Anti-Trypanosoma cruzi action of a new benzofuran derivative based on amiodarone structure [PDF]

, 2018
Chagas disease is a neglected tropical affection caused by the protozoan parasite Trypanosoma cruzi. There is no current effective treatment since the only two available drugs have a limited efficacy and produce side effects.

A new piece in the repeatome puzzle of Triatominae bugs: The analysis of Triatoma rubrofasciata reveals the role of satellite DNAs in the karyotypic evolution of distinct lineages

Insect Molecular Biology, Volume 34, Issue 6, Page 917-928, December 2025.
Satellite DNAs comprise the major component of the Triatoma rubrofasciata repeatome, highlighting their central role in genome composition and architecture. Satellite DNA families show recent amplification in heterochromatin and older, more divergent satellite DNAs located in euchromatin, indicating distinct evolutionary histories.

Identification and characterization of the causative triatomine bugs of anaphylactic shock in Zhanjiang, China

Infectious Diseases of Poverty, 2018
Background Two health concerns primarily related to triatomine bugs are transmission of Trypanosoma cruzi through infective feces, and allergic reactions induced by triatomine bites.

Phylogenetic multi-locus codon models and molecular clocks reveal the monophyly of haematophagous reduviid bugs and their evolution at the formation of South America.

, 2010
We previously constructed a single molecular clock to date insect evolution that remains a cornerstone within entomological dating. The insect clock predicts that triatomine bugs, the vectors of South American trypanosomiasis, originated with the ...

Systemic insecticide treatment of the canine reservoir of Trypanosoma cruzi induces high levels of lethality in Triatoma infestans, a principal vector of Chagas disease [PDF]

, 2017
BACKGROUND: Despite large-scale reductions in Chagas disease prevalence across Central and South America, Trypanosoma cruzi infection remains a considerable public health problem in the Gran Chaco region

Potential geographic displacement of Chagas disease vectors under climate change

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 709-717, December 2025.
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...

Bacterial community composition in the salivary glands of triatomines (Hemiptera: Reduviidae). [PDF]

PLoS Neglected Tropical Diseases, 2018
BACKGROUND:Chagas disease is caused by the parasite Trypanosoma cruzi and is transmitted through triatomines (Hemiptera: Reduviidae). In the last year, many studies of triatomine gut microbiota have outlined its potential role in modulating vector ...

Prevention and control of Chagas Disease : an overview [PDF]

, 2018
Chagas disease is the main cause of heart failure and sudden death in the Western Hemisphere. The literature of the last decades reported on the changing epidemiological profiles of Chagas disease, which now threats the human population in the cities ...

Automated identification of spotted‐fever tick vectors using convolutional neural networks

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 829-841, December 2025.
We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Spermatogenesis and nucleolar activity in Triatoma klugi (triatomine, Heteroptera) [PDF]

Genetics and Molecular Biology, 2008
Triatoma klugi is a Chagas disease vector in the Rio Grande do Sul State. Triatominae chromosomes are holocentric and sex chromosomes segregation is post-reductional. In this paper we describe the karyotype of male T. klugi and a meiotic analysis including the nucleolar behavior during spermatogenesis.
