영문 초록

330 Samples of the slaughtered cattle heart muscle were collected from the abattoirs of five regions in Kwangwon-do to reveal the frequency of Sarcocysitis infections during January through Decemver in 1991. The samples were inspected for bradyzoites by the trysin digestion technique & the positive samples were fed to dogs & cats for the detection of sporocysts shed in the feces. The results obtained were summarized as follow. 1. The infection rate of bovine Sarcocystis investigated from 330 samples was 43.6%. 2. It revealed that the infection rate of Sarcocystis increased gradually with the advance in the age, 14.5% in below two years, 26.1% in three years, 30.0% in four years, 54.7% in five years, 74.4% in six years, 90.0% in seven years, 100% in older than eight years. 3. The cyst walls detected out from the heart muscles were less than 1㎛ in thickness and the size of bradyzoites were 11.8×2.8㎛ in average. 4. The size of sporocysts shed in the feces of dogs were 15.8×9.8㎛ in average and the prepatent periods ranged from 12 to 16 days. 5. Sarcocystis found in the bovine heart muscles were identified as Sarcocystis cruzi (Hasselman, 1923) Wenyon, 1926.
