摘要

人芽囊原蟲(Blastocystis hominis)，是人體常見的原蟲類生物，尤其是在衛生條件較差的熱帶、亞熱帶的開發中的國家最爲常見，盛行率可達30-50%。人芽囊原蟲感染可能引起腸胃道如腹痛、腹瀉、噁心及嘔吐等症狀。台灣地區近年來針對外籍人士的常規健康檢查發現，不合格的原因中以糞便發現人芽囊原蟲最常見。如果需要治療通常以metronidazole優先使用，若治療失敗則可考慮使用trimethoprim-sulfamethoxazole或iodoquinol來治療。人芽囊原蟲目前認定是經由糞口傳染，因此要避免感染，首要工作便是注重個人的飲食衛生習慣如洗手及食物、飲水衛生，尤其是到人芽囊原蟲高盛行地區，如東南亞、印度、非洲地區旅遊時，要避免食入可能受到污染的水或食物。

Blastocystis hominis is a common parasite protozoon of human intestine, with a worldwide distribution, especially in tropical and subtropical countries. The prevalence rates may range from 30 to 50% in those developing countries. Symptoms attributed to infection including diarrhea, abdominal pain, anorexia and vomiting. In prevalence studies based on the entry physical examination, infection with B. hominis had the highest prevalence of parasites detected among these immigrants in Taiwan. The most commonly recommended therapy is metronidazole; if it fails to eradicate carriage stage, the alternative choices are trim ethoprim-sulfamethoxazole or iodoquinol. It is reasonable to assume the fecal-oral route as the most likely for transmission of B. hominis Thus, good personal hygiene such as handwashing, food and water safety are important control measures.
