Abstract in Portuguese
As espécies de mamíferos da Magnaordem Xenarthra podem apresentar infecção por diversas espécies de parasitas da Família Trypanosomatidae, incluindo representantes dos gêneros Trypanosoma, Endotrypanum e Leishmania. Além dos Xenarthra, representantes do gênero Coendou (Ordem Rondentia) também foram incluídos neste estudo. Assim, foi possível descrever a diversidade de tripanossomatídeos nos Xenarthra e no gênero Coendou, provenientes principalmente da região Amazônica. As amostras de sangue, tecido e hemoculturas foram coletadas em sua maioria nos estados Pará e Rondônia, seguido do Mato Grosso, Paraíba e Ceará. Análises filogenéticas com a região V7V8 do gene SSU rDNA e do gene gGAPDH, confirmaram a presença de T. rangeli (linhagens A, B e E) em preguiças e tamanduás, T. cruzi (TcIII) em preguiças e tatús, Endotrypanum ssp. em preguiças e Porcisia em ouriços. Além disso, encontramos em todos hospedeiros duas possíveis novas espécies de trypanossomas denominadas de T. sp1 e T. sp2.

Abstract in English
Mammal species of Magnaordem Xenarthra may be infected by several parasitic species of Trypanosomatidae family, including representatives of the genera Trypanosoma, Endotrypanum and Leishmania. In addition to the Xenarthra, representatives of the genus Coendou (Rondentia Order) were also included in this study. Thus, it was possible to describe the diversity of trypanosomatids in the Xenarthra and in the genus Coendou, mainly from the Amazon region. Blood samples, tissue and blood cultures were collected mostly in the states of Pará and Rondônia, followed by Mato Grosso, Paraíba and Ceará. Phylogenetic analyzes based in the V7V8 region of the SSU rDNA and gGAPDH genes confirmed the presence of T. rangeli (lineages A, B and E) in sloths and anteaters, T. cruzi (TcIII) in sloths and armadillos, Endotrypanum ssp. in sloths and Porcisia in porcupine. In addition, we found in all hosts two candidates to a new species of Trypanosoma named herein T. sp1 and T. sp2.
