In this article special attention is paid to infections with Neospora
caninum as a cause of abortion in cattle. Recently (1996) Neospora can
inum was diagnosed in an aborted calf. This calf originated from a dai
ry herd with 65 cows. During the last seven years on average nine cows
(14 %) have aborted per year on this farm. This finding shows that Ne
ospora caninum infections are enzootic in Belgium.
