Abstract
Studies were done on tissue reactions to C. bovis in the heart of cattle. Findings in animals with spontaneous and experimental infection were compared and tissue reactions in relation to the location, morphology and morphogenesis of C. bovis were evaluated. In general, the response of the heart to the presence of C. bovis was an inflammatory reaction characterized by the origin of a pseudoepithelial border and a zone of granulation tissue. When necrotic changes started to affect the cysticercus, the inflammatory reaction redeveloped, accompanied by an exudation and a subsequent resorption. Characteristic features were focal necroses of the exudate and the inflammatory border followed by a dystrophic calcification, focal necroses and a dystrophic calcification of individual collagenous fibers and groups of these fibers in addition to a regular appearance of necrotic-like foci typical of a reaction to C. bovis. The location of the cysticercus in a certain part of the lymphatic system of the heart and in skeletal muscles had a considerable effect on the course of inflammation. Differences in the development of inflammation explained concomitant findings of dead and live cysticerci at the same time after an experimental infection.
