摘要：

The main effects of trypanosomosis in Brazil are related to reproductive alterations. In this context, the present study aimed to report the occurrence of abortions in goats and sheeps in the semiarid region of Northeastern Brazil, associated with Trypanosoma vivax. Trypomastigotes forms visualized by Buffy coat technique (BCT) method in 68.7% of the goats and 50.0% of the ewes that aborted. PCR identified that 100% of the goats and ewes that aborted were infected with T. vivax. The goats and ewes that aborted showed high parasitemia and developed clinical signs of trypanosomosis. The presence of T. vivax DNA was identified in the blood of fetuses by the PCR technique, proving infection by T. vivax in aborted fetuses, as well as confirming the congenital transmission of the parasite.
