Bloodmeal metabarcoding of Triatoma dimidiata from Guatemala

Trypanosoma cruzi, the causative agent of Chagas disease, is primarily
transmitted by triatomine insects, including Triatoma dimidiata. In
Central America, vector control programs have significantly reduced
transmission; however, certain regions, such as Comapa, Jutiapa,
Guatemala, continue to experience persistent T. dimidiata infestation.
Amplicon deep-sequencing analysis from triatomines identified seven
vertebrate species and one insect family as hosts upon which triatomines
have previously fed, with chickens being the most common blood source,
followed by rats, dogs, humans, cats, pigs, ducks, mice, and a genus of
cockroaches.
