Point fill color indicates pool membership. Pools composed of T. cruzi-positive samples are outlined in black. Arrows indicate pools presenting cytb DNA from the T. cruzi reservoir species D. marsupialis and D. novemcinctus. Numbers in parentheses indicate the number of pools in which the corresponding vertebrate blood source was detected.
