A Neurological Presentation of Neosporosis in Calves

Neospora caninum is an important cause worldwide of abortion, stillbirth and calves born weak. Abortion is the major clinical sing associated to Neospora caninum infection, it typically occurs between months four to seven of gestation, but may occur from three months to term. Abortions tend to occur during mid-gestation and it appears that foetuses exposed in early gestation are more likely to abort and that foetuses exposed later are more likely to survive. Although most calves born to infected cows will appear to be clinically normal, there may be some neurological disease that is not readily apparent. However we present here an unusual presentation of the disease with recurrent neurological disease in the newborn calves.
