We report the first detection of Trypanosoma vivax in Bahia state based on blood smear and PCR analyses. A total of 623 bovine blood samples were collected over two years. Parasitological analysis by smear technique detected the presence of T. vivax in 0.3%, while molecular analysis by PCR showed a prevalence in 18.9% of the samples. This study demonstrated the higher sensitivity of molecular analysis in the diagnosis of hemoparasitosis caused by T. vivax in dairy cattle herds.
