Cuticular hydrocarbons of triatomines [PDF]
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007 Triatomine insects (Hemiptera) are the vectors of Chagas disease. Their cuticular surface is covered by a thin layer of lipids, mainly hydrocarbons, wax esters, fatty alcohols, and free or esterified fatty acids. These lipids play a major role in preventing a lethal desiccation, altering the absorption of chemicals and microorganism penetration, they ...

The Neglected Virome of Triatomine Insects [PDF]
Frontiers in Tropical Diseases, 2022 The Triatominae subfamily (Reduviidae) harbors some hematophagous insect species that have been firmly connected to the transmission of Trypanosoma cruzi, the causative agent of Chagas disease. Triatomines not only host and transmit trypanosomatids, but also coexist with a variety of symbiotic microorganisms that generally reside in the insect’s ...

The Role of DmCatD, a Cathepsin D-Like Peptidase, and Acid Phosphatase in the Process of Follicular Atresia in Dipetalogaster maxima (Hemiptera: Reduviidae), a Vector of Chagas' Disease [PDF]
, 2015 In this work, we have investigated the involvement of DmCatD, a cathepsin D-like peptidase, and acid phosphatase in the process of follicular atresia of Dipetalogaster maxima, a hematophagous insect vector of Chagas' disease. For the studies, fat bodies,

Frontiers in Cellular and Infection Microbiology, 2021 Rhodnius neglectus is a potential vector of Trypanosoma cruzi (Tc), the causative agent of Chagas disease. The salivary glands (SGs) and intestine (INT) are actively required during blood feeding. The saliva from SGs is injected into the vertebrate host,

Acute Chagas Disease Manifesting as Orbital Cellulitis, Texas, USA
Emerging Infectious Diseases, 2021 We report a case of acute, vectorborne Chagas disease, acquired locally in central Texas, USA, manifesting as Romaña’s sign, which was initially mistaken for orbital cellulitis.

Pathogens, 2023 Chagas disease is caused by the hemoflagellate protozoan Trypanosoma cruzi. The main transmission mechanism for the parasite in endemic areas is contact with the feces of an infected triatomine bug. Part of the life cycle of T.

Sylvatic triatominae: a new challenge in vector control transmission
Memorias do Instituto Oswaldo Cruz, 2009 Over the last 10 years, Uruguay, Chile and Brazil have been certified as being free from disease transmission by Triatoma infestans, the main domiciliated vector for Chagas disease in the Southern Cone countries.

High Parasitic Loads Quantified in Sylvatic Triatoma melanica, a Chagas Disease Vector
Pathogens, 2022 Triatoma melanica is a sylvatic vector species in Brazil. In We aimed to characterize the Trypanosoma cruzi discrete typing units (DTUs), the parasitic loads, and the blood meal sources of insects collected in rocky outcrops in rural areas in the state ...

Field trials of an improved cost-effective device for detecting peridomestic populations of Triatoma infestans (Hemiptera: Reduviidae) in rural Argentina [PDF]
, 2002 An improved device for detecting peridomestic Triatoma infestans consisting of one-liter recycled Tetra Brik milk boxes with a central structure was tested using a matched-pair study design in two rural areas in Argentina.
