Abstract

This study was conducted to examine the effect of lysate isolated from macrosarcocysts of Sarcocystis gigantea after inoculation into albino rats to follow up the pathological effect on heart, lung and skeletal muscle fibers. The results showed the presence of pathological changes, represented by hyperatrophy, congestion, associated with hyaline degeneration in myocardium of heart. In lung tissues severe congestion in each right and left lobes concomitant with emphysema, thickening was observed in wall of branchioles and blood vessels at 3-7 days have been seen. In skeletal muscles the result revealed the presence of multinecrotic areas which infiltrated with inflammatory cells accompanied by hyaline degeneration in muscle fibers at 3-7 days after treatment.
