Interaction of Trypanosoma cruzi, Triatomines and the Microbiota of the Vectors—A Review [PDF]

Microorganisms
This review summarizes the interactions between Trypanosoma cruzi, the etiologic agent of Chagas disease, its vectors, triatomines, and the diverse intestinal microbiota of triatomines, which includes mutualistic symbionts, and highlights open questions.

Wide distribution of Trypanosoma cruzi-infected triatomines in the State of Bahia, Brazil [PDF]

Parasites & Vectors, 2019
Background The identification of Trypanosoma cruzi and blood-meal sources in synanthropic triatomines is important to assess the potential risk of Chagas disease transmission. We identified T.

Occurrence of triatomines (Hemiptera, Reduviidae) and their natural infection by Trypanosoma cruzi (Chagas, 1909) in Boca do Moa community, Cruzeiro do Sul, Acre, Brazil

Revista da Sociedade Brasileira de Medicina Tropical, 2021
INTRODUCTION: Triatomines are insect vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. METHODS: Triatomines were collected from households and by dissecting palm trees in the peri-urban areas of Cruzeiro do Sul (Acre); they were ...

Effect of habitat fragmentation on rural house invasion by sylvatic triatomines: A multiple landscape-scale approach.

PLoS Neglected Tropical Diseases, 2021
After the decrease of the relative importance of Triatoma infestans, a number of studies reported the occurrence of sylvatic triatomines dispersing actively to domestic environments in the dry western Chaco Region of Argentina.

What happens when the insecticide does not kill? A review of sublethal toxicology and insecticide resistance in triatomines [PDF]

Medical and Veterinary Entomology
Chagas disease is considered one of the most important human parasitosis in the United States. This disease is mainly transmitted by insects of the subfamily Triatominae.

The Role of Bacterial Symbionts in Triatomines: An Evolutionary Perspective

Microorganisms, 2020
Insects have established mutualistic symbiotic interactions with microorganisms that are beneficial to both host and symbiont. Many insects have exploited these symbioses to diversify and expand their ecological ranges.

Detailed ecological associations of triatomines revealed by metabarcoding and next-generation sequencing: implications for triatomine behavior and Trypanosoma cruzi transmission cycles [PDF]

Scientific Reports, 2018
Trypanosoma cruzi is the agent of Chagas disease, transmitted by hematophagous triatomine vectors. Establishing transmission cycles is key to understand the epidemiology of the disease, but integrative assessments of ecological interactions shaping ...

Identification of bloodmeal sources of triatomines captured in the Paraguayan Chaco region of South America by means of molecular biology analysis

Pathogens and Global Health, 2020
The Paraguayan Chaco is an isolated environment with its own unique ecosystem. In this region, Chagas disease remains a health problem. Chagas disease is caused by the parasite Trypanosoma cruzi, and it is primarily transmitted by triatomines.

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 ...
