Trypanosomes can infect humans and animals. This is the first record of the occurrence of Trypanosoma evansi in Rondônia.
Blood samples were collected from 7 dogs and 22 humans. Furthermore, triatomines and tabanids were collected.
It was observed that 42.8% of the dogs tested positive for T. evansi and 14.3% presented mixed infection; 15% of the triatomines tested positive for flagellates identified as T. cruzi TCI (3 specimens), T. cruzi TCI, and T. rangeli (1 specimen), and one with T. cruzi TCV. Two tabanids were infected with T. theileri.
These findings may benefit vector control strategies.
