Nespora caninumis a parasite which was first detected in Norwegian dogs and has been known as an important abortive cause of cattle. A high abortion rateup to 44% occurs in N. caninumpositive pregnant cows.. Besides, consequence of infection could be culling of the aborted dams, reductionof milk production and weight gain, and increase of veterinary, diagnosisand replacement purchase costs. Various methods have been studied to prevent and control N. caninuminfection in cattle. However, there are no highly effectiveapproaches available in terms ofboth epidemiological and economic aspects so far.
