Implication

This research demonstrates that DNA metabarcoding identifies blood-feeding mammal hosts in leishmaniasis vectors, indicating diverse potential sources of infection.

Key Points

The study aims to identify vertebrate hosts of phlebotomine sand flies using invertebrate-derived DNA from blood-feeding vectors of leishmaniasis.
Utilized DNA metabarcoding and next generation sequencing (NGS) to analyze gut content of sand flies.
Collected female phlebotomine sand flies in the Cacao Region of Southeastern Bahia, Brazil, an endemic zone for American Tegumentary Leishmaniasis.
Examined three mitochondrial markers to determine vertebrate hosts and assigned taxonomic units using GenBank NCBI reference databases.
Identified twenty vertebrate operational taxonomic units, including mammals, reptiles, and amphibians.
Detected bloodmeal hosts such as primates, rodents, ungulates, a domestic dog, and a chicken.
Successfully used metabarcoding to sample diverse bloodmeals from sand flies.
