ABSTRACT
It has been suggested that the abortion herd pattern could influence bovine foetal neosporosis. Here, a comparison of (i) Neospora caninum DNA-detectability by PCR, (ii) N. caninum-associated lesions and (iii) parasite loads in target organs was made between epidemic and endemic abortion cases. We observed that N. caninum DNA was predominantly detected in more than one organ in the foetuses from herds with epizootic rather than endemic abortion cases (P<0.05, Fisher F-test). The highest parasite burdens were found in the heart in foetuses from outbreaks of epidemic abortion and in the brain in endemic cases (P<0.05, Kruskal-Wallis H-test). Moreover, foetuses from epidemic outbreaks had significantly higher parasite burdens in heart (P<0.05, Mann-Whitney U-test) than endemic abortion cases. Epidemic abortion cases showed higher lesion frequencies in liver (P<0.05, Fisher F-test). This report confirms that the abortion herd pattern is an important factor that influences pathogenesis in natural N. caninum infections.
