of triatomines infected by Triatoma virus in the southern cone of South America [PDF]

, 2015
Background: Triatoma virus (TrV) is the only entomopathogenous virus identified in triatomines. We estimated the potential geographic distribution of triatomine species naturally infected by TrV, using remotely sensed and meteorological environmental ...

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.

Metaciclogênese do Trypanosoma cruzi como parâmetro de interação do parasita com o triatomíneo vetor

Revista da Sociedade Brasileira de Medicina Tropical, 1997
Triatoma infestans infectados por três amostras do Trypanosoma cruzi permitiram observar: 1) variabilidade numérica de metacíclicos obtidos de cada amostra após diferentes períodos de infecção; 2) diferenças na perda da infecção de acordo com a amostra ...

Antennal Phenotype of Triatoma dimidiata Populations and Its Relationship with Species of phyllosoma and protracta Complexes [PDF]

, 2005
Triatoma dimidiata (Latreille 1811) Reduviidae Triatominae is the main vector of Chagas disease in several countries of Latin America. As for other vector species, the characterization of T. dimidiata subpopulations within particular geographical regions

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 ...
