The Pharmacopea within Triatomine Salivary Glands.

Trends in Parasitology, 2020
Triatomines are blood-feeding insects that prey on vertebrate hosts. Their saliva is largely responsible for their feeding success. The triatomine salivary content has been studied over the past decades, revealing multifunctional bioactive proteins ...

Triatomine physiology in the context of trypanosome infection

Journal of Insect Physiology, 2017
Triatomines are hematophagous insects that feed on the blood of vertebrates from different taxa, but can occasionally also take fluids from invertebrate hosts, including other insects. During the blood ingestion process, these insects can acquire diverse parasites that can later be transmitted to susceptible vertebrates if they complete their ...

Preliminary Characterization of Triatomine Bug Blood Meals on the Island of Trinidad Reveals Opportunistic Feeding Behavior on Both Human and Animal Hosts

Tropical Medicine and Infectious Disease, 2020
Chagas disease is a neglected tropical disease caused by infection with Trypanosoma cruzi. The parasite is endemic to the Americas, including the Caribbean, where it is vectored by triatomine bugs.

Triatomine and Trypanosoma cruzi discrete typing units distribution in a semi-arid area of northeastern Brazil.

Acta Tropica, 2021
The occurrence of triatomine species, their bloodmeal sources, and the discrete typing units (DTUs) of Trypanosoma cruzi isolated from them were determined in different municipalities of the state of Rio Grande do Norte, Brazil.

Insecticide Resistance in Triatomines

2021
The control of Chagas disease vectors has been based principally on spraying dwellings with insecticides. This strategy reduced the geographic range and infestation prevalence of major vectors leading to the interruption of disease transmission in several areas from endemic regions.

Resisting an invasion: A review of the Triatomine vector (Kissing bug) defense strategies against a Trypanosoma sp infection.

Acta Tropica, 2022
Triatomines are an important group of insects in the Americas. They serve as transmission vectors for Trypanosoma cruzi, the etiologic agent responsible for the deadly Chagas disease in humans. The digenetic parasite has a complex life cycle, alternating

Analysis of over 1500 triatomine vectors from across the US, predominantly Texas, for Trypanosoma cruzi infection and discrete typing units

Infection, Genetics and Evolution, 2018
Across the Americas, triatomine insects harbor diverse strains of Trypanosoma cruzi (T. cruzi), agent of Chagas disease. Geographic patterns of vector infection and parasite strain associations, especially in vectors encountered by the public, may be ...

Susceptibility dynamics between five Trypanosoma cruzi strains and three triatomine (Hemiptera: Reduviidae) species

Journal of Vector Ecology, 2021
: American trypanosomiasis is a zoonosis caused by the parasite Trypanosoma cruzi and is transmitted mainly by blood-sucking insects belonging to the subfamily Triatominae.

Sensory Biology of Triatomines

2021
Sensory systems mediate behaviors such as food, mate and shelter search, habitat selection, avoidance of environmental risks, escape from predators, and communication with conspecifics. Yet, immersed in an environment full of flowing information, triatomines, as other living organisms, must recognize and make use of adequate and sparse sensory stimuli.

The Immune System of Triatomines

2021
All insects rely on an innate immune system to eliminate potentially lethal parasites and pathogens. In kissing bugs, this immune system comprises a plethora of elements that first recognize parasites and pathogens as non-self, followed by a multi-faceted response to eliminate them.
