Studies on sarcocystis in slaughtered pigs

The Swine Sarcocystis were investigated the hearts of 524 slaughtered pigs in the area of Kangwon-do. The rate of Sarcocystis infetion and the morphologic states of the cyst bradyzoite were ivestigated. The results obtained were summarized as follow: 1. The infection rate of swine Sarcocystis investigated 384 breedings pigs were found to be 16.7%. 2. The swine Sarcocystis were observed only the pigs over third parturition(19.8%: 64 herds,∴p＜0.01). 3. The cyst walls detected out from the cardiac muscle were less than 1㎛ in thickness and the size of bradyzoites were 15.7×3.7㎛ in average. 4. The bananashape and ellipical micropore on the surface in the bradyzoites were observed with the scanning electrone microscope.
