摘要 根據我們實驗室自 1995-1998 年在 10 縣 13 山地鄉 64 所國民學校調查 4,426 位學 童，發現 16％（4－29％）感染蟯蟲。同時在 68 所國民學校檢查 5,121 學童，檢 獲 12％（3－26％）感染頭蝨。1971－1992 年在 10 縣 14 山地鄉 88 村調查原住 民 27,359 人，台灣無鉤絛蟲之感染率 11％（<1－16％）。感染頭蝨，蟯蟲學童及 絛蟲之患者，均接受藥物治療。在實驗室進行一系列性研究：關於蟲體之形態， 中間宿主，實驗動物傳染，免疫，分子生物及台灣絛蟲在志願者體內之發育。同 時，也証明家豬為台灣絛蟲及無鉤絛蟲（波蘭株）之中間宿主，且大多數囊狀幼 蟲寄生在肝臟。由研究結果証明台灣絛蟲與無鉤絛蟲不同。1995 年命名為亞洲 無鉤絛蟲。再者，將無鉤絛蟲又命名為傳統無鉤絛蟲。此論文簡述我們實驗室之 發現報告，臨床現象及原住民之生吃習慣也予以討論。 AbstractAccording to the results obtained by our laboratory and the Department of Parasitology, Taipei Medical College, from 1995 to 1998, the overall infection rate of enterobiasis was 16% (4-29%) among 4,426 primary school students at 64 schools in 13 mountainous districts of 10 counties, and the infection rate of head louse infestation was 12% (3-26%) among 5,121 students. A continuous series of field studies on epidemiology and
chemotherapy of taeniasis asiatica have been conducted between 1971 and 1992 among 27,359 aborigines in 88 villages of 14 districts in 10 counties and 3,104 were found to be infected, giving an overall infection rate of 11 0/0. Laboratory studies have been performed on the morphology, intermediate hosts, experimental infection, immunology and molecular biology. Moreover, development of Taiwan Taenia in one of 3 volunteers has been
successfully demonstrated since 1988. Moreover, the domestic pig was identified as the intermediate host of Taiwan Taenia as in the classical T. saginata (Poland strain). Most of cysticerci were developed in or on the parenchyma of liver. The results indicated that Taiwan Taenia is different from classical T. saginata. It has been named as T. s. asiatica.
Moreover, the classical T. saginata was renamed as T. s. saginata. This paper summarizes findings and reviews those reported by our laboratory. In addition, the clinical
manifestations and eating habits of the aborigines are also discussed
