단방조충(單房條蟲)의 형태(形態)와 생활사(生活史)에 관(關)한 연구(硏究)

The purposes of this study were to define the life cycle of Echinococcus and its species and subspecies in Korea. The results were as followings: 1. The patent period day of Echinococcus granulosus was 50 days. 2. The life cycle of Echinococcus granulosus was dog-cattle-dog, as cattle-dog originating adult. 3. The sine of the adult worm was measured from 2.2mm to 6.2mm, but most of them was between 3.0mm and 4.0mm (40% of all). 4. Although the number of segments was from three to five proglottids, most of them was 3 proglottids(76.7%), as immature, mature and gravid, respectively. 5. The habitat of the adult worm was recognized as duodenum or pyloric region in the dog. 6. According to the results above, we could be proved that the hydatid cysts of he Echinococcus discovered in Jeju-do, was Echinococcus granulosus granulosus.
