Giardia lamblia is the number one intestinal parasite in the United States. Symptoms of giardiasis include upper abdominal pain and distress, flatulence, nervousness, and diarrhea. Multiple stool specimens examined for ova and parasites by nonexpert parasitologists will frequently not provide the diagnosis, and special studies must then be done. Antibiotics, antidiarrheals, certain enema preparations, and oily laxatives can cause a temporary disappearance of parasites from the stool. Treatment of choice is a five-day course of quinacrine hydrochloride. Recently, attention has been brought to the fact that oral sex may be responsible for transmission in a significant number of cases of giardiasis.
贾第虫是美国头号肠道寄生虫。贾第虫病的症状包括上腹部疼痛与不适、肠胃胀气、神经过敏和腹泻。由非专业寄生虫学家检查多个粪便样本中的虫卵和寄生虫，往往无法做出诊断，此时必须进行特殊检查。抗生素、止泻药、某些灌肠剂和油性泻药会使粪便中的寄生虫暂时消失。首选治疗方法是服用五日疗程的盐酸奎纳克林。最近，人们注意到在大量贾第虫病病例中，口交可能是传播途径。
