Abstract


Thirty-four bovine abortions (fetuses) from Paraná State were examined histologically and immunohistochemically. Eight fetuses had non-suppurative encephalitis and miocarditis, and Neospora caninum were detected by immunohistochemistry. Four cows were seropositive to N. caninum. It was the first detection of congenital neosporosis in aborted bovines fetuses, in Paraná State, Brazil.
