Chagas disease is caused by the protozoan parasite Trypanosome cruzi and can cause both acute and chronic infections in humans, who most often catch the disease from the bits of infected T. dimidiata. A better understanding is needed of the complex interactions between the human host, the T. cruzi parasite, the T. dimidiata vector, and other microbes that reside in the guts of the vector.

In the new work, Sara Helms Cahan, of the University of Vermont, USA, and colleagues studied 61 adult T. dimidiata which had been previously collected throughout Central America from 1999 through 2013. The researchers isolated DNA from the abdomens or legs of each preserved specimen and sequenced the genetic material, which represented a mixture of T. dimidiata DNA as well as DNA from any vertebrate blood meals...
