Microbiomes of North American Triatominae: The Grounds for Chagas Disease Epidemiology
Sonia M. Rodríguez-Ruano,Veronika Skochova,Ryan O. M. Rego,Justin O. Schmidt,Walter Roachell,Václav Hypša,Eva Nováková +6 more
TL;DR: A comparative survey of blood feeding vectors of Triatominae showed that the microbiome composition is determined by host species, rather than locality or environment, and detected considerable changes along the host's ontogeny, including clear trends in the abundance variation of the three dominant bacteria.

TL;DR: This study is the first to demonstrate deterministic patterns in microbiome composition among all life stages and multiple Triatoma species and hypothesise that triatomine microbiome assemblages are produced by species- and life stage-dependent uptake of environmental bacteria and multiple indirect transmission strategies that promote bacterial transfer between individuals.
Microbiomes of North American Triatominae: the grounds for Chagas disease epidemiology

TL;DR: It is shown that the microbiome composition is determined by host species, rather than locality or environment, and there is a trend towards more diverse microbiomes in T. cruzi positive T. protracta specimens.

TL;DR: The vector for Chagas disease is endemic in the southern U.S. as mentioned in this paper, while traditionally thought to only occur in rural habitats and sylvatic transmission cycles, rec...

TL;DR: Current countermeasures used during field training on JBSA appear to be sufficient for preventing autochthonous human Chagas disease.
