Giardia lamblia is discussed as the most important parasitic cause of travellers' diarrhoea. The parasitology of this flagellate protozoan is discussed with respect to route of infection, threshold infecting dose, and incubation period. The geographic distribution of giardiasis is widespread, being common in tropical and sub-tropical regions and endemic at a low level in European and North American countries. The predisposing factors are detailed together with clinical manifestations, pathogenesis and diagnosis. Effective therapy may be quinacrine t.i.d. for 5-10 days, metronidazole 200 mg t.i.d. for 14 days or 2 g once daily over 3 days, or a single dose of 1.5 g of tinidazole. Although Entamoeba histolytica is distributed world-wide, it rarely causes travellers' diarrhoea. However, the clinical features, diagnosis and treatment of amoebiasis-related travellers' diarrhoea are detailed.
贾第虫被认为是旅行者腹泻最重要的寄生虫病因。本文讨论了这种鞭毛虫原生动物的寄生虫学，包括感染途径、感染阈值剂量和潜伏期。贾第虫病的地理分布广泛，在热带和亚热带地区常见，在欧洲和北美国家呈低水平地方性流行。文中详细介绍了易感因素、临床表现、发病机制和诊断方法。有效的治疗方法可能是：奎纳克林每日三次，共5 - 10天；甲硝唑200毫克每日三次，共14天，或每日一次2克，共3天；或单剂量1.5克替硝唑。虽然溶组织内阿米巴分布于世界各地，但它很少引起旅行者腹泻。然而，本文详细介绍了与阿米巴病相关的旅行者腹泻的临床特征、诊断和治疗方法。
