title: Differentiating between Besnoitia besnoiti from cattle and Sarcocystis hoarensis from rodents.
abstract: To provide a biological basis for studies designed to establish the mode of transmission of the veterinary pathogen Besnoitia besnoiti, we compared salient features of this pathogen in cattle with those of Sarcocystis hoarensis in rodents. The cysts and cystozoites of these organisms can readily be distinguished morphologically. In contrast to S. hoarensis, which is well adapted to rodents, B. besnoiti fails to mature in jirds or mice and generally is lethal in jirds. Serological reagents discriminately detect these pathogens. B. besnoiti, therefore, can unambiguously be differentiated from S. hoarensis either by morphological or serological methods or on the basis of experimental comparisons of virulence in laboratory rodents.
