Abstrakt: Trypanosoma vivaxZiemann is a parasite that affects both wild and domestic ungulates and is transmitted mechanically via tabanids and other blood-sucking insects in the Americas. A total of 621 blood samples from water buffaloes (Bubalus bubalis(Linnaeus) (Artiodactyla: Bovidae), and 184 ectoparasite samples (Amblyomma cajennense(Fabricius) sensu stricto and Rhipicephalus(Boophilus) microplus(Canestrini) (Acari: Ixodidae), and Haematopinus tuberculatus(Burmeister) (Phthiraptera: Haematopinidae)) were obtained from 60 farms in the State of Pará, Brazilian Amazon. Twelve buffalo blood samples (1.89%) and 11 ectoparasites (6%) were positive for T. vivaxbased on the cathepsin L-like gene. All sequences were 99% similar to T. vivaxfrom northeastern Brazil (EU753788) in amplified PCR assays on each of the hosts tested.
